(We are supposed to take the pill!!!!!)
Minoxidil was approved in a lotion to help regrow lost hair for men in 1988, and for women in 1992. It works by using enzymes present in hair follicles to break the drug down into an active form which stimulates the growth of new hairs. But it must reach the scalp to work — which is often stopped by remaining hairs — and patients often dislike leaving it on their heads for at least four hours every day.
Doctors have found, however, that when the drug is taken orally as a pill it is still broken down into the active form that triggers hair re-growth. The discovery was first made by Dr Rodney Sinclair, a dermatologist at the University of Melbourne, Australia, when he had a female patient suffering from pattern baldness who swore by Rogaine but started suffering an allergic rash to the lotion.
