Study Finds Link Between Hair Straighteners and Uterine Cancer
The study , which was published in the Journal of the National Cancer Institute on October 17, 2022, looked at the association between the use of chemical hair straighteners and a potential increased risk of uterine cancer. The researchers followed 33,497 women over an 11-year period and found at least 378 participants who developed uterine cancer during that time.
The study determined that women who reported frequently using chemical hair straighteners (at least 4 times over the previous year) were more than 2.5 times more likely to develop uterine cancer compared to women who never used the products.
Over 60% of the women who participated in the study identified as African American. It is important to note that the research did not find the relationship between hair straightener use and the incidence of uterine cancer differed by race. However, "because Black women use hair straightening or relaxer products more frequently and tend to initiate use at earlier ages than other races and ethnicities, these findings may be even more relevant for them," said Che-Jung Chang, Ph.D., a co-author of this study.

Lawsuit Blames Woman's Uterine Cancer on Hair Relaxers
In a federal lawsuit  filed just days after the above study was published, a Missouri woman blames the hair relaxer products she had been using since third grade for her development of uterine cancer.
Plaintiff Jennifer Mitchell said societal pressure pushed her to start using hair straighteners at such a young age - that she felt a need for her hair to "look a certain way, lay a certain way, flow a certain way in order to look professional" and "fit in." In 2018, the 28-year-old was diagnosed with uterine cancer and underwent a hysterectomy, ending her chances of becoming a mother.
"I felt deceived. I felt hurt. I felt like I've been lied to my whole life," Mitchell said, adding, "In some sense, you had to conform to look a certain way for societal norms."
Mitchell is suing L'Oréal, SoftSheen Carson, Strength of Nature, Dabur, and Namaste Laboratories. The lawsuit alleges that the companies knew, or should have known, that their hair care products increased the risk of cancer but manufactured and distributed them anyway while failing to warn consumers of the potential health risks.

Permanent Hair Dyes, Relaxers Linked to Breast Cancer Risk
A December 2019 study published online by the International Journal of Cancer  suggested that permanent hair dye and chemical hair straighteners could increase breast cancer risk, especially for black women. After 8 years of follow-up, the researchers found that:
- Women who regularly used permanent hair dye in the 12 months before joining the study were 9% more likely to develop breast cancer than women who didn’t use hair dye.
- Black women who used permanent hair dye every 5 to 8 weeks or more in the 12 months before joining the study were 60% more likely to develop breast cancer than women who didn’t use hair dye.
- White women who used permanent hair dye every 5 to 8 weeks or more in the 12 months before joining the study were 8% more likely to develop breast cancer than women who didn’t use hair dye.
- The association between using chemical hair straighteners and higher breast cancer risk was similar among Black women and white women, but Black women were much more likely to use hair straighteners than white women.
