On their own, it's important to keep your nails healthy and in good condition. The U.S. National Library of Medicine offers these suggestions:
- Don't bite your nails, or pick or tear at them. If you have trouble stopping these behaviors, talk with your doctor.
- Clip hangails regularly.
- Cut your toenails in a straight line.
- Wear comfortable shoes that don't squeeze the toes.
- Keep fingernails short.
- Take the vitamin biotin to help strengthen brittle nails, and apply a coat of clear nail polish that contains protein.
