Diamond and Diamond Lawyers Pursue Class Action Lawsuit Against L'Oréal Over Alleged Cancer Risks from "Dark and Lovely" Hair Relaxers
VANCOUVER, BC , June 24, 2025 /CNW/ - Diamond and Diamond Lawyers has filed a proposed class action against L'Oréal and its subsidiaries, alleging the company failed to warn consumers, primarily women of colour, about serious health risks linked to its "Dark and Lovely" hair relaxer products.
Filed in the Supreme Court of British Columbia , the lawsuit claims these relaxers contain unsafe levels of Endocrine Disrupting Chemicals (EDCs) that are associated with respiratory and cardiovascular problems, diabetes, as well as reproductive cancers, including uterine, endometrial and ovarian cancer. These chemicals can also cause fibroids, damage the nervous and immune systems, as well as lead to neurological and learning disabilities.
" These products were marketed as safe for decades. Our lawsuit alleges that L'Oréal ignored scientific evidence and failed to take appropriate action ," said Darryl Singer , Head of Class Actions at Diamond and Diamond Lawyers.
The Plaintiffs allege that L'Oreal:
Has sold and marketed toxic relaxer products since approximately 1970
Failed to test for or detect the presence of EDCs prior to sale
Ignored consumer complaints and failed to initiate recalls or safety warnings
Mislead the public through deceptive marketing, in violation of the Business Practices and Consumer Protection Act, Competition Act and Sale of Goods Act
Scientific studies published in 2012 and 2021 highlighted significant links between hair relaxer use and reproductive health issues. Despite these findings, L'Oréal has not acknowledged any potential danger associated with the products.
The lawsuit names two representative plaintiffs and seeks to certify a broader class of affected consumers across Canada .
