Dyeing and straightening can cause breast cancer

Hair straightening increases the risk of breast cancer by 30% for all skin types, hair dyeing increases the risk for black women by 60%.

For decades, scientists have been debating whether hair dye can cause cancer. The analysis often produces different or inconsistent results.

However, research published on December 4 by a US government agency showed that black women using hair dye products have a 60% higher risk of breast cancer. Meanwhile, white women dyed their hair do not bear this risk.

The study was conducted by the National Institute of Environmental Health Sciences, part of the U.S. Department of Health and Human Services, from 2003 to 2009, based on health data for more than 46,700 women, ages 35 to 35. 74. To control the genetic predisposition, all participants had at least one sister or sister in the family with breast cancer.

The scientists said that the cause is in different ingredients in dyes used for white and black people; or the amount of medication; or separate hair structures of the two races; The permeability of different skin types.

Research is also done on hair straightening products. The results showed that all women who had their hair straightened had a 30% higher risk of breast cancer, regardless of skin color.

However, some scientists say it is not possible to confirm breast cancer hair styling products for women. Moreover, it is difficult to identify the general risks associated with hair dyeing for African-American women. The number of black women in the study is less than 10%.

Data in the study was not large enough, said Dr. Larry Norton, Medical Director of Evelyn H. Lauder Breast Cancer Treatment Center."You cannot rely on these data, the impact is too small," he commented.
