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
Medical Dictionary, © 2009 Farlex and Partners


Premature hair loss. Male baldness is common and is thought to be due to an AUTOSOMAL gene that behaves in a DOMINANT manner in males and in a RECESSIVE MANNER in females. This is called a sex-influenced trait. See also ALOPECIA.
