Finasteride is a drug that has been intensely researched to be used in the prevention of male pattern hair loss. It's a drug which inhibits the male hormone, and it prevents testosterone turning into DHT or dehydro testosterone. The DHT is the substance which actually causes the hair loss. It settles in the hair follicle and causes the damage. By preventing that transference from testosterone to DHT, you can prevent the hair loss.
