Kérastase Première Sérum Filler Fondamental represents a feather-light leave-in remedy crafted to internally mend all varieties of damaged hair, leaving it with a radiant sheen and supple texture.
Due to heightened porosity, processed hair absorbs triple the amount of calcium from water compared to untreated strands, resulting in a detrimental calcium overload that manifests both internally and externally within the hair fibre. Kérastase Sérum Filler Fondamental adopts a dual-pronged approach: its airy, balm-like consistency adeptly seals the cuticles, safeguarding the hair’s surface, while simultaneously infusing the fibre with fortifying agents, enhancing hair resilience.
