K18

K18 was born in San Francisco in 2020 through the initiative of Suveen Sahib and Britta Cox, with a clear identity: to apply molecular biology to hair care, surpassing the limits of traditional cosmetic chemistry. The scientific heart of the brand is the K18Peptide™, a patented bioactive peptide developed through computational models borrowed from the biotech industry, designed to reconnect broken keratin chains from within the hair fiber — not just to coat the surface, as conventional conditioners do. This approach has given rise to the term Biomimetic Hairscience: science that mimics the natural structure of hair to act in a biocompatible way. In December 2023, the brand joined Unilever's prestige portfolio, confirming the international recognition of its research model. K18 caters to all hair types and textures, with particular attention to those facing damage from coloring, bleaching, chemical treatments, or heat.
