Many of us face the problem of hair loss, due to many reasons such as not having proper diet, the external surroundings, pollutions etc. So we need to take a lot of care for preventing hair loss, & so let us see how to stop hair loss. First let us see what is the normal hair growth & hair loss cycle. The normal cycle of hair growth lasts for 2 to 6 years. Each hair grows around just a centimeter, which is less than half an inch, per month during this phase of 2 to 6 years. About 90 percent of the hair on your scalp is growing, and the remaining 10 percent of the hair on your scalp is in a resting phase. Then after around 3 months, the resting hair falls out & then new hair starts to grow in its place. It is actually normal to shed some hair each day as a part of this cycle.

The greater the hair loss on the top of a man's head, the higher his risk of having heart problems, according to researchers who say they've confirmed previous studies linking baldness with heart disease. The new report, published Monday, says men who are losing hair on the crown of their heads have up to a 36 percent greater risk of heart problems, including heart attacks and bypass surgery. Men with a receding hairline are not at increased risk, but those going bald at the crown should pay special attention to their blood pressure and cholesterol levels and lead a healthy lifestyle, researchers said.

Baldness may be more than just a cosmetic indignity: it could be a marker of heart disease risk, especially in men with other risk factors such as high blood pressure or high cholesterol. Heart attacks, chest pain due to blocked arteries (called angina), and the need for balloon angioplasty or bypass surgery all are forms of heart disease, the researchers explained. In men with high cholesterol and severe baldness at the vertex, or crown of the head, heart disease risk was increased nearly threefold compared to men who had high cholesterol but were not bald, senior author JoAnn E. Manson, MD, DrPH, tells WebMD.

Alopecia areata is considered an autoimmune disease, in which the immune system, which is designed to protect the body from foreign invaders such as viruses and bacteria, mistakenly attacks the hair follicles, the tiny cup-shaped structures from which hairs grow. This can lead to hair loss on the scalp and elsewhere. In most cases, hair falls out in small, round patches about the size of a quarter. In many cases, the disease does not extend beyond a few bare patches. In some people, hair loss is more extensive. Although uncommon, the disease can progress to cause total loss of hair on the head (referred to as alopecia areata totalis) or complete loss of hair on the head, face, and body (alopecia areata universalis).

Research into young people’s experiences of hair loss during cancer treatment has found it is a mistake to assume women will be more affected than men. Scientists analysing interviews with recovered young adult cancer patients enrolled in the DIPEx project found that young men were just as affected by chemotherapy-induced hair loss as young women. However until now, men’s experiences of hair loss have been largely ignored.

The association of androgenic alopecia (AGA) with insulin resistance, coronary artery disease and hypercholesterolemia has been previously reported in men, but no such association has been reported in women with female androgenic alopecia (AGA). Female AGA has usually been linked with hyper-androgenism and hirsutism and, most recently, also with polycystic ovarian syndrome (PCOS), even though epidemiological documentation of the latter association is scanty. Polycystic ovarian syndrome is quite common among Caucasian women, and its association with insulin resistance is well documented.

Hair loss is not a pretty thing. It can happen at any time, to anyone. There are many preconceived ideas concerning hair loss today. Many are unfounded, and discussed in our Top 10 hair loss mythbusters. Hair loss is a very common problem and nearly everyone will experience some sort of loss sometime in their lives. There are some hair loss treatments available today that actually work and keep the loss at bay.

Hair loss in woman is not a term that is heard very much. If you're a woman you need to realize that hair loss in woman is a very common and widespread womens health condition. It is estimated that nearly thirty percent of all people suffering from hair loss or hair loss symptoms and in need of hair loss treatments are indeed women. And this number is steadily growing each year with an estimation of between twenty and fifty percent of all women will experience a certain amount of hair loss.

Patients who are afflicted by the condition known as alopecia areata — patchy hair loss — should understand that there is “no reliable, safe, effective, long-term treatment,” said review co-author Dr. Mike Sladden, a dermatologist and senior lecturer at the University of Tasmania in Australia. Alopecia areata accounts for an estimated one in every 50 dermatologist visits in the United States and the United Kingdom, and one study suggests that 1.7 percent of people will be afflicted by it during their lives.

Unlike Male Pattern Hair Loss, “pattern distribution” is not typical for most women with Androgenetic Alopecia. In most cases, for women thinning occurs diffusely without a pattern. Often the frontal hair line is intact, but behind this the scalp becomes visible in the midline. Progressive thinning over time may extend back to the crown area, and often impacts areas on the sides and back of the head, leaving the scalp covered with diffusely thinning hair, but usually no bare areas. Figure illustrates hair loss in women due to Female Pattern Hair Loss.

