The Kérastase Chroma Absolu Rich Anti-Porosity Masque is a luxuriously creamy deep conditioning treatment specially formulated for medium to thick colour-treated hair that suffers from damage, dryness, and high porosity. Enriched with Lactic Acid and a powerful anti-porosity complex, this 200ml masque works deep within the hair fibre to smooth the cuticle, reinforce internal structure, and seal in vibrant colour so every strand feels silky, resilient, and visibly radiant. With consistent use, it delivers up to 92% stronger hair and preserves up to 92% of colour intensity, transforming dull, porous locks into beautifully nourished hair in as little as 6 weeks. Simply apply generously to freshly shampooed hair, leave for a few minutes to let the rich formula penetrate, then rinse for long-lasting softness, shine, and colour protection that lasts wash after wash.
