Major factors of hair loss are known as stress, heredity, and environmental factors, etc. Androgenic alopecia, the most general pattern to both men and women, appears because the follicles are influenced by androgen, is called male pattern hair loss, MPHL by male, and is called female pattern hair loss, FPHL by female. Hair loss is caused by the occasion of exposing to male hormone over the certain period of time. The male hormones of participant of hair growth and atrophy are testosterone and DHT(Dihydrotestosterone). DHT is the products from testosterone, a kind of androgen metabolized by 5α-reductase. Testosterone is reduced to active DHT by 5α-reductase, and the DHT inhibits the growth of hair by combining with androgen receptors which are in the dermal papill cell. Studies were made on the inhibitory effect of culture extract of a wild mountain ginseng to the activity of 5α-reductase in various ways.
