Vegetable oil for dry nails
If you have dry, brittle nails, consider a solution in your pantry. Apply vegetable oil to your hands and cover them with plastic gloves overnight. That should work for a deep-moisturizing treatment.
Some home remedy fans also suggest soaking your hands in warm olive oil for 15-30 minute to moisturize your nails. To keep them from dying out, massage olive oil into your nails and cuticles daily