Look around a crowd, and you'll see that lots of middle-aged men are losing their hair. As Baby Boomers, they have every right to demand, What is science doing about this? Quite a bit, it turns out. A British company, for example, says five guys are walking around with hundreds more hairs than they had before, thanks to an early test of what's been called hair cloning. An American outfit hopes to start testing a similar approach next year.

As long ago as 400BC, the greatest mind in medical history, the Father of Medicine, was studying the causes of baldness. Hippocrates - himself a sufferer of hair loss - noticed that eunuchs (castrated males) seemed able to keep their hair. The connection of harems and hairy men had been noticed by others too and the link between the male hormone, testosterone, and hair loss was first established. Castration of eunuchs prevented them from suffering androgenetic alopecia. However, this is not a treatment considered apropriate in modern times.

Normal aging. Family history of hair loss. Hormonal changes, such as with menopause. A side effect of some medicines, chemotherapy, and radiation therapy. Crash dieting. A prolonged or serious illness. Major surgery. Thyroid disease. Areata. This causes areas of patchy hair loss. It improves quickly when treated, but can go away within 18 months without treatment.

Alopecia, the excessive or abnormal loss of hair, can occur in both men and women. Many men experience androgenetic alopecia (AGA), known to the general public as male pattern hair loss or baldness. Women can develop a similar condition, known as hereditary thinning or female pattern hair loss (FPHL). Since the influence of androgens may be only one of several paths leading to patterned hair loss in women, FPHL may be a more accurately descriptive term until other mechanisms involved in normal aging and hair cycle disruption are clarified.

If my child has lost all his hair except his upper eyelashes two different times, what is this called? And also I'd like you if you would expand and give us the real definitions for alopecia areata, totalis and universalis, and also possibly, I'm going to give you a little bit more here, if you could also tell us the difference between alopecia areata and its many forms and androgenetic alopecia.

ThymuSkin® hair products preserve hair follicles and/or stimulate dormant but live follicles into regrowth. Basically, one can start the program with two or three of the most important products, ThymuSkin® Shampoo, ThymuSkin® Treatment and ThymuSkin® Gel. The fundamental principle for the shampoo is for cleansing the scalp with tiny penetrating thymus peptides. Since these peptides are broken down into the smallest of sizes - only 300 angstroms in length - they do diffuse themselves into the hair follicles better than any other mode of cleanser. They clean out each follicle of accumulated oil, dirt, debris, and other waste and prepare the scalp for receiving the treatment lotion.

The cuticle is thin and colorless and serves as a protector of the cortex. Structure of the hair root Below the surface of the skin is the hair root, which is enclosed within a hair follicle. At the base of the hair follicle is the dermal papilla. The dermal papilla is fed by the bloodstream which carries nourishment to produce new hair. The dermal papilla is a structure very important to hair growth because it contains receptors for male hormones and androgens. Androgens regulate hair growth and in scalp hair androgens may cause the hair follicle to get progressively smaller and the hairs to become finer in individuals who are genetically predisposed to this type of hair loss.

When wearing a wig for the first time it is really important that you build your confidence. It may sound like a strange analogy, but it's a bit like wearing in a new pair of shoes. They always feel a bit uncomfortable the first couple of times you wear them, but after a short while, they mould to fit your feet (still talking about shoes there). A new wig will always feel rather strange at first and it does take a little time to get used to. Try wearing your hair around the house to help you become more accustomed to the way it looks and feels. At first you will do a few double takes when you walk past a mirror! But soon it will become more comfortable and you will relax more.

Ringworm can show small round or oval patches of alopecia and be very similar to AA to look at. Traumatic hair loss, breakage and scaling can be brought on by itching of the scalp and/or hairdressing mishaps, both painful and distressing. Trichotillomania is a condition, not widely known, because those suffering would not wish the loss of hair and the sparse regrowth to be seen. It is a habitual pulling of hairs from the scalp that can be very distressing for the person themselves and the family around them.

Losing one's hair can be a rather traumatic experience, and only certain types of hair loss can nowadays be treated successfully.There are various types of hair loss. Hairs can fall out from the entire scalp, from the region of the forehead or in patches from the crown of the head. Diffuse alopecia is a type of hair loss that is seen in both men and women. With men it is difficult to determine with respect to the androgenetic alopecia. Diffuse hair loss tends to affect the whole scalp, rather than specific areas of it. It can occur at any age. The first signs are of increased hair loss which is followed after a while by recognizable thinning of the hair.

