K18 Molecular Repair Hair Mask

K18 Biomimetic Hairscience is a disruptive haircare brand founded in 2020 by Suveen Sahib and Britta Cox. The brand gained global fame for its patented K18Peptide, a bioactive peptide that mimics the natural structure of hair to reconnect broken keratin chains at a molecular level, offering a faster and more permanent solution compared to traditional bond builders.

Originally launched as an independent startup based in San Francisco, the brand rapidly expanded through professional salons and retail partnerships worldwide. Its manufacturing is primarily concentrated in the United States to maintain strict quality control over its proprietary biotechnology.

In early 2024, the global consumer goods giant Unilever acquired K18, integrating it into its Prestige beauty portfolio. This acquisition was aimed at strengthening Unilever's presence in the high-growth premium haircare market, providing K18 with the extensive global distribution network and R&D resources of a multinational corporation while maintaining its identity as a science-led innovator.
