Hairstylist sues leading cosmetic brand over cancer risk from hair dyes
His suspicions grew after a conversation with his doctor, who casually linked his illness to his job.
California hairdresser Hector Corvera is suing L’Oréal and several other beauty brands, claiming that years of exposure to harmful chemicals in hair dyes led to his bladder cancer diagnosis.
Corvera, who left behind a childhood in farm labor for a career in hairstyling, never imagined his new profession would pose such a serious health risk.
His suspicions grew after a conversation with his doctor, who casually linked his illness to his job. Months later, a law firm investigating the issue reached out, prompting him to take legal action.
The lawsuit, filed in Los Angeles, argues that major hair product manufacturers, including Wella, Clairol, and John Paul Mitchell Systems, failed to properly test their products, knowingly exposing professionals to carcinogens.
Research has long suggested a heightened cancer risk for hairdressers due to prolonged contact with toxic substances like 4-aminobiphenyl (4-ABP), yet product labels often lack full ingredient transparency.
Corvera hopes his case will push for industry reforms, better regulations, and increased awareness of the risks hair professionals face daily.
