Summarize this article in one sentence.
Olive and coconut oil are great natural moisturizers. They can also help to heal any cracks or cuts in your hands due to dryness. Apply a generous amount of olive or coconut oil to your hands. Then, rub in the oil well and let it dry. Re-apply the olive or coconut oil as necessary. If you want to lock the moisture of the oil into your skin, put small plastic bags over your hands once the oil has been applied. Clean wool socks or cloth gloves would also work well. Keep them on for 30 minutes or overnight. Doing this will lock the moisture of the oil into your hands as the oil dries. Shea butter is another good natural remedy for hands that are in desperate need of moisturizing. Apply the shea butter to your hands and let the butter seep into your skin. You can apply the shea butter to your hands as needed throughout the day. You can buy shea butter online or at your local health food store. The lactic acid in milk acts as a natural exfoliator. The amino acids and silica in oats are good for hydrating your skin. Combine one part milk with one part rolled oats in a bowl big enough to fit your hands. Then, place your hands in the milk and oats. Let your hands soak for 10-15 minutes. After 10-15 minutes, gently rinse your hands off in lukewarm water. Your hands should feel soft and less dry.

Summary:
Apply olive or coconut oil to your hands. Use shea butter on your hands. Soak your hands in milk and oats.
