Topical minoxidil in the treatment of male pattern alopecia.
Male pattern hair loss (androgenetic alopecia) is a common problem. In fact, it affects nearly all males to some degree. Expression of the disorder is variable, and while it is never life-threatening, it often becomes a major source of consternation. The biology of the process is poorly understood, and no current therapy can halt or reverse the process. Only cosmetic surgery, which is painful, time consuming, and expensive, has been effective. In the past 7 years, since it was noted that a patient taking minoxidil for hypertension had reversal of male pattern hair loss, awareness of a possible therapeutic role for topical minoxidil in the management of this disorder has grown among physicians, scientists, and the general public. It can be concluded from available data that topical application of minoxidil is effective in providing cosmetically satisfying thickening of hair in a select group of individuals with male pattern hair loss. The drug's mechanism of action remains obscure. No serious side effects have been demonstrated with its use, however, and it is therefore advised in selected patients.
