Kerotin hair growth formula

This hair growth formula works OK, does make hair grow faster and your nails. Helps hair become stronger and less fall out. I haven't noticed any real thickening yet I'm just starting my second bottle though. I have used other vitamins for hair growth and I do so far like this one the best. Has more hair growth ingredients compared to others. It's a little bit up there in price though. I believe I paid $65 or a little more.
