Propecia

Propecia (Finasteride) is the first and only FDA approved oral medication that effectively treats male pattern baldness.  Propecia works my blocking the enzyme 5-alpha reductase type ll which converts testosterone into dihydrotestosterone (DHT). For those genetically predisposed to male pattern hair loss, the hormone DHT miniaturizes susceptible hair follicles causing the hair to progressively become shorter and thinner until it only produces, essentially invisible vellus hair. Early intervention with Propecia has been shown to be extremely effective in slowing or stopping the miniaturization process that leads to male pattern baldness.
