KÉRASTASE Blond Absolu Ultra-Violet Purple Shampoo for Blonde & Gray Hair — Neutralizes Brass, Hydrating Tone-Correcting Formula

KÉRASTASE Blond Absolu Bain Ultra-Violet is a purple shampoo that neutralizes brassy yellow tones in blonde, gray, and highlighted hair while nourishing and restoring softness. KÉRASTASE Blond Absolu Bain Ultra-Violet blends concentrated blue and violet pigments with hydrating actives to visibly correct warm undertones and protect strands from daily environmental stress. Designed for lightened, cool blonde, bleached, ashy, and gray hair, this shampoo tones while delivering a conditioning lift that improves manageability and surface shine without leaving hair brittle.

How does this shampoo remove brassy or yellow tones?

The formula deposits blue and violet pigments onto the hair surface to counteract and neutralize unwanted warm and yellow reflections. Pigment molecules bind where needed to visibly cool tonal balance after one application, and regular use helps maintain cooler shades for longer.

• Concentrated blue and violet pigments correct yellow and orange undertones
• Color-depositing action works during the 2–5 minute processing time
• Safe for processed and lightened hair when used as directed

Will this shampoo damage my bleached or highlighted hair?

Blond Absolu Ultra-Violet is formulated to tone while reinforcing softness and resilience rather than stripping or drying out fragile strands. Hyaluronic Acid and nourishing agents help hydrate and smooth the fiber, reducing the appearance of roughness and improving comb-through slip after rinsing.

• Includes Hyaluronic Acid to help retain moisture and plump the hair fiber
• Designed to strengthen and reduce breakage risk with regular use
• Follow with Cicaflash or another conditioner for added protection

How should I use this product for best results?

Use Blond Absolu Ultra-Violet once per week or as needed to refresh cool tones, alternating with a regular cleansing shampoo like Bain Lumière. Apply to wet hair, distribute evenly, lather gently, leave for 2–5 minutes depending on brassiness, then rinse thoroughly and follow with conditioner.

• Apply on wet hair and work into a uniform lather
• Processing time: 2–5 minutes — longer for stronger toning
• Alternate with Bain Lumière and finish with Cicaflash for best fiber repair

What extra protection does it offer against environmental damage?

Beyond tone correction, the shampoo helps shield hair from oxidation and pollution-related dulling that can accelerate brassiness. Antioxidant and protective ingredients help preserve color luminosity, while hydrating components keep the fiber smooth and reflective.

• Helps protect hair from daily oxidation and environmental pollutants
• Supports shine and surface quality to maintain a vibrant blonde look
• Regular regime use prolongs the interval between professional toning

Who is this for: KÉRASTASE Blond Absolu Bain Ultra-Violet suits anyone with lightened, platinum, ashy, highlighted, or naturally gray hair who wants to neutralize warm undertones without sacrificing softness. It's ideal for salon-goers and at-home users seeking a premium toning shampoo that also hydrates and fortifies treated hair when used as part of the Blond Absolu regimen.
