- Scientists find cancer‑linked chemicals in popular hair extensions
A study by the Silent Spring Institute, published in Environment & Health, tested 43 widely sold hair‑extension products-including those made from human hair-and detected dozens of hazardous substances. The chemicals include flame retardants, organotins, and compounds linked to breast cancer, hormone disruption, reproductive harm, and immune effects. Many samples exceeded European safety limits, and the study highlighted limited ingredient disclosure by manufacturers. The findings raise concerns about long‑term health risks, especially for Black women who use extensions at higher rates for cultural and stylistic reasons. The report calls for greater regulation and transparency in the unregulated beauty‑product sector.
