This line at the end of the article irked me. A friend of mine who was a hair stylist for 20 years is dying of brain cancer and her doctor's are pretty sure her exposure to chemicals on a daily basis had a role in her cancer.
While I understand the comment's attempt at humor, the risk these people have with their exposure to harmful chemicals is very real.
Could society adapt for those workers to start wearing masks or similar protection. Doctors do that all the time, why not hairdressers?
Of course they do, because they are also humans vulnerable to diseases. Even more so because they are exposed daily and are usually not the ones introducing diseases into the environment. The masks protect both the patient and the doctor. Mask can also protect doctors from chemicals they might be routinely exposed to.
In any case, they wear masks. Your comment is a red herring. The important part is the social stigma of (not) wearing masks and how to prevent it.
