Soft & Beautiful toxic hair relaxers
The Soft & Beautiful chemical hair relaxer line is manufactured by the US-based Strength of Nature cosmetics company. Although the company's chemical hair straighteners are marketed as safe hair care products containing natural oils such as olive, argan, and coconut oils, these hair relaxers also have a strong mix of chemicals that can cause severe health conditions. The Sister Study's initial results showing an association between chemical hair relaxers' use and higher uterine cancer rates prompted several toxic hair relaxer lawsuits in the United States. The decade-long major clinical study was conducted by the National Institutes of Health and it was published in 2022.
