Fortnightly Review: Male Pattern Androgenetic Alopecia

Male pattern androgenetic alopecia is a common type of hair loss in men caused by genetics and hormones. It affects 30% of white men by age 30 and 50% by age 50. Effective treatments include topical minoxidil and oral finasteride, but there is no cure. Hair transplantation surgery may also be an option. It is important to manage patient expectations and provide emotional support. New treatments, such as inhibitors and gene therapy, are in development.
