1 year minimum... 2 years (for me) was when I noticed good results.
Didn't really lose ground along the way, even after a year. Didn't really get better.Did you lose ground before getting results? im now on my 7/8 month and im losing hair, it was just my crown that was the problem now im diffuse thinning over the top of my head aswell. Thinking of switching to dutasteride.
