What
Are The Causes of Hair Loss?
Understanding the cause of hair loss may better indicate exactly why
it presently has no cure.
Androgenetic
Alopecia -- the modern medical tern for either male or female pattern
hair loss -- can be broken down in two parts. First, Androgenetic, consisting
of ANDROGEN (Any of the various hormones that control the appearance
and development of masculine characteristics such as testosterone).
And GENETIC -- the inheritance of genes from either the mother or the
father's side of the family. Add AGE, which when coupled with genetics,
represents a time clock that will signal the hair follicle to produce
an enzyme name 5 alpha reductase. When the testosterone present in the
follicle combines with the enzyme 5 (DHT). Hair follicle receptors are
sensitive to DHT and thereby start the process of male or female patter
hair loss. Second, Alopecia meaning hair loss of which there are many
types.
Put simply, scientists are
working against aging, hormones and genetics. This is no easy task.
Add the fact that male or female pattern hair loss is not life threatening,
and it is easy to see why many physicians do not view hair loss as a
priority in scientific research.
What is working for you
in terms of research is that large pharmaceutical firms now know that
a cure for hair loss could mean a fortune in revenue for their companies
and stockholders. This is fuel enough and the race has begun.
Although we may not see
a cure in our lifetime, it is possible. Science is closer to understanding
hair loss due to many recent advancements. To say the cure is around
the corner would only be speculation but hope certainly is alive.
Other
Causes
Alopecia Areata --
Generally thought to be an autoimmune disorder. Cause "patchy" hair
loss, often in small circular areas in different areas of the scalp.
Alopecia
Totalis -- Total hair loss of the scalp, (an advanced form of alopecia
areata).
Alopecia Universalis -- hair loss of the entire body, (also an advanced form of alopecia
areata).
Traction Alopecia -- Hair loss caused by physical stress and tension on the hair such
as prolonged use of hair weaving, corn rows etc. Done too tightly on
weak hair these can cause permanent hair loss.
Telogen Effluvium -- usually temporary hair loss. Causes: Physical stress -- emotional
stress -- thyroid abnormalities- medications and hormonal causes normally
associated with females.
Anagen Effluvium -- Generally due to internally administered medications, such as chemotherapy
agents, that poison the growing hair follicle. All of these represent
only a few of the different types of hair loss. Androgenetic alopecia
represents close to 95% of all hair loss however.
Hair loss:
true or false?
If your father has a full head of hair, you won't go bald
False
A tendency to baldness is inherited and probably involves
a combination of genes. So you are not automatically in the clear even
if your father has a full head of hair. It is not true, as sometimes
claimed, that only genes from the mother's side are involved.
Brushing the hair 100 times a day will stimulate
the circulation and prevent hair loss -
False
Vigorous brushing is more likely to injure the hairs
and make the problem worse.
Some hairstyles, like braiding can cause hair
loss
True
Styles that pull or put tension on the hairs - such as
tight ponytails or corn-rows - can cause hair loss.
Hats encourage hair loss because the hair can't
breathe
False
Hair
does not need to breathe. Only the root of the hair is alive, and this
gets its oxygen from the blood in the scalp.
Frequent shampooing makes hair fall out
False
The 50-100 hairs we lose each day often become tangled
with the rest of the hair, but are washed out when we shampoo. So we
see what seems like a lot of hair in the shower after shampooing, but
in reality these hairs have been shed earlier.
Blow-drying can worsen hair loss
True
The reason is that extreme heat damages the proteins
in the hairs, making them fragile and liable to break off. Brushing
the hair during blow-drying causes more damage. If you use a hair dryer
it should be set on the coolest setting.
Hair coloring, perm solutions and hairsprays
worsen hair loss
False
Hair dyes, perms and hairsprays do not affect thinning
hair. Perms and hairsprays can help to disguise the problem. Remember,
it is the follicle, which is located beneath the skin, that produces
the hair. Chemical treatments can damage the hair strands but can't
affect the follicle.
Baldness
can be linked to heart attacks
Inconclusive
In 1999, doctors at Harvard Medical School found that men who had lost
hair at the crown of the head had a 32% increased chance of coronary
heart disease. Hair loss at the front of the head hardly increased the
risk at all. Regardless of how accurate this study could be, if you
have baldness at the top of your head, you should stop smoking, eat
healthy, have your blood pressure checked and do some exercise.
