Male pattern baldness and its management: an update.

Androgenetic alopecia (AGA) sometimes referred to as `male pattern baldness' (MPB) may affect up to 50% of males between the ages of 30 and 50 years. The authors of this article review the medical and surgical approaches currently available to treat AGA. Medications, such as topical minoxidil, which are currently being marketed as a treatment for AGA, as well as other drugs currently under investigation are examined. Recent advances in punch hair transplantation, alopecia reductions, and flap surgery are also discussed.
