PROPECIA MECHANISM

"Propecia works by inhibiting the conversion of testosterone to DHT (dihydro-testosterone)," said Keith Kaufman, M.D., senior director of clinical research at Merck Research Laboratories in Rahway, N.J. "It is the first treatment to target this key factor in the development of androgenetic alopecia in those patients genetically predisposed."
Researchers believe male pattern hair loss is due to heredity. It is dependent on a hormone called dihydrote- stosterone (DHT). DHT causes to a shortening of the growth phase and a thinning of the hair.
When high levels of these naturally occurring hormone are present in the scalps of men it genetically disposed to Male Pattern Hair Loss.
An important enzyme involved in regulating the hair follicle. PROPECIA blocks 5 alpha-reductase (enzyme), reducing the level of hormone, DHT, in the scalp and allows hairs to revert to a normal growth cycle. This results in no further hair loss and significantly new hair growth in men.
