Can Propecia Bring Me From a Norwood Class 3 to a 2?

I read Propecia doesn’t help with temporal recession and receding hairlines but I’m on a NW2 right now and it looks like I’m heading to a NW3, can Propecia prevent that from happening? And it seems I’m now a little more then a NW2 do you think Propecia can help me go back to a solid NW2?

It is possible, though full regrowth in the hairline is rare — at least more rare than regrowth in the crown/top of the head. At the very least, Propecia should halt the progressive hair loss for some time so that you can retain what you have now.
