Study Finds Possible Link Between Hair Straightening Chemicals and Uterine Cancer
Women who use chemical hair straighteners and relaxers may have a higher risk of uterine cancer, according to a new study from researchers at the US National Institutes of Health (NIH).
The study findings were published on October 17, 2022, in the Journal of the National Cancer Institute.
The researchers used data from more than 33,000 women taking part in the Sister Study, a large, ongoing study looking for risk factors for breast cancer and other health conditions.
At the time the women enrolled in the study, they were asked about their use of different kinds of hair products over the previous year, including hair dyes, straighteners and relaxers, and permanents or body waves.
