According to a study by Professor Kefah Mokbel, a breast cancer surgeon at the Princess Grace Hospital in London, women who colour their hair have a 14 per cent higher chance of getting breast cancer.

Professor Mokbel advises women to use as many natural products on their hair as possible, suggesting rose hip, henna or beetroot, and recommended them to dye their hair no more than two to five times per year, according to the Sunday Times.
“Although further work is required to confirm our results, our findings suggest that exposure to hair dyes may contribute to breast cancer risk,” his study concluded. “What I find concerning is the fact that the industry recommends women should dye their hair every four to six weeks.”

Professor Mokbal made also clear on Facebook that the relation is a correlation and the positive association between the use of hair dyes and risk of breast cancer does not represent evidence of a cause-effect relationship.

Another study published earlier this year found also that hair dyes increased the risk of breast cancer. Sanna Heikkinen from the Finnish Cancer Registry said to Kievikeli Magazine, that Finish researches found a link between hair dye and breast cancer.

“We did observe a statistical association between hair dye use and risk of breast cancer in our study but it is not possible to confirm a true causal connection,” she explained. “It might be, for example, that women who use hair dyes also use other cosmetics more than women who reported never using hair dyes.”

However according to the National Cancer Institute studies of breast and bladder cancer have produced conflicting results. While some studies have shown a link between hair dye usage and increased risk of some cancers, other studies have not shown these links.

This includes younger generations who use hair dye, so it is important that more studies are done to get a better idea if dyes can create a greater threat of getting cancer.
