I'm using this particular shampoo & a few other products to help my hair grow. I truly do feel as though this shampoo is the leading factor to my growth & thickness. I noticed a difference after about a week & a half of using. & I only use it every other wash.
It helps your hair become fuller by strengthening each strand. By making your hair healthier, you are able to grow longer hair! I have used if for about a year and a half now, and it seems to help my hair grow faster.
