Physical Danger
Ever wonder what sort of toxic chemicals they put into nail polish or those acrylic nail wraps that make you woozy just walking into a nail salon?
A manicurist has to make sure not to breathe in those chemicals all day.
Even if you use the formaldehyde-free or toluene-free polish, there's still some harsh stuff being used when it comes to nails, so definitely make sure there's proper ventilation, as the nails shouldn't literally be "to die for."
