Scientists have found a connection between the frequent use of dyes and hair straighteners and an increased risk of developing breast cancer, Journal of Cancer reported referring to a study.
According to the results of the study, the risk of developing breast cancer was 45% higher for African American women and 7% for white women who dye their hair. And the use of hair straighteners was linked to an 18% increased risk of cancer.
The study does not prove that straighteners and hair dyes are the cause of cancer, it only shows a correlation. However, the authors write that paints and straighteners can play a role in the development of the disease.
Alexandra White from the US National Institute for Environmental Health Research, co-author of the study, notes that you should not worry too much about the results of this study.
The US Food and Drug Administration (FDA) indicates that it does not have reliable evidence of a link between modern hair dyes and cancer. The International Agency for Research on Cancer gives a similar assessment: dyes are not considered carcinogens.
