Kérastase Blond Absolu Masque Ultra Violet Treatment (200ml) is designed to provide exceptional ultraviolet care for decolourised hair. It hydrates sensitised hair, neutralises brassiness, protects hair against oxidation and boosts colour luminosity to give users a shiny finish. The ultraviolet treatment is ideal for lightened and highlighted blonde hair that requires neutralisation, refreshing and restoration. The treatment comes with three unique key ingredients: hyaluronic acid, ultraviolet neutralising pigments and Edelweiss flower. The powerful ultraviolet neutralising pigments are responsible for neutralising as well as removing brassy and yellow undertones from hair to reveal its natural radiant shine. The Edelweiss flower, which is rich in antioxidants, provides maximum protection against hair breakage while softening and calming sensitised hair fibres. The hyaluronic acid, on the other hand, works to refill and heal fibre wounds from within for an even and well-replenished cuticle. For optimal results, apply a sizeable amount of the treatment on freshly washed and towel-dried hair. Massage into lengths and ends and let it sit for 5 minutes if you want light neutralisation or 10 minutes for longer neutralisation. Add water and emulsify before rinsing your hair thoroughly.
