Soaking your nails in lemon juice can whiten them. You can pour lemon juice in a small dish, or just apply lemons to your fingers. You can also use a paste made from baking soda and lemon juice,whitening toothpaste or white vinegar to get the same results.Allow the lemon juice to soak into your nails for 5 minutes. After that, wash hands and apply a hand lotion.
Make a nail care regimen and try to give your nails some rest by limiting the use of nail polish.
