Kerastase Fusio-dose Booster Nutrition 120ml

Target severe dehydration by penetrating directly into the hair shaft with this intensive liquid treatment, leveraging arginine and niacinamide to restore internal moisture where traditional masks fall short.

This targeted hair therapy replaces slow-absorbing surface creams with a fast-delivering formula designed for users needing measurable improvement in moisture retention. Each application releases active nutrients directly along the strand, instantly smoothing the cuticle while reinforcing the internal lipid balance. The resulting hair holds hydration significantly longer between washes, resists humidity-induced frizz, and maintains softness through repeated heat styling cycles.

The treatment integrates flexibly into existing routines based on your preference and available tools. Apply the concentrate by hand to damp or dry hair, allow it to develop for ten to fifteen minutes, then rinse thoroughly. Alternatively, pour the portion into your current shampoo or conditioner bottle and shake gently to create a continuously nourishing base. You may also load it into the official Kérastase Fusion-Dose apparatus for automated, evenly distributed dispensing. Schedule applications once weekly, increasing frequency only if your hair undergoes frequent bleaching, keratin services, or daily thermal tool exposure.

Select this booster when standard deep conditioning fails to reverse long-term dryness or leaves noticeable residue on delicate textures. By prioritizing structural nourishment over temporary slip, the solution restores elasticity and protects color-treated surfaces without drag-down weight at the roots. It addresses the specific nutrient deficit that keeps fine, mature, or environmentally stressed hair from performing reliably under professional styling conditions.
