Hair Dye Linked to Breast Cancer Risk
Researchers at the National Institute of Environmental Health Sciences (NIEHS), an organization that’s part of NIH, conducted a study using data responses from 46,709 women. In the study, researchers found that women who had regularly used permanent hair dyes within the last year were 9 percent more likely to develop breast cancer than women who did not use these products. The researchers did not find any significant increases in risks of developing breast cancer for women who used temporary or semi-permanent dyes. The study revealed that women who have their hair done in salons are at lower risks. This hair dye and breast cancer link primarily affect women who regularly use store-bought permanent hair dye.
