Hair loss usually develops gradually and may be patchy or all
over (diffuse). You lose roughly 100 hairs from your head every
day. The average scalp contains about 100,000 hairs. Each individual
hair survives for an average of 4 1/2 years, during which time
it grows about 1/2 inch a month. Usually in its 5th year, the
hair falls out and is replaced within 6 months by a new one. Genetic
baldness is caused by the body's failure to produce new hairs
and not by excessive hair loss . . .

Did you know that the average person has 5 million hairs? Hair
grows all over your body except on your lips, palms and the soles
of your feet. It takes about four months for healthy hair to grow
an inch. Most hairs grow for up to six years and then fall out.
New hairs grow in their place. Men - and some women - lose hair
as they grow older. You can also lose your hair if you have certain
diseases, such as thyroid problems, diabetes or lupus. If you
take certain medicines or have chemotherapy for cancer, you may
also lose your hair. Other causes are a low protein diet, a family
history or poor nutrition . . .

Patterns of hair loss
One of the commonest forms of hair loss in women (and men) is
a condition called telogen effluvium, in which there is a diffuse
(or widely spread out) shedding of hairs around the scalp and
elsewhere on the body. This is usually a reaction to intense stress
on the body's physical or hormonal systems, or as a reaction to
medication . . .

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 . . .

Loss & Hair Restoration
People who notice hair falling out, thinning, or appearing in
large amounts on their comb or brush should consult a dermatologist.
With correct diagnosis, many people with hair loss can be helped.
A dermatologist will evaluate a patient's hair-loss problem to
find the cause so they can determine whether the problem will
resolve on its own or medical treatment is needed . . .

Loss - Cause, Prevention and Treatment
By Kyle J Norton
The adult
scalp contains about 100,000 hair follicles. Everyday the scalp loses
about 100 hairs and they will grow back in 5-6 weeks.
Starting
at age 40, the levels of by-product prolactin of testosterone of men increases,
stimulating the production of the enzyme 5-alpha reductase that causes
the conversion of testosterone to gihydro-testosterones DHT causing our
hair to grow back thinner or not grown back at all.
This causes
an androgenic alopecia hair loss problem, since DHT shrinks the follicles
causing hair thins and hair receding at the forehead, crown and temple
for men and thins over the entire scalp for women.
