Researchers at the Silent Spring Institute, a scientific research nonprofit organization based in Massachusetts, tested 43 hair extension products purchased online and from local beauty supply stores and identified 169 chemicals present overall, including dozens of harmful substances such as flame retardants, pesticides and compounds used to stabilize plastics.
A dozen of the compounds found are listed under California’s Proposition 65, known as the Safe Drinking Water and Toxic Enforcement Act of 1986, which warns residents of chemicals known to cause birth defects, cancer and reproductive issues. Additionally, 17 compounds that have been linked to breast cancer were found in 36 samples tested, the researchers said.
