Dyeing or bleaching processes weaken hair's natural structure, making it less protected against stress from artificial heat, pollution, UV rays, chlorine or sea salt. Over time, this causes hair color to fade and oxidize, resulting in undesirable color tones. The 'Color Shield Mask' specifically helps against this - it delivers a powerful combination of antioxidant vitamins that protect the hair color from oxidative stress and sustainably strengthen the hair fiber. The high concentration of macadamia oil, rich in Omega-9, helps to deeply nourish and restore the hair fiber damaged by successive coloring processes. Application For effective results, use Color Shield Shampoo first, followed by the mask. Apply evenly to wet hair and massage gently from roots to ends. Leave on for 3 to 5 minutes and rinse thoroughly. Result The acidic pH value pulls the hair cuticle together and thus binds the color pigments additionally in the hair core and improves the color intensity. The hair colour appears particularly shimmering, especially radiant and has a unique glossy finish; as radiant as on the first day of colouring.