The human body is completely covered with hair follicles, except on the palms of the hands, soles of the feet, genitals and lips. Hair follicles are pouch-like tubes of skin cells that contain the hair root. Most follicles are tiny and many of the hairs they produce do not grow long enough to protrude from the pore. Hair is made mainly of a protein called keratin. The only living part of the hair is the root (sometimes known as the bulb), which is anchored to the base of the follicle. The follicle supplies oxygen and nutrients to the root, and lubricates the hair shaft with an oily substance called sebum. Hair is in a constant cycle of growth, rest and renewal – it is natural to lose some hair each day. Hair grows in phases, with around one in ten head hairs ‘resting’ at any given time. The colour, curl, length, thickness and amount of hair depend on genetic factors.

Dihydrotestosterone, also known as “DHT,” is an incredibly potent androgen found in the human body, primarily in males. DHT is a byproduct of the male hormone testosterone. While testosterone is critical for male development and masculine characteristics, it is susceptible to the effects of an enzyme found naturally in our bodies called 5-alpha reductase (5AR). When this enzyme reacts chemically with testosterone, a chemical conversion occurs that transforms testosterone into DHT. DHT attaches to androgen receptors in the scalp, which can shrink the hair follicle and eventually lead to the hair follicle dying off and falling out. While there is always some naturally occurring DHT in the body, excess levels of it cause hair loss by attacking genetically susceptible hair follicles in the scalp, as well as causing prostate problems for men. These side effects can occur at any age, but become particularly prevalent as males become older.

Hair does not really serve any important function since a person can certainly live without it! Yet, our hair and how it looks is a very important part of our self-image. So when a child loses their hair, it is a disturbing event for both youngster and their parents.

The registry has been established by the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), a part of the National Institutes of Health (NIH). The new registry will be located at the University of Texas M.D. Anderson Cancer Center in Houston, with affiliated centers at UCSF, the University of Colorado, University of Minnesota, and Columbia University.

Hair loss during adolescence can mean a person may be sick or just not eating right. Some medications or medical treatments, like chemotherapy treatment for cancer, also cause hair loss. People can even lose their hair if they wear a hairstyle that pulls on the hair for a long time, such as braids.

"Medical treatment and changing hair practices are critical for stabilizing disease and preventing progression of these hair loss disorders. However, existing hair loss has devastating psychosocial consequences on affected patients and is not addressed by those measures. While, historically, blacks have been shunned away from hair transplant procedures because of the challenges of hair harvesting and concern about the risks of hypertrophic and keloidal scarring, with use of proper techniques in appropriately selected patients, hair transplantation allows us to do something positive to improve appearance for these suffering women," said Dr. Callender, clinical assistant professor of dermatology, Howard University College of Medicine, Washington, and in private practice in Mitchelville, Md.

People with the condition called trichotillomania feel compelled to pull out their hair. The effects are seen on both the scalp and the upper eyelids. In the affected areas there are hairs of different lengths. When looked at under the microscope they show fractures.

When you think of hair loss, what image comes to mind? If you're like most of us, it's probably not a picture of a healthy woman -- but by the age of 50, over 50 percent of women are experiencing some hair loss. And believe it or not, the solution isn't as simple as a bottle of Rogaine. In fact, there actually four types of hair loss common in women, each with its own appearance, causes, and treatments. We spoke to Matt L. Leavitt, MD, a board-certified dermatologist and author of Women and Hair Loss (www.womenandhairloss.com), for some insight:

Spencer David Kobren vividly remembers the day he saw the light. Or to be more precise, the day he saw a little telltale patch of white. It was Dec. 31, 1986. Kobren was 22. He knew his life had changed irrevocably. "It was devastating, man," he says, his tone mournful and anguished. "I felt like I was losing a limb. Once you cross that line, there's no going back." His hair, lush and dense as a tropical forest, was starting to disappear. So began an odyssey to restore what time and genetics were slowly robbing. Kobren tried lotions made of keratin and potions infused with amino acids. He tried hanging upside down. He consulted psychics. He tried zapping his noggin with electrical charges, wrapping it with hot towels, rubbing it with cayenne pepper, shooting it up with hormones. He spent years and thousands of dollars on a fruitless, hairless quest.

