Nail care is big business in the United States. With more than 50,000 manicurists and pedicurists in the country, you don't have to travel far to get your nails looking great [source: U.S. Bureau of Labor]. It's ironic, then, that getting your nails polished can sometimes leave them looking a little yellow. The pigments used in nail polish, particularly darker shades, can stain your nails over time.
The good news is that you can create whitening solutions with over-the-counter ingredients you may already have in your medicine cabinet. Hydrogen peroxide, baking soda and even denture cleaners are all popular choices for whitening yellowing nails. These solutions are gentle on your skin, meaning there's no harm in giving them a try. And if the results aren't quite what you hoped for, you can always polish your nails again or use a nail whitening pencil to lighten the tips, giving your nail a brighter look.
The next treatment on our list might not have so many tangential benefits, but in some cases, nothing else will do.
