I'm 24 years old, and have been losing hair rapidly for a couple of years or so. A couple of months ago, I buzzed my hair real short (like size 1), and I used rogaine 5% for about 2 weeks. It really irritated my scalp though, and I also got bad headaches from it. So I stopped using it after 2 weeks, but then immediately I started noticing some shedding which has gone on for 2 months now -- and my hair is definitely thinner than when I started.
My question is -- can I expect this hair to come back without using rogaine again? I've heard that rogaine pushes follicles into the dormant phase, hence the shedding, so can I expect to go back to a similar level to before when I started rogaine? Or is it a lost cause?
