📢 Introducing Our Latest Hair Care Innovation Today, Kao announced a world-first* discovery by Kao Corporation's Hair Beauty Research, revealing the connection between structural changes in proteins within the hair and the mechanism behind perceptible damage—such as dryness and frizziness—that emerges around seven days after coloring. Further, because such a phenomenon is especially noticeable in black hair, Kao discovered the possibility that the mechanism may involve melanin, and has developed a new technology that reduces hair damage post-coloring and helps maintain luminous, full-bodied color.

Kao searched academic papers on PubMed, the world’s leading scientific literature database for life sciences and biomedicine field, and Scopus, one of the world’s largest scientific abstract and citation databases. No publications describing “Generation of SH groups for seven days after hair coloring” were found as of May 29, 2026.
