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 your 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 affect 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 receding 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 lose 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 diagnose 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.
