The stains remain until the nail grows out and only disappear if they don't continue to smoke. Wear protective gloves. Hair stylists, nurses and other health care workers who work with dyes or chemical solutions may end up with stained nails, say women dermatologists. If you work with strong chemicals, always wear protective gloves. If you've quit smoking and stopped coloring your nails, and they're still discolored, consider seeing a doctor.
Some medications can cause changes in nail pigmentation.
