Propecia (finasteride)

This drug is used to promote hair growth and inhibit loss. It inhibits 5-alpha-reductase, interfering with the conversion of testosterone to 5-alpha-dihydrotestosterone. This hormone is referred to as an androgen and results in hair loss, most commonly referred to as male pattern baldness. Your doctor will place you on this to maintain your grafts or as a trial to determine how much hair growth is potentially possible before grafting.
