Personally, I think that some hair just responds better to sulfates. However, it took me a long time to realize this. I tried the curly girl thing, I tried the sulfate free thing and I didn't use cheap products...I bought the entire Jessicurl line and when that didn't work tried the entire devacurl line. I was determined to make these products work. Devacurl worked at first, but after a while my hair got weighted down. While I loved the scent of Jessicurl products the oils were too much for my hair and my hair always got cotton ball frizz. I do better with a sulfate shampoo 3 times a week. My hair looks so much better now. It's all about finding a balance of what works for you. Good Luck!
