Who this is for — colorists and salon professionals working with lightened, highlighted cool blonde hair who want to combat brass while restoring vitality to hair that has been bleached or lightened. It’s ideal for clients seeking a longer-lasting cool blondes’ hue without sacrificing softness or strength, and for those who value high-performance, cruelty-free care.

How it works in practice — as part of the Fusio-Dose system, the Concentre H.A Ultra-Violet is paired with a dedicated Booster to tailor treatment to each client. The purple pigment neutralizes brass on contact, while the Hyaluronic Acid and Edelweiss oil rebuild and nourish the hair fiber, addressing both color correction and surface damage in a single, efficient salon service.

In short, this is a professional-grade concentrate—not a generic purple shampoo—that delivers precise color correction and targeted fiber nourishment for cool-blonde clients seeking a luminous, cooler-toned result that lasts.
