I did my first CO today. I've been using Nature's Gate Biotin Shampoo and Conditioner, but I was disapointed to learn that the shampoo has SLS in itand I'm pretty sure that SLS makes me shed a whole lot and gives me scalp itches. I really should have read the bottle better Since I didn't want to chuck them, I decided to use the 'poo for shaving and just use the condish for CO. I'm REALLY liking the results! My hair is very soft and thick I think I'm hooked!
