Professional amphoteric shampoo. Special shampoo with pH 5.5 for color-treated hair. The shampoo is specially formulated with sulfate-free surfactants to balance and gently cleanse color-treated hair. The cleansing action does not change the physiological balance of the hair and scalp and does not affect cosmetic color pigments. With a special formula of balancing and gentle cleansing action, the hair and scalp are resplendent, retaining rich color and highlights for a long time. Distribute the product well on the scalp and hair. Let it clear by gently massaging the scalp in a circular motion with your fingertips, rinse off. Repeat the procedure, if necessary, leaving the shampoo for a few minutes and rinse.