The hair follicle is a structure that encases the lower part of the hair shaft. Each follicle contains blood vessels that nurture new hair growth. All hair follicles are present at birth; throughout the lifetime each follicle grows and sheds single hairs in a repetitive cycle (show figure 1). The growth phase for a single new hair lasts two to three years. At the end of this time, growth ceases and the follicle enters a resting phase. After three to four months in the resting phase, the hair is shed and the next growth cycle begins. On a normal scalp, approximately 80 to 90 percent of follicles are growing at any time. Each day, about 75 follicles shed their hair while the same number enter a new growth phase.

Folliculitis decalvans, also known as alopecia folliculitis or acne decalvans, is an inflammatory reaction in hair follicles on the scalp that causes redness (erythema) and pus-filled blisters (pustules). It leads to scarring and permanent hair loss. Traction alopecia occurs as a result of improper hair care and prolonged use of certain hair-styling techniques. Cosmetic treatments (e.g., dyes, tints, bleaches, permanents) are generally safe; however, if treatments are done incorrectly, or if the chemicals are used for too long, the hair becomes brittle and breaks easily. Hairstyles that pull the hair tightly, and excessive shampooing or brushing can also cause hair loss. Braiding, permanents, excessive heat, and hair straightening cause hair shaft weakness. Hair styling techniques such as hair weaving, corn rowing, and the use of hot combs to straighten hair can cause permanent hair thinning and scarring.

Everyone loses some hair every day. Losing up to 100 hairs a day is normal. But if hair loss runs in your family, you could lose a lot more hair. Over time, you may end up with bald spots or hair that slowly gets thinner. About half of all people have this type of hair loss by around age 50.1, 2 Other factors, such as diseases and medicines, also can cause you to lose more hair than normal. Although hair loss is fairly common, it can be a tough thing to live with, especially when it changes how you look. But there are ways you can treat your hair loss.

Hair loss can occur from many causes, including aging, illness, infections, scalp conditions, stress, hormone changes, and medications. Hair loss can also occur with HIV. There are additional reasons that hair loss may occur with HIV besides the virus itself. Many medications used to treat HIV can cause hair loss. People with HIV are susceptible to a wide variety of viral, bacterial and fungal infections. Such infections can involve the scalp, causing hair loss. The infections can also involve other organs, stressing the body. Premature aging can occur with HIV, resulting in accelerated graying of hair and hair shedding.

Changes to hair on the scalp. Many women notice that the hair on their head is thicker during pregnancy. Many lose a lot of hair a few weeks or months after delivery. These changes are normal. Hair growth generally returns to its regular growing cycle within six months after delivery. When you're not pregnant, the hairs on your head grow in a regular cycle. During pregnancy, hairs tend to stay in the resting phase longer. And much more of your hair is in the resting phase at any one time. Therefore, fewer hairs fall out each day. This causes your hair to seem thicker and fuller.

For many people, hair loss is one of the more trying aspects of cancer treatment. When hair falls out, it affects our self-image and our quality of life. But you don’t have to despair – you can go a long way towards boosting your own self-confidence with an educated attitude and some advance preparation. Everyone's experience is different, so it’s important to become well informed about how your particular treatment affects hair loss. Talk to your doctor, nurse, or social worker about what to expect.

HairSite: I think that the common conception out there is that Farrell is a large company already. How large are you? Richard Farrell: Right now we have five locations with more opening soon. That's not very large compared to the big chains. Instead our locations cover both coasts and we really consider them to be world centers. Remember, our clients come from almost every city and every country on the planet. So we're not large in terms of the number of salons operating but in some ways we're huge!

Unlike the receding hair line creeping over a man's scalp, hair loss sneaks up on a woman. Maybe she sees a few more hairs in her favorite brush. Her ponytail feels skinnier. Her part widens. Eventually she notices she can see her scalp peeking through in a photograph. Whatever the telling sign, female pattern hair loss can be traumatic. But women today are less likely to suffer in silence than a decade ago; doctors report that women increasingly are coming forward to seek remedies. Locks we love In some cases, pinpointing the cause is the first step to a cure, though the source of hair loss in women is not always as clear as it is in men. The hormone fluctuations of puberty, pregnancy and menopause can cause hair to shed. So can the stress of general anesthesia, illness, anemia, crash diets and thyroid abnormalities. Some women -- and a few men, too -- suffer a compulsion to tug at the hair, damaging the follicles.

