KÉRASTASE Blond Absolu Hydrating Illuminating Shampoo — 8.5 oz, hyaluronic hydration & luminous shine

KÉRASTASE Blond Absolu Hydrating Illuminating Shampoo is a daily hyaluronic-acid shampoo designed to deeply cleanse, hydrate, strengthen, and add luminous shine to lightened, bleached, or grey hair.

This lightweight cleansing formula targets the common needs of blonde and color-treated hair: dryness, weakened fiber, and dullness. The blend centers on hyaluronic acid to boost moisture retention and Edelweiss flower extract for antioxidant protection. Together they remove impurities and buildup while helping to reinforce fragile strands and enhance reflective shine without flattening the hair.

How does this shampoo help fragile, chemically treated blonde hair?

It focuses on restoring moisture and fortifying hair fibers that have been weakened by lightening services. The hyaluronic acid attracts and holds hydration inside the hair shaft while complementary ingredients smooth cuticles, reducing tangles and breakage risk.

• Hyaluronic acid increases moisture retention for suppleness.
• Formulation helps repair and strengthen compromised strands.
• Gentle cleansing removes residue without stripping color-treated hair.

Will it help keep my blonde tones bright and non-brassy?

This shampoo is part of the Blond Absolu range which supports cool, luminous blondes. While it hydrates and illuminates, alternate use with a targeted violet shampoo to neutralize warm brassiness for stronger tone control.

• Illuminating agents revive surface shine for a brighter look.
• Use weekly with a purple/ultraviolet shampoo to combat brass.
• Maintains salon-fresh appearance between color services.

How should I use it in my haircare routine for best results?

Apply on wet hair, massage to lather, then leave the formula on for 2–5 minutes to allow hyaluronic acid and antioxidants to penetrate before rinsing. For comprehensive blonde care follow with the brand’s Cicaflash conditioner and alternate weekly with Ultra-Violet Purple Shampoo.

• Apply to wet hair, work into a foam, leave 2–5 minutes.
• Rinse thoroughly and follow with Cicaflash conditioner.
• Alternate weekly with Ultra-Violet Purple Shampoo for tone control.

What additional benefits and protections does the formula offer?

Besides hydration, the shampoo provides antioxidant defense and cuticle-sealing action that help protect sensitized hair from environmental stressors. Regular use improves manageability and helps hair look smoother and more reflective.

• Edelweiss flower extract supplies antioxidant protection and softness.
• Seals cuticles to reduce frizz and enhance gloss.
• Daily use adds resilience and helps minimize split ends with consistent care.

Who is this for: This shampoo is built for anyone with lightened, highlighted, bleached, or naturally grey/blonde hair who needs a moisturizing daily cleanser that strengthens fragile fibers and increases shine. It's ideal for people seeking a non-stripping, salon-grade product to maintain blonde clarity and softness between salon visits. Avoid using it as your sole anti-brass solution; pair it with a purple/ultraviolet shampoo as needed to neutralize warm tones.
