Hair extensions contain chemicals linked to cancer, new study finds

"More research is needed, however, for government agencies to determine whether the chemical levels found in these products requires greater regulation, the study authors say. The hazardous chemicals we identified each carry their own risks, says Elissia T. Franklin, lead author of the new paper and a research scientist at the nonprofit research organization Silent Spring Institute. Our findings showed that these products can expose [people] to multiple chemicals over time, and through repeated use, these combined exposures add up."

"At least 12 of the 169 chemicals detected in the new analysis have been associated with cancer, birth defects and reproductive issues and are included in California's Proposition 65 hazardous chemicals list. The study, published today in Environment & Health, tested 43 hair extensions, including those made with synthetic hair, as well as untreated raw human hair and other biobased hair, such as those made from banana-based fibers."

Dozens of hair extensions, including artificial and natural braids, contain synthetic chemicals that pose health and environmental hazards. An analysis of 43 products detected 169 chemicals, with at least 12 linked to cancer, birth defects, and reproductive issues and listed under California's Proposition 65. All but two products contained hazardous chemicals; nearly 10 percent had organotin compounds tied to endocrine disruption, and some products exceeded European Union limits. Repeated use can expose people to multiple chemicals over time, leading to cumulative exposures. Further research and regulatory review are needed to assess whether these levels warrant stricter controls, especially given widespread extension use among Black women.
