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

KÉRASTASE Chroma Absolu Hair Serum is a leave-in smoothing spray that shields color-treated hair from heat, humidity, and frizz while restoring softness and shine.

This lightweight serum is designed specifically for dyed and chemically processed hair, combining protective technology and nourishing actives to preserve color vibrancy and improve manageability. Use it on damp, towel-dried hair before styling to lock in moisture, reduce porosity, and create a smoother finish that lasts through styling and environmental exposure.

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

The formula forms a protective barrier that reduces damage from heat tools and external aggressors, helping color last longer and appear glossier. It lowers hair porosity so color molecules remain more stable and cuticles lie flatter for enhanced light reflection.

• Heat protection up to 450°F for safer blow-drying and hot tools
• Creates a seal to limit color washout and fading
• Improves cuticle alignment to boost shine and smoothness

What nourishing ingredients are included and what do they do?

The serum blends targeted actives to rebuild weakened fiber and replenish moisture without weighing hair down. These components work together to strengthen strands, minimize frizz, and support a healthier-looking finish after color services.

• Lactic Acid (AHA): helps refine fiber texture and reduce surface irregularities
• Centella Asiatica: supports resilience and visibly improved hair quality
• Vitamin E: an antioxidant that helps protect hair from environmental stressors

How do I use it for best results on busy mornings?

Spritz the serum onto damp, towel-dried hair and comb through to distribute evenly—no rinse required. You can air-dry for a naturally sleek look or blow-dry for smoother results; both methods lock in benefits and reduce styling time.

• Apply 6–10 sprays for medium-length hair, adjusting for thickness and length
• Comb from roots to ends to ensure full coverage before drying
• Suitable as a primer before heat styling to limit frizz and boost shine

Will this make my processed hair feel heavy or greasy?

The serum is formulated to be lightweight so it adds softness and shine without a weighed-down finish. It targets weakened fibers and surface frizz while maintaining natural movement and body.

• Non-rinsing, fast-absorbing texture that leaves hair touchable
• Designed to preserve salon-finished volume and manageability
• Works on all types of color-treated hair, from highlights to full color

Who is this for: KÉRASTASE Chroma Absolu Hair Serum is intended for anyone with color-treated, highlighted, or chemically processed hair who wants to protect color, reduce frizz, and enhance softness and shine. It’s especially useful for people who heat-style regularly or whose hair is showing signs of porosity and surface damage after coloring.

How to apply: On damp, towel-dried hair, spray evenly (6–10 pumps). Comb through and style as desired — air-dry or blow-dry. Do not rinse.

Key benefits: heat defense up to 450ºF, frizz reduction, color protection, restored softness, added shine, and fiber reinforcement with lactic acid, Centella Asiatica, and Vitamin E.

Packaging: 5.1 fl oz (150 ml) easy-spray bottle for controlled application and travel-friendly use.
