Female
Pattern Baldness
Female Pattern Baldness (FPB) or Androgenetic Alopecia is a genetic
condition that results in permanent hairloss. FPB is a result of hormonal
activity. Testosterone in the scalp breaks down, creating Dihydrotestosterone
(DHT). DHT causes the hair follicle to weaken and ultimately perish.
The conversion from testosterone to DHT is driven by an enzyme called
5-alpha reductase, which is produced in the prostate, various adrenal
glands, and in the scalp. Over time, the action of DHT causes the
hair follicle to degrade and shortens the anagen phase.
Though the follicle
is technically still alive and connected to a good blood supply--it
can successfully nurture a transplanted follicle which is immune
to the effects of DHT--it will grow smaller and smaller. Some follicles
will gradually die, but most will simply shrink to the size they
were when you were born which produce weaker hairs. With a steadily
shorter growing cycle, more hairs are shed, the hairs becoming thinner
and thinner until they are too fine to survive daily wear and tear.
Balding hair gradually changes from long, thick, coarse, pigmented
hair into fine sprouts.
Female pattern
baldness usually begins about age 30, becomes noticeable around
age 40, and may be even more noticeable after menopause. Female
hairloss is usually an overall thinning -- two hairs where five
used to be--rather than a bald area on top of the head, although
women may have a receding hairline, too. It's estimated that about
20 million American women experience such hairloss. Hairloss in
both men and women is again, partly genetic and partly hormonal.
Surgeries, severe
illness, and emotional stress can cause hairloss. The body simply
shuts down production of hair during periods of stress in order
to devote its energies toward repairing vital body structures. In
many cases there is a delay between the actual event and the onset
of hairloss. Furthermore, there can be another long delay prior
to the return of noticeable hair regrowth. This means that the total
hairloss and regrowth cycle can last 6 months or possibly longer
when induced by physical or emotional stress. There are some health
conditions which may go undetected that can contribute to hairloss
-- these include anemia or low blood count and thyroid abnormalities.
Both of these conditions can be detected by a simple, inexpensive
blood test.
Women may experience
some noticeable hairloss in the wake of a major hormonal change.
In most cases though, the condition does not become terribly advanced.
Post pregnancy hormone conditions can be a cause of this type of
hairloss as can discontinuation of birth control pills, menopause
and menstrual cycles. In most cases though, the condition is temporary.
Many women discover that their hair will grow back to its former
luster within a year.
Hairloss may
also occur due to dieting. Franchised diet programs which are designed
or administered under the directions of a physician with prescribed
meals, dietary supplements and vitamin ingestion have become very
popular. Sometimes the client is told that vitamins are a necessary
part of the program to prevent hairloss associated with dieting.
From a dermatologist's standpoint, however, the vitamins cannot
prevent hairloss associated with rapid, significant weight loss.
Furthermore, many of these supplements are high in vitamin A which
can magnify hairloss.
Women can choose
between three accepted forms of treatment. First, you can apply
topical lotions or take oral prescription drugs that have been licensed
by the FDA. Second, you can decide to have a surgical hair replacement
done. There are several surgical procedures to choose from and it
is important to consult with a doctor before making a selection.
The third option is to purchase a non-surgical hair replacement
that covers or adds hair to the thinning portion(s) of her head.
