Information on Traction Alopecia

Traction alopecia is caused by chronic traction (pulling) on the hair follicle. Traction alopecia mostly occurs in African-American women and men who braid their hair too tightly. It is also common in other ethnic groups known for traditional hair styles that involve pulling the hair.

There is also seen a pronounced traction alopecia in the beard area of this Sikh man. The Sikh men do not cut scalp or beard hair. The beard hairs are pulled straight and then twisted and tightly knotted. Daily knotting often results in this form of traction alopecia.

Men who attach hairpieces to their existing hair also suffer from this type of hair loss. The traction alopecia in such cases can also lead to permanent hair loss if the hairpiece is attached in the same location over a long period of time.

If we put the examples from ethnic groups aside, traction alopecia occurs most often in pre-teenagers, teenagers, young adults then it does in older men and women.

It is a very unfortunate state that hair styles and fashions and hair styling methods are causing baldness and hair loss among today’s younger generations. The hair loss in all such cases is mostly due to Traction alopecia. The hair loss is caused by long term hair pulling and breakage due to very tight hair braiding, hair weaves and cornrows.

The over use of hair style aids such as sponge hair rollers or curling irons may also promote traction alopecia. Traction alopecia often shows as distinct patches of hair loss in those areas where the hair and hair follicles have been put under excessive strain. The hair loss may occur anywhere on the scalp depending on the nature of the hair style or process that is causing the traction alopecia. Prolonged traction alopecia can lead to cicatrization of the new hair follicle and permanent hair loss.

Traction alopecia is reversible if diagnosed in the early stages. Permanent hair loss can occur too slowly for immediate detection. Hair loss is often occurs in the front, and hair line but is also subject to the immediate adjacent area to where the hair is being pulled and damaged.

An effective treatment is to simply avoid hair styling that puts excessive strain on the hair. Even with removal of the cause of traction alopecia it may take up to three months for the hair to recover. Areas of scalp subjected to chronic traction alopecia may never fully recover.

Traction alopecia is generally a non-scarring, non-inflammatory form of hair loss although long term use of hair styles involving traction over 3 or more years may result in a mild immune cell infiltrate and irreversible scarring damage to some hair follicles. Any form of chronic traction alopecia will eventually lead to fibrosis around hair follicles and total destruction of some hair follicles. Once destroyed the hair follicles will not re-grow under any circumstances hence chronic traction alopecia can be described as a scarring cicatricial alopecia.

Permanent traction alopecia does not respond to medical treatment such as minoxidil or finasteride due to non-genetic nature of hair loss. The only way one can treat traction alopecia is with hair transplants. Follicular unit hair grafting has been identified as the only practical solution to treating traction alopecia. Number of patients with traction alopecia coming to hair transplant clinics is generally increasing and the treatment is providing them a good response.

Female Pattern Baldness

Female pattern baldness a.k.a. alopecia in women is the most common form of hair problem that women come across. It involves a typical hair loss pattern, resulting from hormones, aging and genetic predisposition.

Hair loss pattern resulting from alopecia in women

Unlike in men, female pattern baldness does not cause hair loss in a well-defined pattern. The hair starts thinning all over the head though there is no hair line receding. It is rare for alopecia in women to result in total baldness.

In the case of females, the scalp hair loss may begin at any age though usually after 40.
The patterns of female pattern baldness can vary considerably in appearance and may include:

Diffuse thinning all over the scalp often with more noticeable thinning toward the back of the scalp.

Diffuse thinning all over the scalp with more noticeable thinning toward the front of the scalp but not involving the frontal hair line.

Diffuse thinning all over the scalp with more noticeable thinning toward the front of the scalp, involving and sometimes breaching the frontal hairline.

Symptoms of alopecia in women

In normal condition a woman tends to lose around 100-125 hairs per day. Losing more hair than that indicates that the condition is not normal.

The following two conditions indicate alopecia in women

Hair thinning over the entire head

Hair loss at the crown or hair line, from mild to moderate

Causes of female pattern baldness

The disease is triggered by the presence of a male hormone called testosterone in female body. Testosterone is produced by androgen hormone.

Certain women are decidedly more sensitive to testosterone than others. This sensitivity results in hair thinning on their scalp. Testosterone interacts with the enzyme 5 alpha reductase produced by the body. The interaction causes the production of DHT within the hair follicle.

DHT causes production of shorter and finer hairs. When DHT is not received well by hair follicles, it causes reduced blood supply and it causes hair thinning on the scalp.

Diagnosis of female pattern baldness

Women tend to have less obvious hair loss patterns than men and they face non-pattern hair loss more frequently than men. Diagnosis of female hair loss should be conducted by a trained and experienced physician.

