Hair Products that Contain Cancer Causing Chemicals
In 2022, the National Institute of Environmental Health Sciences (N.I.E.H.S.) published findings of their Sister Study, including data from over 33,000 women who were tracked for nearly 11 years.
Within that time frame, 378 women were diagnosed with uterine cancer. Those who used hair straighteners over four times in the previous year were more than twice as likely to go on to develop uterine cancer compared to those who did not use the products.
Another study, published by Oxford University, concluded that women who used lye-based relaxers had around a 30 percent increased risk of developing breast cancer.
