Does rogaine (minoxidil) stop hair loss or does it grow new hairs?

Both. Rogaine (minoxidil) increases the effectively blood flow to the hair follicle. The increased blood flow can stabilize further hair loss and also allows some dormant follicles to resume growth. Rogaine (minoxidil) works best to regrow hair on the vertex of the scalp.
