Experience the rejuvenating effects of Kérastase Première Sérum Filler Fondamental, a weightless leave-in treatment crafted to repair and enhance the inner vitality of all hair types, leaving it lustrous and flexible.
Due to its heightened porosity, processed hair absorbs three times more calcium from water than untreated hair, leading to a detrimental calcium overload visible both inside and outside the hair fiber. Kérastase Sérum Filler Fondamental offers a dual-action solution: its lightweight, balm-like texture seals the cuticles to protect the hair's surface while replenishing the fiber and fortifying hair strength. Your hair is shielded from the damaging effects of calcium found in hard water, as well as from humidity and heat up to 230°C. Say goodbye to frizz as your hair is left smooth, supple, and effortlessly manageable.
