It’s been a year using Proscar, and I don’t see it working on my hair

I currently have been taking proscar for 9 months and have still been thinning out. Im confused as to wait a year, when it hasn’t been working? Some people even say 2 years?. I guess what I am asking is how likely is it that I’m just a late responder ?

The drug finasteride (Proscar., Propecia) takes time to work. A year minimum, For young men, it is patience that you need. Sometimes it looks like it is not working but it may be slowing down the hair loss and without it, it might fall out faster
