Hair Relaxer Law Suits

On October 17, 2022, a National Institute of Environmental Health Sciences (NIEHS) study revealed that women who used chemical hair straighteners suffered a higher rate of uterine cancer compared to individuals who did not use these products. The study involved 33,497 U.S. women ages 35-74. The women were followed on average for nearly 11 years. During this period, 378 uterine cancer cases were diagnosed. Women who used hair straightening products more than four times in the year prior to enrollment were twice as likely to develop uterine cancer compared with the women who did not use the products. Studies have shown that up to 90% of Black and Brown women have used hair relaxants or straighteners.
