long article 5 min

Un reportage de "Cash Investigation", diffusé le 30 mars 2026, enquête sur les colorations capillaires de L'Oréal et les risques potentiels pour la santé. L'enquête révèle que certains produits contiennent des substances chimiques allergènes comme la paraphénylènediamine (PPD) et la paratoluènediamine (PTD), pouvant provoquer des réactions allergiques graves et permanentes. Le reportage met en lumière des études scientifiques documentant ces problèmes d'allergies depuis le début du 20e siècle. Il souligne l'ironie que le fondateur de L'Oréal, Eugène Schueller, avait initialement banni certaines de ces substances avant de changer d'avis, malgré ses propres avertissements sur leurs dangers. Les colorations capillaires représentent un marché de 3,5 milliards d'euros par an pour L'Oréal.
