I have been on Propecia 1mg for 1 1/2 years with no side effects. I had to go off to get my hormone levels checked because of high testosterone which I think is from Propecia. My doctor wants me off for three weeks and I am concerned I may loose hair in that time frame. Will I be able to get back on without loosing hair? And I was thinking of starting out with 1/2 dose of Propecia which is 0.5mg. Anyone with the same experience? its already been 14 days and noticed around 7 hairs in the shower while on Propecia i have 0 hairs in shower.
