Hair coloring and bleaching require special care and hydration to maintain an intense color and shine as long as possible. Hair is vulnerable to very aggressive shampoo, the sun and wind factors that cause color loss. SHAMPOO POST COLOR is formulated especially for colored (chemically treated) hair. Its low pH helps to close the cuticle after chemical processes, prolonging tonality and vibrancy. It protects against environmental elements and contains neutral pigment to help maintain high pigment density in hair, ensuring shine and vitality. It maintains bright color from root to shaft end.
