Like most of you didn't know this already, but it's more research to pass on to the doubters:


Dark hair dye and chemical relaxers linked to breast cancer

African-American and white women who regularly chemically straightened their hair or dyed it dark brown or black had an elevated risk of breast cancer, recent research suggests.

“I would be concerned about darker hair dye and hair straighteners,” epidemiologist Tamarra James-Todd said after reviewing the report in Carcinogenesis. “We should really think about using things in moderation and really try to think about being more natural.

“Just because something is on the market does not necessarily mean it’s safe for us,” she said in a phone interview. James-Todd, a professor at the Harvard T.H. Chan School of Public Health in Boston, was not involved with the new research.

The study of 4,285 African-American and white women was the first to find a significant increase in breast cancer risk among black women who used dark shades of hair dye and white women who used chemical relaxers.

Black women who reported using dark hair dye had a 51 percent increased risk of breast cancer compared to black women who did not, while white women who reported using chemical relaxers had a 74 percent increased risk of breast cancer, the study found.

The risk of breast cancer was even higher for white women who regularly dyed their hair dark shades and also used chemical relaxers, and it more than doubled for white dual users compared to white women who used neither dark dye nor chemical straighteners.
