Oct 29, 2009 - While this worked great for my hair it did horrible things to my scalp. I think I am allergic to one of the ingredients. I switched to the Jessicurl cleansing cream and the problem cleared right up. My stylist, who specializes in curly hair, has had other clients complain of similar reactions to the Devacurl no-poo. I have had no problems with any of the other Devacurl products.
