Study raises concerns about hair dyes and chemical straighteners

For black women, the risk could be as high as 45% which the study suggests is likely due to different chemicals in hair products specifically for black women's hair texture.

The risk was substantially higher among black women.

"In our study, we see a higher breast cancer risk associated with hair dye use, and the effect is stronger in African American women, particularly those who are frequent users", Alexandra White, corresponding author and head of the National Institute of Environmental Health Sciences (NIEHS), said in a statement.

More than half of the women reported using permanent hair dye, and 75% of black women said they used chemical straighteners.

Another breast cancer expert was a little more dubious about the study's methodology and findings.

Researchers say that more research needs to be done.

A large study led by government scientists is renewing concern about whether chemicals used to dye and straighten hair raise the risk of cancer. Other factors could be to blame for the increase.

The link between straightener use and breast cancer was analogous in African American and white women, but straightener use was much more customary among African American women.

The study done by IJC by used questionnaires sent to 47,650 participants that asked them how often they used temporary, semi-permanent, or permanent hair dye and chemical hair straighteners (i.e. relaxers, Brazilian Keratin treatments, etc.).

Still... some preliminary research has linked hair dye to blood and bladder cancer. Women answered questions about their use of hair dyes and straighteners. Even so, it might be wise to avoid chemical straighteners and permanent hair dyes, she said.

Added all together, translating one study into a word of advice for any one individual is impossible. But it used data from the '90s.

"The study was U.S. based, so it's also not clear if the products would be similar to those used in the United Kingdom". One fact which can not be ignored about this health study is that it's been done on fewer than 10% of black women just for once that too more than eight years on an average.

"Sometimes science just can not give us the answers that we want it to give us", says Brawley. Around nine percent of the participants were African American women.

Definitively identifying causes of breast cancer might be limited by current science, said Dr. Otis Brawley, professor at the Johns Hopkins University Bloomberg School of Public Health and former chief medical officer of the American Cancer Society. When the study is compared with white women, it showed that white women did not have such type of risk.
