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

KÉRASTASE Blond Absolu Ultra-Violet is a purple-depositing hair mask that neutralizes brassy and yellow undertones while nourishing lightened, highlighted, and grey hair.

This concentrated purple mask was created to refresh cool blonde, bleached, and ashy or grey tones between salon visits. It combines violet and blue pigments to visually counteract unwanted warmth, plus Hyaluronic Acid to hydrate and fortify the hair fiber. The result is a visibly cooler, shinier finish with reduced brassiness and improved softness when used regularly as part of a blonde maintenance routine.

How quickly will it reduce brassy or yellow tones?

Neutralization begins as soon as pigment is deposited on the hair shaft during application. Most users notice an immediate toning effect after rinsing, with cumulative improvements over repeated use.

• Apply to towel-dried, shampooed hair for even pigment absorption.
• Leave on 3–5 minutes for light neutralization; extend time for stronger toning.
• Rinse thoroughly to avoid any residual tint build-up.

Will this mask damage my bleached or processed hair?

The formula is designed for processed hair and includes moisturizing and strengthening ingredients to help reduce breakage and improve manageability. It deposits color without the oxidizing action of a permanent dye.

• Hyaluronic Acid helps replenish hydration and plump the hair fiber.
• Color-depositing pigments neutralize brass without bleaching or lifting.
• Use as a weekly or biweekly treatment depending on hair porosity and color needs.

How should I use it for best results?

Follow a simple routine to get consistent toning and conditioning. Proper application and timing let you control the degree of neutralization while restoring softness and shine.

• Shampoo and towel-dry hair before applying the mask to lengths and ends.
• Massage evenly, let sit 3–5 minutes or longer for deeper toning, then rinse.
• Adjust frequency based on how quickly your hair shows warmth; combine with Blond Absolu shampoo and conditioner for a complete regimen.

How does this fit into my blonde care routine?

Think of the mask as a corrective and restorative step that complements cleansing and maintenance products. It’s best used alongside the Blond Absolu range to maintain cool tones, protect against environmental stressors, and preserve hair health.

• Alternate with a clarifying or repair shampoo if hair is heavily product-laden.
• Pair with Blond Absolu conditioners or leave-in treatments to seal and protect the fiber.
• Use regularly to extend salon color life and reduce the need for frequent toning appointments.

Who is this for: Ideal for anyone with lightened, highlighted, bleached, ashy, or grey hair seeking to neutralize yellow and brassy undertones while improving moisture, shine, and resistance to breakage. It is suitable for damaged or porous hair that needs both pigment correction and replenishing care. Professional stylists and at-home users can tailor application time to match the desired level of toning.
