Summarize the following:
Use a cotton ball soaked in nail polish remover to take off any nail polish currently on your nails. Simply rub each nail with the cotton ball until all of the polish has completely dissolved. In order to fully treat yellowed nails, the nails themselves have to be bare, with no layers of polish or varnish. Once all nail polish is removed, you can fully see the stained areas of your nails. Use a fine grit buffing board to lightly sand off the topmost layer of each of your nails. Gently rub the buffing board on the surface of your nail, moving the board straight back and forth, perpendicular to your nail. This light buffing can remove the top, stained layer of your nail, while exposing your unstained, clean nail underneath. Rotate your nail to the left and right to make sure you're also buffing the sides of your nail, not just the top, middle section. Only buff each nail for about 10 seconds. You want to be careful not to remove too many layers of your nail. Cut a lemon in half and rub the inside of the lemon onto your nails. Focus on rubbing the lemon on each nail for about 30 seconds to 1 minute. Once all of your nails have been rubbed with lemon, allow your nails to absorb the lemon juice and dry for about 10 minutes. After your nails have soaked in the lemon juice, apply a moisturizer to your hands and nails to prevent them from drying out. The lemon juice can lighten your nails much in the same way it can lighten hair when it is sprayed on and exposed to the sun. You could also squeeze lemon juice into a bowl and use a cotton ball to apply the juice directly to your nails. Mix 1 teaspoon of hydrogen peroxide with 2 tablespoon of baking soda until you have a paste-like mixture. Use an old, soft bristled toothbrush to apply and rub this paste onto your nails. Rub your nails with this mixture for approximately 2-3 minutes, and then rinse it off with clean water. Be sure to moisturize after using this solution. The hydrogen peroxide will dry out your hands. Consider adding a few drops of lemon juice into this paste to give the mixture even more whitening power. Alternatively, you could also create a soak by adding the hydrogen peroxide and baking soda mix into about 1 cup of water, and soaking your nails for about 5-10 minutes. Apply a thin layer of toothpaste containing hydrogen peroxide to all of your yellowed nails. Use your fingertips or a old, soft bristled toothbrush to rub the toothpaste all over the surface your nails. Allow the toothpaste to sit on your nails for approximately 10 minutes, and then rinse off the toothpaste with clean water. After rinsing off the toothpaste, apply lotion to your hands and nails to keep them hydrated. Drop 2-4 dissolving denture cleaning tables into a bowl of water, and soak your nails in the water for approximately 15 minutes. After 15 minutes, use a paper towel to dry your hands, and then rub on some lotion. You can soak your nails in this solution a couple times a month, but be sure you soak then when your nails are bare, and free from nail polish. If your nails are yellowed because of a nail fungus rather than constant use of nail polish, tea tree oil can help with the discoloration. Apply a couple drops of natural tea tree oil to each nail twice daily, and use your fingertips to massage the oil to all parts of your nails. Tea tree oil is a disinfectant and naturally fights fungus, which could help combat the yellowing of your nails. If you nails are severely yellowed, or the yellow coloring doesn't improve with any of these methods, you might have some sort of nail infection or yellow nail syndrome. A medical professional will be able to properly assess your situation, and may prescribe a medicated cream or supplements to treat your yellowed nails. Zinc supplements are commonly used to help treat yellowed nails.
