Questions before i start on propecia

[optimisticyouth]

Hello everyone, long time lurker here. I am 20 yrs old and believe that I may be thinning up top. I'm going to see a hair transplant doctor this Friday to be evaluated. Anyway, I have a few questions for the finasteride users on this board.

I've come across the term "reflex hyperandrogenism" quite a few times. From what I could discern, it appears this is what happens to people whose mpb speeds up while on finasteride. My question is how common is this? How long was your shed and at what point did it stop?
