KÉRASTASE Chroma Absolu Hair Serum for Color-Treated Hair — 5.1 fl oz, Heat Protection & Anti-Frizz

KÉRASTASE Chroma Absolu Hair Serum is a leave-in smoothing serum that moisturizes color-treated hair, tames frizz, and protects against heat up to 450°F for longer-lasting, shiny color. KÉRASTASE Chroma Absolu Hair Serum is designed specifically for chemically treated and color-treated hair that needs moisture, protection and manageability. This lightweight, non-rinse spray delivers conditioning agents and heat defense while reducing porosity so color looks brighter and hair feels softer after styling. Use it on damp, towel-dried hair before air-drying or blow-drying to help prevent breakage and minimize frizz from daily styling and environmental stressors.

How does this serum protect color-treated hair during styling?

The formula reduces porosity and builds a light protective layer on the hair fiber that helps guard against color fading during heat styling. It contains ingredients that reinforce weakened strands so the hair can better withstand thermal tools and mechanical stress.

• Heat protection rated up to 450°F to shield hair during blow-drying and flat-ironing
• Porosity reduction to slow color washout and prolong vibrancy
• Lightweight finish that won’t weigh down fine or processed hair

What smoothing and moisturizing benefits will I notice?

The serum targets frizz and dryness commonly seen after color services by delivering deep hydration and restoring surface softness. Hair looks glossier and feels smoother immediately after application and styling.

• Moisturizing agents that replenish dryness from bleaching or coloring
• Frizz control for a sleeker, more polished appearance
• Visible shine improvement for color-treated strands

Which active ingredients help rebuild fragile color-treated hair?

The product includes targeted actives that support the hair’s structural integrity and scalp-to-tip health without heavy residues. These ingredients work together to strengthen the fiber and protect against further weakening from styling.

• Lactic Acid (an AHA) to smooth and help renew the hair surface
• Centella Asiatica extract to support resilience and reinforce fragile fibers
• Vitamin E for antioxidant support and improved hair feel

How should I use the Chroma Absolu Hair Serum for best results?

Apply to towel-dried hair for optimal absorption, then distribute evenly and style as usual—no rinse required. The spray format makes it easy to cover mid-lengths and ends, where color damage and dryness are most noticeable.

• Apply 6–10 sprays to damp, towel-dried hair
• Comb through from root to tip to ensure even coverage
• Finish by air-drying or blow-drying; do not rinse out the product
