Propecia, how long it takes for it to work?

[GreatSage]

I've been on the so called big 3 for roughly 6 months now, before I started I was hoping by now I would have seen some sort of improvements but unfortunately it seems it has gotten worse which I've read for it to get better the hair loss will be worse off at the start of the treatment.

Anyways, I do plan to keep going with the treatment; maybe for a year? I just wanted to know if anyone has had to wait such long for the treatment to work.
