Scientists from the University of Chicago, along with colleagues from the National Institutes of Health and the Environment, found that straightening curls increases the risk of developing uterine cancer. Results presented magazine Journal of the National Cancer Institute.
The authors analyzed the health data of 34,000 women over 10 years, during which 378 participants were diagnosed with uterine cancer. After analyzing information about women’s lifestyles, scientists discovered that these women had chemical hair straightening.
In other words, those who had at least one procedure during the year were 64% more likely to develop the disease than those who had no chemical correction. The risk was 71% higher for women who frequently chemically straightened their hair four or more times a year.
The procedure is similar to a classic perm – special formulations are applied to the hair, which may contain carcinogens such as parabens, bisphenol A, formaldehyde and dangerous metals.
