    Not enough evidence yet

    I have used this product before and then stopped but have gone back to it. Not because I tried other products in between, I just didn't.

    I haven't used it log enough to have an opinion yet. I haven't seen results yet. For this reason that category only gets 1.

    Price wise, it's affordable enough to keep trying and give it the recommended time.

    I don't like the fact that my sculp is flaky after. I don't want to be washing my hair every day after use.

    My ultimate goal is to stop my hair from falling out so much. This is for hair growth, but my hair grows, it just falls out - a lot and I don't know if this product will help.
