Balding is a problem that both men and women alike dread. There

is nothing you can really do to stop it from happening. Each day you loss

up to fifty hairs. They are replaced with new ones, but in balding people

the hair stops coming back. Probably the most common cause of baldness

is the use of antineoplastic drugs.



Baldness is also known as alopecia. Alopecia is much more

common in men than women. Approximately forty percent of all

men have hair loss. Hair loss can result from many things, such as

genetic factors, aging, drugs, diet, local skin conditions and diseases that

effect the body generally.



The most common type of hair loss that affects men is male

pattern baldness or MPB. This really depends on the male

hormones called androgens within the hair follicle which are at high

levels after puberty.



Baldness is genetic, so it does run in the family. Hair loss usually

starts on the sides near the front or on the top of the head, towards

the back.



Hair loss can begin at any age, even in the middle teen years. If

you have hair loss this early in life you may go completely bald

later in life. Some people only loose some hair and have a bald

spot in the back of their head and others have a receeding hairline.



You can also have hair loss if you have a severe illness with a high

fever. This is called toxic baldness or toxic alopecia. Taking

excessive doses of some drugs like thallium, vitamin A and

retinoids can also cause hair loss. Hair loss can also result from an

underactive thyroid gland or pituitary gland or even pregnancy.

The hair may fall out as long as three or four months after the

illness. The hair loss is temporary.



In some cases people loss their hair suddenly in a particular area.

Such as in the scalp, beard, axillae, pubic area, arms, and legs.

This is called alopecia areata. The hair usually grows back in

several months.


Hair loss in scarred areas is called scarring alopecia. The skin may

be scarred from burns, severe injury or x-ray therapy.Hair has trouble

growing in these places because of all of the scarred tissue.



The type of baldness is very difficult to diagnosis by observation.

A biopsy may be necessary to help the physician properly

diagnosis the type of baldness. Most types of baldness have no

cure. Some types may undergo a hair transplant, in which hair

follicles are removed from one part of the body and transplanted to

the head. Also, there are a number of medications to help a certain

amount of people to regrow hair. People with alopecia areata can

be injected with corticosteroids under the skin. This may help in

the regrowth of hair, but the results may not last. Another

treatment for this type of baldness is to actually induce a mild

allergic reaction or irritation to promote hair growth.

Unfortunately, those with scarring alopecia, even when the scars

have healed, are highly unlikely to regrow hair in that area since

the tissue has been scarred.
