The European Chemicals Agency (ECHA) updated its official Cosmetics Restricted Substances Database on September 15, 2026. The update covers several ingredients used in hair-coloring products. For certain affected substances, non-compliant products will face market placement restrictions starting January 1, 2027, with additional deadlines in 2028. Hair-color manufacturers and exporters supplying the EU market may need to review formulations, ingredient concentrations, labeling, and compliance documentation to prepare for the upcoming requirements and avoid disruption.
