Meh, this isn't all that great of a product. I've been using it for probably 2 months now and I only have 1/4 of the bottle left, I'm just trying to use it up. It really doesn't protect as much as others that I've tried before, but it's not too bad. At least it doesn't have alcohol in it, which is what prompted me to buy it. And also, there is a small trace of biotin, which keeps hair strong. But I haven't noticed a change in my hair at all.
