You can't wear after-shave or perfume or hair gel or scented deodorant or even use a shampoo with any discernible smell. Don't even think about showering with a scented soap or shower gel.

MCS victims are highly susceptible to common chemicals.
Extremely low levels of exposure, which don't bother normal folks, make life miserable for MCS sufferers. Things we take for granted, like the ink on magazines or the smell of a new car or the touch of synthetic fibers or just about everything else that makes the modern world modern, gives them severe reactions. Some of them hang their mail outside for weeks before daring to open it. Some insist on clothes that are not only made from all natural fibers, but unbleached and uncolored. Many live as far away from civilization as possible, in houses carefully constructed to use a minimum of chemicals.
