Kerastase Fusio-Dose Concentre H.A Ultra-Violet is a concentrated anti-brass purple care designed for lightened, highlighted cool blonde hair. This professional-grade formula is intended to be used exclusively with a Fusio Dose Booster to unlock its full brightening and nourishing potential. Ultra-violet pigments instantly neutralize brassy and yellow undertones, delivering a cooler, more luminous blonde. Two weight molecules of Hyaluronic Acid ensure deeper penetration and a more controlled action on the fiber, while Edelweiss oil delivers antioxidant-rich nourishment to protect and rejuvenate sensitized hair after bleaching or lightening. It replenishes surface damage, leaving hair softer, stronger, and with a colder, shinier appearance. Cruelty-free with no animal testing and designed for professional use only.
