KÉRASTASE Blond Absolu Ultra-Violet Purple Hair Mask 6.8 fl oz — Neutralizes Brass, Hydrates with Hyaluronic Acid

KÉRASTASE Blond Absolu Ultra-Violet Purple Hair Mask is a violet-toned treatment that neutralizes brassy yellow and warm undertones while deeply nourishing lightened, highlighted, and gray hair.

This concentrated purple hair mask combines color-depositing pigments with hydrating actives to refresh cool blonde shades and repair processed strands. Designed for hair that’s been lightened, bleached, highlighted, or naturally gray, the formula balances tone and improves manageability without stripping moisture. Use it as a weekly or as-needed corrective treatment to maintain a luminous, cool blonde between salon visits.

How quickly does this mask neutralize brassiness?

The mask starts counteracting warm, yellow tones from the first application thanks to blue and violet pigments that deposit color into the hair fiber. Timing determines intensity: a short application softens mild brassiness while longer exposure produces stronger toning. Results are visible immediately after rinsing and build with repeated use for lasting cooler tones.

• Leave on 3–5 minutes for gentle correction
• Extend application for deeper neutralization as needed
• Use weekly or spot-treat between color refreshes

Will this mask repair damage and improve hair texture?

Beyond toning, the formula includes hyaluronic acid to help plump and hydrate fibers, improving softness and shine. It nourishes processed hair to reduce brittleness and enhance slip for easier detangling. While not a permanent reconstructive treatment, regular use visibly improves feel and resilience.

• Hyaluronic acid adds moisture and surface smoothness
• Conditions lengths and ends to reduce breakage
• Leaves hair looking shinier and easier to style

How should I use the Ultra-Violet mask for best results?

Apply to clean, towel-dried hair, focusing on mid-lengths and ends where brass is most visible. Massage through the strands and allow the mask to work for 3–5 minutes; adapt time to desired toning strength. Rinse thoroughly and follow with styling as usual — protective products can help maintain color balance longer.

• Use on shampooed, towel-dried hair for even pigment deposit
• Target problem areas (roots typically need less pigment)
• Rinse well to avoid over-toning or buildup

Can I combine this with other Blond Absolu products?

Yes — the Ultra-Violet mask pairs well with other Blond Absolu shampoo, conditioner, and concentrated serums to create a full regime for cooling tone and restoring fiber health. A combined routine enhances protection against oxidation and environmental stressors, extending salon results at home. Alternate or layer products based on your hair’s porosity and level of processing.

• Follow with a matching conditioner or serum for added hydration
• Use toning mask weekly alongside color-safe shampoo
• Adjust frequency depending on lightening level and porosity

Who is this for? KÉRASTASE Blond Absolu Ultra-Violet Purple Hair Mask is formulated for anyone with lightened, bleached, highlighted, ashy, or gray hair seeking to neutralize warm undertones while restoring moisture and shine. It’s ideal for salon-colored blondes wanting a professional-level toning boost at home, plus those with weakened or porous strands that need added softness and protective hydration.
