Contrary to popular belief, these shampoos and conditioners are not just for people who've had the Keratin smoothing treatment (otherwise known as "Brazilian" keratin treatment). Coppola's Keratin Complex have a wide range of shampoos and conditioners to meet different hair needs. The main reason that these products work is that they contain natural Keratin protein, a substance found in human hair. Keratin is stripped out of hair over time due to over-processing, age, and being exposed to the earth's natural elements. Another culprit in stripping your hair of this natural protein is Sodium Chloride, which is found in many shampoos. Coppola's Keratin Care Shampoo does not contain Sodium Chloride. Their Keratin Color Care Shampoo contains no Sodium Chloride, and no sulfates, so hair will not be stripped of its natural keratin or its color.
Their conditioners also contain wheat and soy proteins which help protect hair from the elements, while detangling and leaving it soft and manageable.
These products can be used on many different hair types, but are especially effective on curly hair, and those who have chemically processed hair.