Some fashion models with beautifully shaped heads may choose baldness as part of their look. But for most women, loss of hair -- or even thinning of it -- is highly upsetting, often much more so than for men. The relatively extensive hair loss that often occurs after pregnancy frightens many a new mother. And women commonly describe hair loss as the most devastating aspect of chemotherapy, even though they know their hair will grow back after the treatments are over.

Hormones have a great effect on hair, which is why many women notice changes during and after pregnancy and around menopause. After menopause, the ovaries may produce more androgens (male hormones) than estrogen and this can result in hair loss. (Male baldness is related to increased testosterone). A dermatologist or plastic surgeon can do scalp biopsies and have the hair follicles studied, which may be helpful in determining androgen effects. Some medications, severe stress, malnutrition, iron deficiency and an underactive thyroid may all cause hair loss, so blood tests also are useful.

Hair loss can occur as thinning hair or complete baldness. The hair loss may be on the head or any other part of the body that normally has hair, such as the eyebrows. What is going on in the body? There are many causes of hair loss. The most common form of hair loss is due to male pattern baldness, in which hair is lost from the front and top of the scalp. Other types of hair loss can create different patterns. Treatment depends on the type and cause of baldness. What are the signs and symptoms of the condition? The primary symptom is hair loss. Other symptoms can vary widely depending on the cause of the hair loss. Those with male pattern baldness have no other symptoms. The location of the hair loss also differs depending on the cause.

Be sure to read through the treatments discussed for men, as many of those will be appropriate for women. Below are listed some of the most effective treatments for women's hair loss. Cosmetic treatments are something women know a lot about. Many of us won't leave the house without applying a cosmetic treatment on our faces, but often we don't consider this as a treatment for hair loss. Obviously, cosmetic treatments for hair loss do not change the actual hair loss; they simply change your appearance. No chemical or surgical procedures are used. Wigs are the most common cosmetic approach to female baldness. Wigs can be made from natural hair and from synthetic hair. Wigs made from natural hair can look better at first, but they do not last as long as synthetic wigs. Synthetic wigs are also easier to maintain.

It's a big problem for millions of women, and it can happen at any age. But there is relief thanks to better ways to diagnose the problem and aggressive treatments to bring hair back. For many women, hair defines personal style. It's no wonder the loss of this crowning glory can be psychologically devastating. "I was blown away I was so embarrassed about it at first," said 25-year-old Esperanza Castillo, who may seem an unlikely victim. "I never thought I would have a problem with my hair." Forty-three-year-old Felicia Willis was also horrified when clumps of hair began showing up in her comb.

Hair loss is a major concern for men and women the world over. Unfortunately, many consumers answer ads for hair replacement products and procedures before getting the facts about hair loss. While some cases of hair loss are inherited, others are caused by disease and poor diet and may also result as the side effects of some medical treatments. In some cases, people with hair loss conditions can re-grow hair through correct diagnosis and medical treatment while others may decide to seek alternative hair replacement options. Dermatologists specializing in treating diseases of the hair and skin may evaluate patients’ hair problems to determine what, if any, treatment may be right for that patient. Before spending hundreds of dollars on products and procedures, it is important to get a professional opinion on whether or not the problem will respond to medical treatment.

Transplantation to the eyebrows is a procedure designed to restore growing hair to eyebrows that are overly thin, scarred, or completely missing. The donor hairs usually come from the scalp which, when transplanted into the eyebrows, continue to grow for a lifetime and therefore need to be trimmed typically once a month. To provide a natural appearance, the hairs are transplanted primarily one and occasionally two at a time, the natural way eyebrow hairs grow. This is a very delicate procedure, requiring perfect placement of these hairs into tiny (half-millimeter) incisions that are angled at just the right direction and positioned to mimic natural growth. The use of all-microscopically dissected grafts allows their placement into the smallest possible incisions so as to minimize scarring and damage to already existing hairs.

Although it is possible for the sufferer to discover the source of the allergy by trial and error it is better by far to seek the advice of a qualified dermatologist as soon as the problem becomes evident. Changing your make up may simply prolong the discomfort as the same ingredient which is causing the allergic reaction may be present in other makeup products. The longer the condition persists the more damage you may be doing to the follicles, which may result in noticeable thinning of the lashes . Be safe by always seeking medical advice if you notice hair loss resulting in the appearance of a bald patch, however small, on any hair bearing part of your body. It may not result in eyelash loss but it is still more than likely to be symptomatic of a condition in need of treatment.

