I'm really sad that I have to give this product a low score, because at first I really enjoyed it and it was doing wonders for my hair! but I noticed after a few uses it caused a grease spot on the back of my head! I didn't want to believe it was this product, but when I switched shampoos it went away. lately I decided to give it a try again, and yet again, a grease spot. I feel it did help my hair strengthen and grow some, but its not worth the side effect it has on my hair. maybe this doesn't happen to everyone though, so if you still want to give it a try it is at a good value and can be found at most grocery stores and drug stores.
