Formulated with powerful neutralising purple pigments, Kérastase Blond Absolu Masque Ultra Violet Treatment has been designed to give cool blondes and highlighted or lightened hair colour extra luminosity and radiance. The mask repairs hair whilst effectively eliminating orange, yellow and brassy tones that are often found in blondes. This reparative treatment not only illuminates and brightens lighter shades but also rebuilds and revives the hair fibre by strengthening and protecting locks. Its vibrant purple non-staining colour cancels out unwanted warmer tones whilst defending against damaging oxidisation which can occur in coloured hair. The high concentration of violet falls on the opposite side of the colour spectrum to yellow, efficaciously cooling and brightening blonde shades. Also enriched with a highly concentrated blend of Hyaluronic Acid, the mask fortifies the hair and helps prevent any breakage. Whilst deeply conditioning the hair, the potent antioxidant properties of Edelweiss Flower defend against damaging environmental factors and help soften any brittle strands. Apply to freshly washed and towel-dried hair, massaging in and leaving on for 5-10 minutes depending on the intensity of neutralisation needed. Rinse off thoroughly before styling hair.
