Synopsis L'Oréal Professionnel Paris's Blondifier Mask is an intense-care product that revitalizes and nourishes blonde, highlighted, and bleached hair. The mask gives the hair intense moisture, calms the surface of the hair follicle, and enhances brightness because it contains açai berry extract. Essential nutrients make hair more manageable and add shine and suppleness. Application: Massage into towel-dried, clean hair. Turn it on for three to five minutes. Give it a good rinse.
