Research published in the Journal of the National Cancer Institute (NCI) tracked thousands of American women for more than a decade and found an association between the use of hair-straightening chemicals and an increased risk of developing uterine cancer. While uterine cancer has been rare, cases have been steadily rising across the country in recent years. In the recent NCI study, women who used hair straightener products were more than twice as likely to develop uterine cancer than those who did not use them at all.
