Could hair dyes, relaxers raise breast cancer risk? – Chicago Tribune – Chicago Tribune

The safety of hair products has been debated for years. Now, new research suggests that black women who use dark hair dyes face a higher risk of breast cancer, while chemical relaxers and straighteners boost the odds in white women.

The findings stem from a study of more than 4,000 women. Use of dark brown or black hair dyes by black women was tied to a 51 percent greater risk of breast cancer. And whites who used hair relaxers had 74 percent higher odds.

But while the study found a possible link between the hair products and breast cancer risk, it did not prove a connection.

“Our findings do not suggest that simply using hair dyes, relaxers or both will cause a woman to get breast cancer,” cautioned study lead author Adana Llanos.
