MALE PATTERN BALDNESS

male-pattern baldness

The typical pattern of baldness in males in which the baldness begins in the frontal area and proceeds until only a horseshoe area of hair remains in the back and at the temples. It is due to testosterone, but genetic predisposition is also a factor. Baldness does not usually occur in males having no familial tendency to become bald. Minoxidil or finasteride has helped stimulate growth of hair in some individuals. Synonym: male-pattern alopecia See: illustration
