Rogaine (minoxidil) This was the first hair growth drug approved by the FDA. Now it’s available without a prescription – extra strength for men and regular for women. Rogaine’s effectiveness is established in front and back for women but only in back (vertex) for men.
Rogaine seems to work because of its vasodilator properties. DHT shrinks and chokes follicles, and Rogaine seems to combat this by swelling the follicle’s tiny microvascular structures. This is not to be confused with a generalized increase in circulation to the scalp – a premise of many scams.
