Advice....

[bb37]

I'm 37 and have been on Propecia for about 1.5 years. It was working great during that time. I didn't see regrowth but the thinning/shedding seemed to stop. Recently I've noticed that the top is thinning again. A lot. I used to have seriously thick hair. Is this normal? Will the shedding stop again? Does rogain work on the top of the head? I've never used it and heard that Rogain actually caused more shedding. Any Advice?