Hair Loss and Baldness affect approximately 20 million women and 40 million men in the United States. In a society often obsessed with physical appearance, losing one's hair can be very painful and can negatively affect self-confidence and self-esteem. Fortunately, losing your hair does NOT mean you must also lose your attractiveness, self-confidence, and social life. There are many things you can do to feel better about your hair loss and yourself.

Hair Restoration Surgery encompasses numerous Procedures & Terms: ALOPECIA: The medical term for baldness. ANDROGENIC ALOPECIA: The most typical pattern of balding whereby the balding pattern is controlled by hormones and passed along via heredity. ALOPECIA REDUCTION: A procedure that involves removal of a strip of balding upper scalp in the crown and vertex areas. The natural flexibility of the scalp is used to stretch the surrounding hairy scalp into place. It can be repeated in certain cases. See also "Scalp Reduction."

Women lose hair on an inherited (genetic) basis too, but the female pattern is more diffuse, with less likelihood of the frontal hairline being lost. Although some women may notice hair thinning as early as their 20s, the pace of hair loss tends to be gradual, often taking years to become obvious to others. (It's common to hear women with what appear to have a full head of hair exclaim, "This is nothing--you should have seen how thick it used to be!") Notions about baldness being inherited through the mother's family, just like stories about hats choking off follicles or long hair pulling on the roots, are just folklore.

A Japanese medical team has found that a form of antibiotic could prevent cancer patients from losing hair during chemotherapy, a doctor involved in the research said Monday . Toshiyuki Sakai said his team had found "alopestatin" reduced hair loss by 70 percent when used on rats also given etoposide anti-cancer drugs. Etoposide is widely used to treat lung and other cancers but can cause hair loss. Sakai, professor at Kyoto Prefectural university of Medicine, said his team was hoping to to put the agent to practical use in the future. "I want people to know that few studies have been made on reducing side-effects of anti-cancer drugs," he said.

About 90 percent of hair on the scalp grows continually. The other 10 percent of scalp hair is in a resting phase that lasts two to three months. At the end of the resting stage, this hair is shed. Shedding 50 to 100 hairs a day is normal. When a hair is shed, it is replaced by a new hair from the same follicle and the growing cycle starts again. Scalp hair grows about one-half inch a month. As people age, the rate of hair growth slows. What causes excessive hair loss? Most hair shedding is due to the normal growth-rest cycle, and losing 50 to 100 hairs a day is no cause for alarm. When concerned about excessive loss of hair or dramatic thinning, consult a dermatologist.

There is a close relationship between infection outbreaks on teeth and the presence of alopecia areata or localized alopecia, a type of hair loss which has an unknown origin. Alopecia areata starts with bald patches on the scalp, and sometimes elsewhere on the body. The disease occurs in males and females of all ages, and experts believe that it affects 1 out 1000 people. Research by professors José Antonio Gil Montoya and Antonio Cutando Soriano, of the Department of Stomatology of the University of Granada, advises going to the dentist when patients notice localized hair loss, in order to receive a careful examination of their oral health. “Alopecia areata is a dermatitis which presents the following signs: The typical pattern is for one or more round bald patches to appear on the scalp, in the beard, or in the eyebrows, or to undergo a loss of eyelashes. Alopecia areata is thought to be an auto-immune disease”, stated the researchers. Hair re-grows in most patients after several months. However, in a quarter of all patients the condition recurs once or more. According to professors at the UGR, the affected hair follicles are not totally destroyed. Therefore, hair can grow back, although patients who have already suffered from alopecia areata may have recurrences.

Hair loss or alopecia can be caused by fungal infections, inflammatory conditions, trauma, or as a side effect to some medical conditions (like hypothyroidism) or their treatments (chemotherapy for childhood cancers). Tinea capitis: is a scalp infection that is caused by a fungus. It can cause patches of hair loss, with broken off hairs (black dot ringworm), scales, enlarged lymph glands, or the formation of a kerion, a large, red, boggy nodule on the scalp. Your doctor may do a KOH examination of the hairs, have a fungal culture done, or he may just treat your child with an antifungal agent, such as griseofulvin. These medicines are taken for at least 6 weeks, usually with fatty meals which can help it to be absorbed better. You can also wash your child's hair with a shampoo that contains selenium sulfide at least twice a week to make him less contagious.

