No link between regular hair coloring and increased risk of cancer with exceptio

A new study conducted by researchers at the Medical University of Vienna has determined that consumers who dye their hair regularly have a higher risk of cancer, with some exceptions.

In the largest survey of its kind, in which more than 117,000 white women over the age of 36 from the United States were surveyed, the research team found that regular hair coloring is detrimental to most cancers.

However, it did find a positive correlation with the risk of basal cell carcinoma, hormone receptor-negative breast cancer and ovarian cancer.

Lead researcher Eva Schernhammer, of the research team, said: "The current prospective cohort study provides some reassurance against concerns that personal use of permanent hair dyes may increase the risk of cancer or death."

"Nonetheless, we also found a positive association in the risk of certain cancers."

In a study published last year with nearly 47,000 participants, scientists at the National Institutes of Health also found that women who used permanent hair dyes and chemical hair straighteners had a higher risk of developing breast cancer.

Researchers said those who used permanent hair dyes regularly were 9 percent more likely to develop breast cancer than those who didn't use them.
