The shampoo should be sodium chloride(salt) free, some sulfate free shampoos have sodium chloride in them. For some reason there is so much confusion about this from stylists and clients. A shampoo that contains sodium chloride will strip your keratin treatment sooner. Sulfate free is good for color and is more environmentally safe. The only thing you need to look for is a shampoo that does not have the words "sodium chloride" in the ingredients.
