Medications serve are important role in both the prevention & treatment of hair loss, particularly in the early stages of the balding process. The FDA approved medication Finasteride which inhibits DHT is particularly helpful in reversing genetic baldness in its early stages. Minoxidil can sometimes be useful for early loss by stimulating hair growth. But it is more effective when used in conjunction with Propecia. Medical therapy works to thicken hair in areas that are thinning, rather than to grow hair once it is lost.
