I am 22 years old and it appears that I have been losing more and more hair every day. If I go on the drug Propecia, how long will it take for the drug to stop the hair loss.
Responses from finasteride vary with the individual. I have seen some people stop their hair loss in a week from starting the medication, and other take a couple of months. You need to make the decision to continue using it from the time you start taking it. The full benefits could take up to a year.
