KÉRASTASE Hydrating Illuminating Shampoo for Blonde Hair — 8.5 oz, Hyaluronic Acid & Shine

KÉRASTASE Blond Absolu Hydrating Illuminating Shampoo is a daily hyaluronic-acid formula designed to gently cleanse, hydrate, and add luminosity to blonde, bleached, or grey hair.

Engineered as part of the Blond Absolu collection, this 8.5 oz shampoo balances moisture and tone for lightened hair without weighing it down. The lightweight gel-lather removes impurities and buildup while delivering hydration to fragile, processed strands. Key actives—including hyaluronic acid for moisture retention and Edelweiss flower extract for antioxidant support—work together to reinforce fiber strength and enhance surface shine for a visibly healthier finish.

How does this shampoo protect and hydrate processed blonde hair?

The formula targets the porosity and dryness common after lightening. Hyaluronic acid attracts and holds moisture within the hair fiber, while nourishing agents smooth and help seal the cuticle to reduce frizz and roughness.

• Hyaluronic acid for sustained hydration and improved strand elasticity.
• Edelweiss flower extract provides antioxidant support against environmental stressors.
• Lightweight cleansing removes residue without stripping natural oils.
• Helps smooth cuticles for enhanced shine and manageability.

Will this shampoo help maintain cool or neutral blonde tones?

Blond Absolu Hydrating Illuminating Shampoo is formulated to preserve luminosity and support tone when used within a blonde-care routine. It pairs well with anti-brass purple treatments in the Blond Absolu range to control warmth and refresh color.

• Use alternately with a purple or ultra-violet shampoo to neutralize yellow tones.
• Enhances reflective shine that makes color appear brighter.
• Supports salon color by removing impurities that dull tone.

How should I use it for best results?

Apply to wet hair, emulsify into a gentle lather, and leave on for 2–5 minutes to allow actives to penetrate the fiber. Rinse thoroughly and follow with a conditioner or Cicaflash from the same range for targeted fiber repair and detangling.

• Recommended cadence: daily for hydration, or alternate with Violet/Ultra-Violet shampoo weekly.
• Leave-on time: 2–5 minutes for improved effect before rinsing.
• Pair with Blond Absolu conditioners and masks to restore and seal hair fibers.

What improvements can I expect after regular use?

Regular use aims to reduce dryness, improve smoothness, and restore surface shine on lightened hair. Over time, hair will appear more luminous and feel softer, with reduced visual damage from mechanical styling and environmental exposure.

• Cleaner, less dull-looking blonde with enhanced radiance.
• Improved manageability and reduced frizz due to smoother cuticles.
• Stronger-feeling strands thanks to moisture retention and fiber support.

Who is this for: KÉRASTASE Blond Absolu Hydrating Illuminating Shampoo is intended for anyone with blonde, highlighted, bleached, or naturally grey hair seeking hydration plus visible shine. It suits people who want a daily cleanser that supports salon-treated hair, helps maintain tone when used alongside violet products, and prioritizes moisture and fiber reinforcement without heaviness.
