KÉRASTASE Purple Hair Mask for Blonde, Grey & Highlighted Hair — Ultra-Violet 6.8 fl oz, Hyaluronic Acid

KÉRASTASE Blond Absolu Ultra-Violet Purple Hair Mask is a rich, color-depositing treatment formulated to neutralize brassy yellow tones and deeply nourish lightened, highlighted, or grey hair.

This intensive purple mask blends concentrated blue and violet pigments with hyaluronic acid to refresh cool blonde and gray shades while restoring moisture and strength to chemically treated hair. It works as a periodic corrective treatment or part of a regular blonde-care routine to maintain cooler tones, help reduce breakage and enhance shine. The texture is creamy and spreadable, designed for even pigment distribution and easy rinsing.

How does the purple pigment neutralize brassiness?

The mask uses complementary color science: blue and violet pigments counteract warm yellow and orange undertones that appear after lightening. Pigments deposit gently onto the hair surface, toning unwanted warmth without permanently altering the base color. Results depend on starting shade and application time; shorter processing tones subtly, longer processing increases neutralization.

• Concentrated blue and violet color-depositing pigments for visible toning
• Adjustable processing time (3–5 minutes standard) for control over intensity
• Even pigment spread from creamy, emollient texture to avoid patchiness

Will this mask repair and hydrate bleached or damaged hair?

Alongside toning pigments, the formula includes hyaluronic acid and nourishing agents that help rehydrate and plump the hair fiber. While it doesn't reconstruct hair like a professional bond-builder, regular use improves softness, reduces frizz, and helps hair look healthier and more luminous. It also adds slip for easier detangling and comb-through after treatment.

• Hyaluronic acid replenishes moisture and helps hair feel fuller
• Conditioning ingredients increase smoothness and manageability
• Reduces surface roughness for enhanced shine and easier styling

How should I use this mask for best results?

Apply the mask to shampooed, towel-dried hair, focusing on mid-lengths and ends where brassiness and damage are most evident. Massage evenly, then leave on for 3–5 minutes for typical toning; extend the time cautiously for stronger neutralization. Rinse thoroughly and follow with your usual routine; use once a week or as needed based on how quickly your color shifts.

• Use on clean, damp hair for even pigment absorption
• Standard leave time: 3–5 minutes; longer for stronger toning
• Rinse well and repeat weekly or when brassiness returns

Can this be used on grey or naturally light hair?

Yes — the mask is suitable for grey, silver, and naturally light hair that develops yellowing over time. Because grey hair can absorb pigment differently, monitor processing time to avoid an overly cool or violet cast. It’s a flexible option for anyone seeking to keep cool tones crisp between salon visits.

• Effective on bleached, highlighted, ashy, and grey hair
• Adjust processing time for delicate or highly porous grey hair
• Works as maintenance between professional toning services

Who is this for: Ideal for anyone with lightened, highlighted, bleached, ashy, or grey hair who wants a salon-grade at-home treatment to neutralize yellow or brassy undertones while improving softness and shine. It suits users looking for a weekly corrective mask that combines color-depositing toning with hydration and protection for processed hair. If you prefer subtle control, follow shorter application times; for stronger toning, increase time cautiously and monitor results.
