Kerastase Chroma Absolu Anti-Porosity, Deep Filling Masque System, Medium to Thick (16.9 oz) Lock-in Color and Radiance.

If your hair is holding onto color like a leaky sieve holds water, it's time to introduce a heavy-hitter: the Kérastase Chroma Absolu Anti-Porosity Masque. This isn't just a basic hair mask; it's a deeply restorative, anti-porosity "filler" masque specifically engineered for sensitized or damaged medium to thick color-treated hair. Chemical services—even the ones that give you that incredible color—can leave the hair fiber porous, rough, and vulnerable to dulling hard water and color-fade. Our rich, light rose-hued cream penetrates deep into the core of the fiber to truly strengthen and restore its health from the inside out. It’s an indulgence in powerful care, instantly leaving your hair noticeably softer, smoother, and incredibly vibrant with 93% more nourishment.

The secret is the breakthrough multi-repair acid care infused in the Chroma Filler Masque, featuring a potent combination of Amino Acid and Centella Asiatica. Amino Acid, a building block of the hair fiber, works to rebuild and reinforce weak strands deep at the core, boosting resilience against future damage. Centella Asiatica, a regenerative plant widely celebrated in skincare, is incorporated for its soothing and recovery properties. By filling in that tell-tale porosity, the masque transforms the surface of your hair, helping to seal in your brilliant color and protect it from the stripping effects of water during your shower. The result is not just short-term softness, but sustained vibrancy.

Imagine the kind of glossy, healthy, and vibrant shine that only the salon can deliver, now available as an essential part of your weekly regimen. After consistent use, this transformative masque is proven to make your strands 92% stronger and preserve up to 92% of color intensity for six full weeks. It intensely reduces color-induced frizz, restores manageability, and leaves your hair looking and feeling profoundly healthier. This 16.9 oz professional size ensures that your vivid, salon-fresh color remains locked in and intensely bright, giving you that 'just left the chair' confidence day after beautiful day.
