A new link between hair dye and breast cancer? Maybe, says Rutgers study

In the hunt for the causes of breast cancer, Rutgers researchers say they may have found two new possible culprits: Hair dyes and relaxers.

More specifically, darker shades of hair dye.

The possible association between commonly used hair products and the most frequently diagnosed cancer for women came to light in a close look at 4,285 women in New Jersey and New York who have been diagnosed with some form of breast cancer.

The study revealed a different effect based on race.

The women were asked about their use of hair dyes and relaxers – what shade they used, how often they used it, and for how long. It is the first study to take a look at the impact of relaxer products on Caucasian women, said study lead author Adana Llanos, an epidemiologist with Rutgers Cancer Institute of New Jersey and Rutgers School of Public Health.

The study found:

  • For African-American women, a 51 percent increased risk of developing breast cancer among those women who used dark brown or black hair dye (It found no comparable jump for Caucasian women)
  • Also for African-American women, a 72 percent increase in the type of breast cancer known as estrogen-positive among those who used dark brown or black  dye.
  • For Caucasian women, a 74 percent increased risk for those who used chemical relaxers or straighteners.

In addition, the association between hair dyes and cancer was higher – or riskier, in other words – for salon dyes compared to home kits.

The study appears in the June 2017 online issue of Carcinogenesis.

Llanos was quick to caution her study doesn’t “prove” these hair products cause cancer. It’s simply too soon to tell, and more research would have to take a closer look to reach such a conclusion, she said.

Just because we found these associations doesn’t mean that if you dye your hair dark, or any color, you’re going to get breast…

What Does It Mean To Be “Black Butterfly Beautiful”

The image of the butterfly has come to define the many expressions of the feminine black consciousness and for a good reason. The butterfly is the perfect articulation of the exquisite beauty of nature. Whether tiny or large, brightly colored or more subdued, the butterfly’s allure is undeniable. Each one displays its own unique patterns and hues, and no one species outshines any other.

Similarly, there is no one ideal image of a black woman -- each is gorgeous in her right. All African-Americans share a glorious history of struggle and perseverance that has funneled into the modern black renaissance. And, like the graceful butterfly, the awakened black woman exemplifies the dazzling beauty of that cultural evolution.
