I tried using this stuff as general purpose shampoo and it destroyed my hair. I was only washing my hair once every two weeks (natural oils, you know) and I thought it'd be good to clear up the scalp of extra oils but instead it sucked me dry.
Hmmmmmmmmmmmmmmmmmmm, I think I used it like normal shampoo. To be fair, my hair would be decently oily by that point.
