KÉRASTASE Chroma Absolu Hair Serum for Color-Treated Hair — 5.1 fl oz, Heat Protection to 450°F & Anti-Frizz

This concentrated serum from the Chroma Absolu collection targets the common effects of coloring: increased porosity, surface roughness, and color fading. Designed to be applied to damp, towel-dried hair, it smooths the fiber, reduces frizz, and offers thermal protection up to 450ºF while delivering conditioning active ingredients like lactic acid, Centella Asiatica, and vitamin E. The pump-spray format lets you control coverage for salon-finish results at home.

How does this serum protect colored hair from heat and fading?

The serum forms a protective coating around each strand, helping reduce moisture loss during heat styling and limiting surface abrasion that accelerates fading. Its formulation reduces porosity so color molecules remain more secure in the hair fiber, which helps shade longevity and shine retention.

• Thermal protection up to 450ºF for blow-drying and hot tools
• Moisturizing actives reduce porosity and surface roughness
• Ingredients help preserve color vibrancy and gloss

What benefits will I notice right after using Chroma Absolu Hair Serum?

Immediately after application and styling, hair feels softer, looks smoother, and shows increased shine with reduced frizz. The lightweight texture avoids weighing down fine strands while providing slip for easier detangling and a sleeker finish.

• Instant softness and improved combability
• Reduced frizz and flyaways for a polished look
• Enhanced shine and smoother hair surface

How should I use this leave-in spray for best results?

Spray evenly on damp, towel-dried hair—about 6–10 pumps depending on length and thickness—then distribute with a comb from roots to ends. Do not rinse; you can air-dry or blow-dry to activate the thermal protection and finish styling.

• Apply 6–10 sprays to damp, towel-dried hair
• Comb through to ensure even coverage, do not rinse out
• Air-dry or blow-dry and style as usual

What key ingredients are included and what do they do?

Chroma Absolu Hair Serum blends performance actives to repair and defend the hair fiber. Lactic acid helps rebalance the hair’s porosity, Centella Asiatica supports fiber resilience, and vitamin E contributes antioxidant support that helps maintain the hair’s surface condition.

• Lactic Acid (AHA): reduces porosity and smooths the fiber
• Centella Asiatica: reinforces weakened strands for strength
• Vitamin E: helps condition the surface and supports shine

Who is this for? KÉRASTASE Chroma Absolu Hair Serum is made for anyone with color-treated or chemically processed hair who wants to protect their investment in color while improving softness, shine, and manageability. It's suitable for all hair types that need anti-frizz control and heat defense without heavy buildup; ideal for salon-colored clients, frequent stylers, and those seeking a daily leave-in that supports color longevity.
