Blue: Since you ordered me to answer this question, I guess I have no choice :shock:
I have been on it over 6 months, and I first noticed some thickening and some regrowth around 3 months. I am NOT on anything else.
Things seemed to have stayed the same for a couple three months, and now, around month 6th, it looks like I am again going thru a positive growth phase...more thickening on the crown, and more regrowth. I looked hard with a mirror the other day, my hair is very short, buzz cut, and I'll be damned if it wasn't starting to look like it did when I was 21, again.
