CNN —Scientists are uncovering new details in the connection between using certain hair straightening products, such as chemical relaxers and pressing products, and an increased risk of cancer in women. The study, published Monday in the Journal of the National Cancer Institute, estimates that among women who did not use hair-straightening chemical products in the past 12 months, 1.6% developed uterine cancer by age 70, but about 4% of the women who frequently use such hair-straightening products developed uterine cancer by age 70. That finding “also communicates that uterine cancer is indeed rare. “In this study, women with frequent use in the past year had an over two-fold higher risk of uterine cancer,” she said. The researchers found a strong association between hair straightening products and uterine cancer cases but the use of other hair products – such as dyes and perms or body waves – was not associated with uterine cancer.

Women using chemical hair-straightening products are at a higher risk of uterine cancer than women who reported not using them, a new study by the National Institutes of Health (NIH) found. Researchers noted that Black women may have a higher risk because they are more likely to use those products more frequently. “Sixty percent of the participants who reported using straighteners were Black women. The bottom line is that the exposure burden appears to be higher among Black women,” Chandra Jackson, an NIEHS Earl Stadtman Investigator who co-authored the study, said. Advocates like Greene, one of the leading voices in the movement against Black hair discrimination, have highlighted that wearing natural hair isn’t easy or always safe for Black people.
