I've watched this thread for a while now and I see most people say they can't tell if it's working for hair but notice differences elsewhere. I've noticed a slight difference in my hair. I haven't had any unwanted facial hair. I started off with 2 a day and half way through the first bottle I upped to twice a day. At first I got a few pimples when I upped to twice a day but by the end of the first bottle they went away. Probably just needed to adjust. My nails are growing faster and my hair is shinier. I also notice more length faster in the front. The rest of my hair seems to be growing normally. On the end of my second bottle. But this one was much larger than the first and I got it from Target.
