Tried the no sulphate thing, I'm not convinced it's any better for me. Latest one was loreal hydrapure, purple and green bottle. Supposed to be for oily roots and drier ends. Hair is oily again overnight. Worse than ever and have to shampoo daily with this. I can't understand it. Sulphates, no sulphates, you used to just pick a bottle for oily hair and be done with it. Nowadays it's so confusing. Any recommendations for something I can easily pick up and not costing a fortune?
