This conditioner aims to nourish dry hair, where often the effects of even good shampoos are less visible. A conditioner rich in oils and vitamins is essential in order to hydrate the hair and to maintain the action of the keratin treatments. My Pro-Keratin Conditioner is indicated for dry, treated and damaged hair subjected to aggressive chemicals in perms or straightening. Avocado and silk extracts revitalize hair, giving it volume and softness. Hair becomes brighter and easier to handle.
