Women should dye their hair no more than six times a year and use natural ingredients to reduce the risk of cancer, a breast surgeon has claimed.
Professor Kefah Mokbel, of the Princess Grace Hospital in central London, found that women who colour their hair are 14 per cent more likely to suffer breast cancer.
Kefah Mokbel, a breast cancer surgeon at the Princess Grace Hospital in London, reviewed studies on whether there is any link between hair dyes and breast cancer and it was found that there is 14 percent increase in the disease among women who dye their hair frequently, Sunday Times of London reported.
“Although further work is required to confirm our results, our findings suggest that exposure to hair dyes may contribute to breast cancer risk,” researchers mentioned.
Kefah Mokbel suggested using products with natural ingredients such as beetroot and while limiting the dyeing to only up to five times in a year.
In fact, not only hair dyes, chemical relaxers used by women can increase the risk of developing the disease. In a separate study, researchers at Rutgers University found that both cause an alarming increase in the risk of developing breast cancer.
According to Daily Mail, the study was conducted by researchers at the Rutgers School of Public Health and Rutgers Cancer Institute of New Jersey. After examining the participants it was found that black women who used dark hair dye had an overall 51 percent greater risk of cancer and a 72 percent increased risk of developing estrogen receptor-positive breast cancer.
In a separate study, Finnish researchers found that women using hair dye were more likely to develop breast cancer but it’s not clear if the products were the direct cause of it.
Sanna Heikkinen of the Finnish Cancer Registry told NewYork Post: “It might be, for example, that women who use hair dyes also use other cosmetics more than women who reported never using hair dyes.”
