This paper reviews developments in industrial colorants as active ingredients of commercial products that rely on oxidative chemistry for the coloration of human hair. After outlining the regulatory challenges faced by the industry, which are shaping the landscape of colorant usage, the most commercially important actives utilised in oxidative hair colorant formulations are surveyed from the perspective of their chemistry and economics. Some developments in the form of recently introduced actives are also described.
