Study Finds Breast Cancer Associated With Permanent Hair Dye

The research team found little or no increase in breast cancer risk for semi-permanent or temporary dye use.

The researchers found that women who use permanent hair dye and chemical straighteners have a higher risk of developing breast cancer than women who do not use these products. The study, published in the International Journal of Cancer, suggests that the risk of breast cancer increased with more frequent use of these hair chemicals.

“Researchers have been studying the possible link between hair dye and cancer for a long time, but the results are inconsistent,” said study author Alexandra White of the US National Institute of Environmental Health Sciences (NIEHS).

Among African American women, the use of permanent dyes every five to eight weeks or more was associated with a 60 percent increased risk of breast cancer, compared with an eight percent increase in the risk of white women. The research team found little or no increase in breast cancer risk for semi-permanent or temporary dye use.

An intriguing finding was the association between the use of chemical hair straighteners and breast cancer. The researchers found that women who used hair straighteners at least every five to eight weeks were about 30 percent more likely to develop breast cancer.

Although the association between straightener use and breast cancer is similar in African American and white women, straightener use was much more common among African American women, according to the study. The researchers warned that while there is some previous evidence to support the association with chemical straighteners, these results need to be replicated in other studies.

When asked if women should stop dyeing or straightening their hair, study co-author Dale Sandler: “We are exposed to many things that can potentially contribute to breast cancer, and any factor is unlikely to explain the risk of breast cancer.” woman.

“While it is too early to make a firm recommendation, avoiding these chemicals may be one more thing women can do to reduce their risk of breast cancer,” Sandler said.
