Physical Danger
Have you ever heard of formaldehyde? Colorless, strong-smelling poisonous gas? Linked to cancer?
Well, it's also in products commonly found in beauty salons. Hair dyes, chemical peels, chemical relaxants, shampoo, brow and lash tints...they're filled with scary-sounding words like "acetone" and "methyl ethyl ketone." But don't worry—they're all okay with very limited exposure. In other words, you're fine if you paint your nails once in a while. If you spend your entire life painting nails? Well, no guarantees there.
Add that to the possibility of burning yourself on a curling iron, and the long-term damage that comes with being on your feet all day, and you might find that being a cosmetologist is more hardcore than you'd initially thought.
