Arizona accuses L’Oreal of concealing cancer risks linked to hair relaxers

Arizona sued L’Oreal SA, alleging the company concealed cancer risks in its hair relaxer products, which are used mostly by African American women. The state seeks penalties, damages, and a sales halt without warnings. L’Oreal faces over 12,000 similar lawsuits, consolidated in federal court, following a 2022 NIH study linking the products to higher uterine cancer risk. L’Oreal denies the claims, citing rigorous safety reviews.
