My hair doesn't like a lot of protein. It seems to take better to conditioners that don't have any like Suave's version of Biolage; however, I do all right with cholesterol treatments, but not with products that list wheat protein/wheat amino acids and such. I can follow these products with something moisturizing, but my hair still feels too stiff and hard for a long time afterwards like when I used mane n'tail conditioner (bad move). I've even noticed that some serums and styling products have protein. I stay away from those because I always get bad results. Anybody else?
