Department of modern perils

So I stopped by my hair salon to make an appointment to get my hair cut, and I noticed (how could I not?) that my stylist was wearing a gas mask to give a client a Brazilian straightening. And it got me to thinking. Shouldn't the client have been wearing a gas mask too? And maybe she needs to wear it for months, until the formaldehyde washes out entirely? And maybe any customer who walks in should be offered a gas mask as well? Maybe I'll just forget the haircut. Too dangerous.
