KÉRASTASE Chroma Absolu Anti-Porosity Hair Mask — 6.8 fl oz for Damaged, Color-Treated Hair (Lactic Acid & Amino Repair)

KÉRASTASE Chroma Absolu Anti-Porosity Deep-Filling Hair Mask is a rich treatment designed to strengthen and hydrate damaged, color-treated hair while reducing porosity for improved shine and color longevity.

This intensive 6.8 fl oz mask targets the specific needs of processed hair: it rebuilds weakened fibers, fills porous gaps in the hair strand, and delivers deep hydration without weighing hair down. Formulated with lactic acid (an AHA) and Centella Asiatica alongside amino ingredients, the mask works to reinforce the hair’s internal structure and enhance surface smoothness so color looks fresher and hair feels softer.

How does this mask reduce porosity and why does that matter?

Porosity describes how much moisture hair absorbs and loses; color-treated and damaged hair often becomes porous and dull. The Chroma Absolu mask uses lactic acid to gently re-align and fill porous areas of the cuticle while amino compounds help rebuild internal bonding, resulting in a smoother strand that retains color and moisture better.

• Contains lactic acid (AHA) to fill micro-gaps in the cuticle
• Amino-based ingredients rebuild weakened fiber structure
• Leads to improved color vibrancy and reduced uneven moisture loss

What visible benefits will I notice after using it?

After recommended use you should see softer, shinier hair with fewer signs of frizz and less visible fading of color. The formula targets both surface and internal damage, so hair feels smoother to the touch and looks more reflective under light.

• Enhanced shine and color intensity
• Softer texture from mid-lengths to ends
• Reduced frizz and improved manageability

How should I use the mask for best results?

Use on freshly shampooed, damp hair. Apply an even amount from mid-lengths to ends, leave on for about five minutes, then rinse thoroughly. For maximum color care, pair with Bain Riche Chroma Respect or Riche shampoo and follow the Chroma Absolu regimen as needed.

• Shampoo first with a color-care cleanser
• Distribute mask evenly; focus on damaged and porous areas
• Five-minute leave-in time for everyday maintenance; increase frequency for intensive repair

Is this suitable for all types of color-treated hair?

Yes—the Chroma Absolu formula was developed for a wide range of color processes, from permanent and demi-permanent to highlights and balayage. Its aim is to protect pigment while rebuilding weakened fibers so both subtle and dramatic color services benefit from improved longevity and finish.

• Safe for permanent, semi-permanent, and highlighted hair
• Works on fine to coarse textures without excessive weigh-down
• Complements professional salon color maintenance
