This gel-in-cream hair mask deeply strengthens the fibre structure to reconstruct and hydrate post-lightened blonde hair. It intensely hydrates and plumps fibre for a stronger look and feel. Hyaluronic Acids Duo and Edelweiss Oil enhances fibre resilience to prevent future breakage and split ends, making the hair more manageable and easier to detangle. This Kérastase deep conditioning hair mask is suitable for over-processed and very sensitized blonde or coloured hair. The Masque Cicaextreme reduces post-lightened hair porosity and seals open scales for a uniform healthier fibre.