Tinea capitis presents with erythema, scaling and broken hair shafts on exam. Evaluation includes KOH or fungal culture of broken hair shaft and appropriate oral antifungal treatment. Alopecia areata presents as smooth round bald patches in the scalp, beard area, or eyebrows. Evaluation includes TSH, CBC, and RPR to evaluate for associated autoimmune disease or syphilis. The condition is self limited but referral for treatment is appropriate for multiple areas of involvement or large surface area involved. Traumatic alopecia includes trichotillomania and traction alopecia. Treatment involves pinpointing the underlying cause and emphasizing behavior modification.

Patient history of alopecia: onset of hair loss, hair loss pattern (diffuse or focal), rate and timing of hair loss, other scalp symptoms (itching, burning, tingling)
Personal history: dietary changes, diet, hair-care routine, hygiene products, medications (prescription medications, vitamins, over-the-counter [OTC] medications, and herbal remedies), stress, major illness
Female patient: menstrual and reproductive histories
Any family history of alopecia, patient's concurrent systemic/chronic illness, physical stress, medication, environmental exposure, psychiatric disorders, hairstyle, signs and symptoms of hormonal abnormalities
Physical examination:
1. Scalp exam for any scars, erythema, scaling, or inflammation
2. Density and distribution of hair
3. Hair shaft exam for caliber, length, shape, and fragility
4. Thyroid palpation to determine thyroid size, nodularity, or vascularity
Use "pull test" technique for hair loss. Grasp about 60 hairs between the thumb, the index, and the middle fingers. The hairs are then gently but firmly pulled. A positive test (2–10 hairs obtained) indicates an active hair shedding.

If a patient demonstrates positive hair-pull tests all over the scalp, he/she may be warned he/she will most likely lose all of their hair. Next, provide anticipatory guidance during the period of extensive hair loss as the cycle reestablishes and regrowth begins.

Finally, determine if eyebrow, eyelash, axillary, or body hair is affected. Examine hair density in other areas such as the face and extremities. A female patient who presents with thinning scalp hair and demonstrates increased facial, thigh, chin, or chest hair may have an androgen excess.

The most effective current solution for baldness is hair-replacement surgery, in which follicles are painstakingly moved in small bunches from the thick hair on the back of the head to the barren acreage on top. But what if it were possible to move an entire, full and durable scalp from another person, albeit a dead one, all at once? That prospect set hundreds of hair-restoration specialists atwitter at a late-September scientific conference in Las Vegas, where transplantation expert Maria Siemionow presented research that many believe will make such a thing a reality one day. Siemionow, who is renowned for her groundbreaking work in the field of facial transplants, said her team at The Cleveland Clinic has developed a treatment in lab animals that reduces the length of time any recipient must be on immunosuppressant drugs to just a week. Today, the recipient of any transplant must stay on fairly toxic and expensive medication for life, which makes it untenable to do transplants for anything less then life-essential organs. It remains untested in humans. The scientist told her audience at the International Society of Hair Restoration Surgery's convention that her aim is to make full-scalp transplants possible for severe burn and trauma victims. But that didn't keep listeners from imagining the cosmetic applications.

Baldness is loss or lack of hair, usually from the top of the head. It may also occur on other parts of the body where hair normally grows. Baldness is usually part of the aging process. Some diseases and drugs may also cause baldness. Hair loss may be either temporary or permanent, depending on the cause. How does it occur? There are several types of baldness: male and female pattern, local, and general. Male-pattern baldness runs in families. This hereditary baldness usually happens above the forehead, causing a receding hairline. It also happens at the crown of the head. Over time, the bald spots increase in size until the entire top of the head is bald and there is hair only on the sides of the head. Sometimes female-pattern baldness occurs in women. Usually it causes the hair to thin in the front, on the crown, or on the sides.

"It's one of the leading ways people can establish their individuality and express their style," says Jerome Shupack, M.D., professor of clinical dermatology at New York University Medical Center in New York City. "Hair has had sociological importance throughout the ages." Because of its importance, anything that happens to our hair that we can't control--falling out or turning gray, for instance--can be the source of much anxiety. In the United States, some 35 million men are losing or have lost their hair from male-pattern baldness, according to the American Hair Loss Council. Approximately 20 million women have experienced a similar loss of hair (from female-pattern hair loss), and an estimated 2.5 million Americans have lost their hair due to other causes.

