1. I have taken propecia for 8 months, stopped using it, and went back to normal in a week. then tried to take a lower dosage .50 of a pill. had the same side effects.. and still have yet to recover..
2. the first time i quit yes, the 2nd time, still have not yet.
3. could take a week could take 2 months, could be never.
4. search PRP on this forumn, might be something to look into.
5.i guess this would depend on how bad you're hairloss is,age, and what nw scale u are.
