I cannot use sodium laurel sulfate or sodium laureth sulfate- I have a sensitive scalp. I am always on the lookout for great SLS free shampoos that really work, but this is not really one of them. I like the mint scent, but it does not clean my hair even with two latherings! This formula also does not create lather as well as the other 365 shampoos. After drying my hair does not look clean or feel clean, but smells good. Just not good enough. All in all, I was disappointed in this one and I would not recommend.
