Is it true that Regaine should only be used on the crown area of the head? I know it shouldnt be used on the front hairline but what about the top middle area?Testing the meds for the first two months is basically checking for side effects. Most patients do not see any signs of growth at this stage. If no sides, then give it 6+months to see if it's holding onto your native hairs and possibly regrow and thicken miniaturized hairs. I heard patients say with Rogaine use, they may see some shedding at the beginning but they end up seeing those hairs come back.
