When I looked at the ingredient on the box I realized that it contained a lot of what was already on my counter. This worked for me because I could take one pill instead of several.
I've only used it for a month and am not sure I can say it's done anything for my hair. I can say that my hairdresser commended me on how healthy my hair was, didn't have to clip my ends and fully endoresed Aphogee products. I'm actually gonna attempt to find these at my local drug store. The shipping on this product is a bit much.
