This 100% clean, sulfate-free, residue-free formulation is perfect for all curl types. Hooked envelops curls with a special Procapil blend that helps anchor hair at the root, thereby preventing excessive shedding and breakage. The particularly gentle formulation of the shampoo not only removes buildup from styling products but, unlike many other shampoos, contains only ingredients that rinse out easily. Hair and scalp are left clean and in optimal condition. Application: Apply to wet hair and massage until it lathers. Rinse thoroughly and repeat. If a rich lather does not form, the hair may be heavily soiled and may require a third wash.
