I started using Propecia on Aug 1, almost exactly 3 months ago. I started noticing about a week ago that I am shedding more than usual. I know this is not abnormal, but was wondering how long the shedding period usually lasts? And is it true that shedding at 3 months means the Propecia "is working", or is that wishful thinking coming from people who are going through the shed? THANKS!
