It is usually triggered by a combination of hormonal activity and heredity, which together cause the hair follicles in your scalp to shrink.Over time, the progressive shrinking of certain scalp follicles leads to a shortening of the hair\'s growing cycle. Hair becomes thinner and shorter, until there is no growth at all. The active ingredient in ROGAINE--minoxidil--reinvigorates shrunken hair follicles, which increases their size and helps regrow thicker looking hair over time.A Pioneer in Hair RegrowthLike many great discoveries, the power of minoxidil to regrow hair came about by chance. In the 1980s, scientists discovered that minoxidil, being studied for other indications, actually showed signs of regrowing hair.ROGAINE applied this discovery to produce the first topical brand approved by the FDA to regrow hair. Minoxidil is the only over-the-counter ingredient FDA approved to regrow hair. Since the discovery, ROGAINE has empowered millions of people to take control of their hair loss with a series of breakthroughs.About ROGAINE: A History of Results and InnovationROGAINE is the first topical brand approved by the FDA to regrow hair--in both men and women.
