1. What is hair colorant safety & allergens?

Oxidative hair dyes contain some of the most potent contact allergens in consumer products^[1]. Para-phenylenediamine (PPD) and para-toluenediamine (PTD) are the primary sensitisers; EU Regulation 2024/996 now mandates individual labelling of 80 hair-dye allergens with concentration limits^[2]. In any country, the cosmetics regulator enforces ingredient restrictions and patch-testing obligations^[3].
