I am glad that they have statistical evidence, however it has been believed for a long time. Beauty salons use a wide variety of products that are biologically active and unregulated. Many are known carcinogens, and working at a beauty salon puts you at increased risk of cancer. See https://www.ncbi.nlm.nih.gov/pubmed/19755396 https://www.ncbi.nlm.nih.gov/pubmed/19755396 for random verification. The question is what it does to the customers. It has long been suspected that increased cancer rates among blacks are tied to the fact that they are more likely to use beauty salons than whites. And if they do use them, they use them more often.
