Male And Female Baldness Essay, Research Paper


Baldness is the partial or total absence to; hair in the scalp. Some


thinning of the scalp hair take place as a normal part of the process


of aging. However, many types of abnormal hair loss also occur. Some


kinds of baldness involve only a thinning of the hakr from one small


area of the scalp. But in the most common type, called male pattern


baldness, a man loses much or all of the hair over the top of the


head. A smaller number of women have a comdition known as female


pattern baldness, which involves thinning of the hair but usually not


complete baldness. A healthy scalp sheds old hairs continually, and


new ones grow to replace them. Baldness develops when new hair stops


growing for any reason. In male pattern baldness, hair loss results


from the combination of an ingerited trait and the effects of the


hormone testoterone. Loss of hair may begin duting the teen-age years


or at any later time. Pattern baldness cannot be cured. However,many


types of baldness are timporary, and normal hair growth cannot be a


symptom of many serious illnesses, of a skin

infection, or of emotional


stress. The use of certain drugs may also cause temporary baldness.


In male pattern baldness, heredity strongly influences the degeree of


hair loss and the age at which it begins. A man can ingerit baldness


from either hes father or hes mother. The exact pattern of influence


is not known. The percentage of men who have male pattern baldness


increaseswith age. People may use any of several methods to cover bald


areas. Many wear a hairpiece, such as a toupee or a wig. Others


prefer hair, wearing, a technique in which the sides of a hairpiece are


served into the remaining hair. In a process called hair tranplanting,


a doctor surgically, removes plugs of the scalp that contain growing


hair. The plugs are then transplanted to the bald areas. In addition,


clinical trials have ahown that treatment with a special drug


stimulates hair growth in some individuals with baldness. This drug,


which has the trade name ^Rogaine^, was approved in 1988 by the Food


and Drug Administration (FDA) for treatment of baldness. It must be


applied to the scalp twice daily to maintain hair growth.
