Finasteride

Finasteride is available only by prescription and is taken orally daily. It is marketed under the brand name is Propecia®. Its mode of action is well understood thanks to research that documented the hormonal cause of hair loss in androgenic alopecia. Finasteride inhibits the enzyme that converts testosterone to dihydrotestosterone (the dreaded DHT everyone with hair loss is ware of) in the follicle. Finasteride has proven highly effective in clinical trials and in medical practice for slowing hair loss in almost all men and stimulating new hair growth in some men. It can be used alone or in conjunction with other hair loss treatments, including surgery.
