Although concentrations in the United States are quite low, there is concern that some chemicals in the mixture may increase cancer risk. If one cell acquires enough mutations to become cancerous, it gives rise to subsequent cancer cells. Although the public generally associates carcinogenicity with synthetic chemicals, it is equally likely to arise in both natural and synthetic substances. However, it has classified some chemicals that are or were used in hair dyes as “reasonably anticipated to be human carcinogens.” (For more information on the classification systems used by these agencies, see Known and Probable Human Carcinogens.)
