Kerastase Fusio-Dose Concentre H.A Ultra-Violet (For Lightened, Highlighted Cool Blonde Hair) 10x12ml

Kérastase Fusio-Dose Concentre H.A Ultra-Violet delivers targeted hydration and color preservation specifically engineered for lightened, highlighted, and cool blonde hair. This concentrated boost works simultaneously to reinforce the hair fiber against breakage and shield the cool-toned pigment from UV-induced fading, addressing the primary structural and aesthetic vulnerabilities of decolorized hair.

The formula utilizes hyaluronic acid to draw and retain moisture, significantly improving tensile strength and elasticity. Combined with ultra-violet filters, the concentrate creates a protective barrier that prevents sun exposure from altering the desired cool tone or causing brassiness. Each dose activates immediately upon mixing, ensuring peak performance of active ingredients. Cool blondes require specialized care to counteract yellowing agents found in sun and water; this concentrate's UV filter component actively defends against these shifting tones, extending the life of coloring services between appointments.

• Optimized for lightened, highlighted, and cool blonde hair textures.
• H.A (hyaluronic acid) content provides deep hydration and fiber strengthening.
• Ultra-violet filters protect color integrity and prevent tonal shift from sunlight.
• Fusio-Dose concentrate compatible with Kérastase shampoos, conditioners, and masks.
• Comes in a 10-dose pack, with each unit containing 12ml of product.

The 10x12ml packaging supports consistent maintenance routines, allowing precise dosing to match variations in hair length and condition. Mix with your preferred Kérastase base product via the dedicated machine to customize the treatment intensity and frequency of application, effectively reducing the visible signs of photodamage and dryness that typically diminish hair brightness after repeated chemical processing.