Hereditary-pattern baldness is the most common cause of hair loss. Hereditary-pattern baldness is not really a disease, but a natural condition caused by some combination of genetics, hormone levels and the aging process. Almost all men and women will notice hair loss or hair thinning as they age. However, up to 40% of men and women will experience a more obvious form of this condition. Hair loss typically begins in the 20s and 30s, although in women the changes are most noticeable after menopause. The condition is also called androgenetic alopecia and, in men, male-pattern baldness. Researchers have begun to understand more about the cause of this type of hair loss. Under the influence of a form of the male hormone testosterone, the normal cycle of hair growth changes, resulting in shorter, thinner or "miniaturized" hair. Eventually, hair growth in certain parts of the scalp stops entirely, which causes the typical pattern of hair loss. Contrary to the folk wisdom that baldness is inherited from one's mother's family, the condition seems to depend on genes contributed by both parents.

Female pattern hair loss is the most common type of hair loss in women. The condition is genetically predetermined, though factors such as age and androgen (male sex hormones) levels are commonly associated with the timing of its onset and how far it progresses. It most often begins during menopause (end of menstruation) but may begin as soon as puberty in very rare cases. Dihydrotestosterone (DHT) and an enzyme (a complex protein found in body cells) known as 5-alpha reductase are involved in the androgenic alopecia process. Women with large amounts of this enzyme produce excess amounts of DHT, the hormone primarily responsible for hair loss. This subsequently reduces levels of estrogen, a hormone that naturally counteracts the affects of DHT. Over time, this excess DHT causes the hair follicle to shrink or even stops hair growth.

In ancient Egypt physicians used the electric catfish that inhabit the Nile River to shock their patients into good health. Since then, electric and magnetic stimulation devices have fallen in and out of favor with the medical establishment. By the mid-20th century, almost every form of electromagnetic therapy, including electroshock treatments for patients with mental disorders, had been put on the same shelf with leeches and blistering cups. There was no question that electric therapy occasionally produced results. The problem was that no one could explain how exposure to an electromagnetic field did the body good.

Your hair loss may have started with a few extra hairs in the sink or in your comb. But now you can't look in the mirror without seeing more of your scalp. Baldness typically refers to excessive hair loss from your scalp and can be the result of heredity, certain medications or an underlying medical condition. Anyone — men, women and children — can experience hair loss. Some people prefer to let their baldness run its course untreated and unhidden. Others may cover it up with hairstyles, makeup, hats or scarves. And still others choose one of the medications and surgical procedures that are available to treat baldness. Before pursuing any of these treatment options, talk with your doctor about the cause of and best possible treatments for your hair loss.

If clumps of your hair start to fall out from a common form of baldness, a new review of existing research unfortunately offers little comfort. Patients who are afflicted by the condition known as alopecia areata -- patchy hair loss -- should understand that there is "no reliable, safe, effective, long-term treatment," said review co-author Dr. Mike Sladden, a dermatologist and senior lecturer at the University of Tasmania in Australia. Alopecia areata accounts for an estimated one in every 50 dermatologist visits in the United States and the United Kingdom, and one study suggests that 1.7 percent of people will be afflicted by it during their lives. The condition often causes patchy hair loss; meaning hair in some parts of the body falls out while remaining in others. In some cases, however, affected patients can lose all of their scalp hair or even all of their body hair. Most affected people begin developing bald spots before the age of 20. Many cases of alopecia areata get better over time, although hair loss often returns.

Hair restoration patients with more advanced patterns of hair loss usually desire to have the maximum number of hair grafts transplanted in as few surgeries as possible. At Hasson & Wong we classify any hair transplant surgery requiring 2000 or more grafts a megasession. Our patients enjoy more dramatic results with fewer hair transplant procedures when we perform these megasessions. Follicular unit transplantation combined with dense packing in megasessions are providing patients with previously unimagined results in a single surgery. At Hasson & Wong we believe this type of surgery represents the future of surgical hair transplantation and we continue to push the envelope to achieve even more profound results.

Baldness, also known as alopecia, is hair loss, or absence of hair. Baldness is usually most noticeable on the scalp, but can occur anywhere on the body where hair grows. The condition is more common in men than in women. There are a number of hair replacement techniques that are available, although hair replacement surgery cannot help those who suffer from total baldness. Candidates for hair replacement must have a healthy growth of hair at the back and sides of the head. The hair on the back and sides of the head will serve as hair donor areas where grafts and flaps will be taken.

There are many causes of hair loss in men and women, including disease, nutritional deficiency, hormone imbalance, and stress. However, by far the most common cause is what is called adrogenetic alopecia. Alopecia is simply the medical term for hair loss. Androgenetic refers to the fact that both a genetic predisposition to balding, and the influence of androgens, or male hormones, play a part in this type of hair loss. In fact, there is a third factor, which is the passage of time, or aging.
