Deliver salon-worthy shine to your blonde tresses with Kérastase Blond Absolu Masque Ultra Violet Treatment. This luxurious weekly hair mask restores lightened and highlighted tresses with its deeply nourishing formula. The purple mask works to eradicate yellow and to neutralise brassy tones in blonde locks whilst maintaining shine, keeping your blonde hair light, cool and radiant. Kérastase Blond Absolu Masque Ultra Violet Treatment defends against dullness caused by pollution and other environmental aggressors whilst adding moisture to frazzled locks. Enriched with Hyaluronic Acid, hair will appear thicker and your scalp will feel nourished with smooth and shiny strands. The added natural element of Edelweiss Flower protects hair from harmful UV rays and helps to rebuild hair fibres, resulting in a mane that is damage free and feels fuller and healthier. This weekly treatment has been developed with lightened and highlighted hair in mind, protecting vulnerable colour-treated hair from harsh toxins which can tarnish tone and damage follicles. Massage into washed and towel-dried hair and leave for 5-10 minutes before washing off to reveal cool and restored locks.
