The Kérastase Chroma Absolu Masque Chroma Filler is a deep-filling hair mask specifically designed for color-treated hair. It features lactic acid, which helps to fill porosity and strengthen hair from within, resulting in healthier, softer, and shinier color. This mask is ideal for sensitized or damaged color-treated hair with medium to thick texture. Its indulgent, lightweight rose cream formula penetrates the hair's core to provide 92% stronger strands and helps protect hair from the stripping properties of hard water. Hair becomes 93% more nourished with reduced porosity, leading to longer-lasting color. After 6 weeks, 92% of color intensity is preserved, and hair boasts 62% more brilliant shine. The scent profile includes top notes of Neroli and Cardamom, heart notes of Tuberose, Orange Blossom, and Freesia, and base notes of Sandalwood, Musk, and Guaiac Wood. It works to combat visible effects of chemical damage, such as increased fiber porosity, color-induced frizz, and hair oxidation. Hero ingredient lactic acid gently exfoliates and seals the hair surface to reduce frizz and boost shine, while centella asiatica nourishes. This anti-porosity filling mask is an intensive treatment perfect for your colored hair care routine.
