How does Propecia work?
Researchers have recently discovered that men who suffer from male pattern hair loss have increased levels of dihydrotestosterone (DHT). DHT is produced from testosterone through the activity of an enzyme called 5-alpha-reductase. Biochemical analysis reveals elevated levels of 5-alpha-reductase in the scalp of balding men and the lack of the hair loss in men with 5-alpha-reductase deficiencies. Propecia inhibits 5-alpha-reductase, thus blocking the formation of DHT. This appears to interrupt a key element in the development of male pattern hair loss.
