How long do you keep hair dye on your head?

3-5 days, and even longer for nail stains. One Word. BLEACH. Put it on an old rag and rub it on your skin. Viola!

If you're asking "how you get hair dye off skin" that means you're probably sitting at home, late for an outing, and desperate. And the "buy stain remover next time" advice probably just ticks you off. Just get the bleach out - your skin will be fine as long as you rinse it off immediately.

I have dark hair and have had no luck with nail polish remover, tooth-paste, vaseline, OR vinegar. Save yourself the headache. And for nails (like when your nails cut the ends of the gloves and the hair dye stains your fingertips) - just polish over with a dark nail polish!

I always polish my nails (no need to be neat) before I dye my hair, so if/when my fingertips get stained, the nail polish remover will atleast remove the nail stains (because they're on top of the polish), and the bleach will take care of the rest.

Previous answer:depending on the dye, between 2-5 days. the easiest way to get it off fast, though, is nail polish remover. just don't get it too close to your eyes! if you don't want to use that, make-up remover should work okay.