The physician diagnoses this hair disease on the basis of hair loss appearance and pattern. He also checks whether other possible hair loss causes can be ruled out. He may also go for a skin biopsy or other procedures to diagnose the medical disorders.

Treatment

The diagnosis of female pattern baldness should be followed by a proper treatment. The patient is usually administered Rogaine. Another medicine is Aldactone, which is useful especially for the women experiencing hair fall after menopause. A modern and popular method used in the case of female pattern baldness is hair transplantation.

Female Pattern Baldness: Diagnosis and Treatments

Clinical features of pattern baldness in women usually occur during early teens and late middle age. This is shown by the gradual thinning of hair over the frontal area. Usually, pattern baldness in women is not accompanied by increased shedding of hair, but unlike telogen effluvium, hair loss may be seen from the start. The scalp becomes more and more visible as the disease progresses.

Most of the time, the central part of the head widens due to diffused reduction of the hairs density, which involves the frontal scalp and crown. Some women may experience hair loss on some small areas of the frontal scalp while others may experience the effect on the entire scalp including the areas of parietal and occipital. During hair loss, women usually retain a rim of hair along the frontal hairline.

In some cases, hair volume may still appear normal but the hair would stop growing to its previous length and normally results to thin distal ends. Female pattern hair loss is seen on women by visual decrease in hair density while in men, it is by baldness on the affected areas.

Treatment of Androgenetic Alopecia

Hair loss is a result of abnormal hair cycle. Because of this, it is theoretically reversible. However, the current treatment options have limits in their performance and in some cases, only small improvements in hair density can be seen. Advanced pattern baldness may already be difficult to treat because irreparable damages may have already taken place on the follicular stem cell when inflammation surrounded the bulge area of the follicle. Some systematic treatment plans for this case include:

The current treatment for pattern baldness is Minoxidil. The exact mechanism by which Minoxidil works is not known but the treatment appears to affect the hair follicle in three ways: it increases the span of time follicles spend in anagen, it rouses follicles that are in catagen and it enlarges the actual follicles. In effect, vellus hairs enlarge and are converted to terminal hairs, and shedding is reduced.

Finasteride has been effective on men with pattern baldness but definitely it was risky on women. This regimen is not advisable for women who are still in their childbearing age because of the presence of 5a-reductase inhibitors that may cause external genitalia abnormalities in male fetuses.

Hairstyling, teasing, coloring, permanents, and the use of hair spray are means of coping with the cosmetic effects of pattern baldness. However, when the hair loss is grave, the affected person may opt to use wigs.

Hair transplantation is another option since it has already been accepted in treating pattern baldness on men. Now, it is also being used to treat female hair loss although only a very few women go for this type of treatment because of the cost and the possible trauma that may go with it.

For those women who have encountered ineffective and unsuccessful treatments for hair loss, surgery may be another option and thus, the most suited method for them.

Balding Solution for Men and Women

Androgenetic alopecia (male and female pattern balding) is by far the most common cause of hair loss amongst men and a serious problem for many women. There are three important components which are responsible for both female and male balding:

1. A genetic predisposition for balding to occur

2. Excessive presence of male hormones

3. Aging – enough time for the first two factors to occur

Both men and women produce male hormones that have a useful role to play in both sexes; but the fact that androgens occur in much higher concentrations in men explains why male pattern baldness is more common than the female balding.

DHT the root cause of hair loss

It is metabolism of male hormones (androgen/testosterone) which is main cause of hair loss and male and female pattern balding both in men and women.

The metabolism of androgen involves an enzyme called 5 alpha reductase which combines with the hormone (testosterone) and converts it to DHT (Dihydro-testosterone). DHT is a natural metabolite of our body.

The cause of male and female pattern balding

Some individuals, both men and women, are genetically pre-disposed to produce more DHT than the normal individuals. It is this accumulation of DHT and its effect on the cells inside the hair follicle and root which is one of the primary causes of male and female pattern balding.

When DHT gets into the hair follicle and root, especially a region called the dermal papilla, it changes the cell’ activity and prevents necessary proteins, vitamins and minerals from providing nourishment needed to sustain life in the hairs of those follicles. Consequently, hair follicles are reproduced at a much slower rate.

This shortens their growing stage (anagen phase) and or lengthens their resting stage (telogen phase) of the follicle. DHT also causes hair follicle to shrink and get progressively smaller and finer. This process is known as miniaturization and causes the hair to ultimately fall. DHT induced androgenetic aloepcia is responsible for 95% of all hair loss.

Blocking the synthesis of DHT at the molecular level forms the basis for the treatment of MPHL (male pattern hair loss) and FPHL (female pattern hair loss). There are many natural DHT blockers and a number of drugs which are used for medical hair restoration.
