I wanted to ask a question. It's known that propecia can regrow some hair and if you stop taking it, you loose these hair. But if you take propecia for a long time, you'll prevent a lot of hair from thinning and falling. So my question is, if you stop propecia after several years, do you think you loose all the new hair that have regrown AND the hair you kept or you just loose the hair that came back after taking propecia.
