NIH study finds Black women may be more affected due to higher use.
A version of this article was first published on National Institute of Health, News
Researchers found that women who used chemical hair straightening products had a higher risk of uterine cancer than women who did not.
The study included 33,497 U.S. women ages 35-74 participating in the Sister Study. The researchers found that women who used hair straightening products more than 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.
Studies show that uterine cancer incidence rates have been rising in the United States, particularly among Black women. Black women use hair straightening or relaxer products more frequently and tend to initiate use at younger ages than other races and ethnicities.
Researchers found that women who used straighteners had an increased risk of hormone-related cancers. They did not collect information on brands or ingredients in the hair products the women used.
The National Institute of Environmental Health Sciences (NIEHS) published a study that found a relationship between straightener use and uterine cancer. The study found that permanent hair dye and straighteners may increase breast and ovarian cancer risk.
