Today many sources are reporting that frequent hair dying is being linked to an increase in breast cancer. However scientists are stressing that there is no definite relationship.

A study has been published by London surgeon Kefah Mokbel that women who dye their hair on a regular basis have a 14 percent increase of developing breast cancer. 

Mokbel advises women to dye their hair no more than 5 times a year because of this. He also has recommended using as many natural products as an alternative to chemical and synthetic dyes. 

“What I find concerning is the fact that the industry recommends women should dye their hair every four to six weeks,” Professor Mokbel stated.

“Although further work is required to confirm our results, our findings suggest that exposure to hair dyes may contribute to breast cancer risk.”

However Mokbel has had to defend his findings. Sanna Heikkinen said that “We did observe a statistical association between hair dye use and risk of breast cancer in our study,” but she stressed that scientists aren't certain of any relationship between the two findings. 

Heikkinen of the Finnish Cancer Registry added “It is not possible to confirm a true causal connection,” she said. “It might be, for example, that women who use hair dyes also use other cosmetics more than women who reported never using hair dyes.

Haircare professional at the CTPA (Cosmetic Toiletry and Perfumery Association) have stated that all hair dyes are rigorously tested and undergo go robust safety requirements.
