A new investigation by Consumer Reports has found cancer-linked chemicals in all tested samples of synthetic braiding hair, raising concerns about the safety of these widely used products.
The consumer advocacy group tested 10 popular synthetic braiding hair brands and discovered that every sample contained carcinogens — substances that may cause cancer. The study, which began in 2024, aimed to assess the presence and potential health risks of harmful chemicals in these hair products.
“We have a long history of testing for heavy metals,” said James Rogers, director of product safety testing at Consumer Reports. “We checked for arsenic, cadmium, lead, and also volatile organic compounds, which are man-made chemicals released when products are heated.”
The results were troubling. Nine out of the ten products contained lead and other volatile organic compounds (VOCs), such as acetone. Most notably, all samples contained methylene chloride, a substance linked to cancer.
Rogers explained that even small amounts of lead are harmful. In adults, lead exposure can damage the brain, weaken the immune system, and make it harder to fight infections. For children, the risk is even greater. Lead can interfere with brain development, leading to reduced IQ and behavioral problems.
Although the levels found in the hair were not considered immediately dangerous, Rogers emphasized the need to limit exposure — especially since these chemicals are already present in other parts of daily life.
“We don’t believe these chemicals should be in the products,” Rogers said. “You’re already exposed to them from other sources, so it’s important to reduce any additional exposure when possible.”
Rogers did not call for people to stop using synthetic braiding hair altogether, but advised caution. He recommended shortening the time braids are kept in — for example, wearing them for two to three weeks instead of the usual four to six — and increasing the time between braiding sessions. This, he said, allows the scalp and hair to rest and reduces overall exposure.
Consumer Reports also encouraged anyone who experiences a negative reaction from braiding hair to report it to both a health care provider and the Food and Drug Administration.
The findings come amid growing awareness about the ingredients in personal care products and their potential health risks, particularly in communities where synthetic braiding hair is used regularly.
