Dermatologists’ tips for healthy nails
Taking the time to properly care for your nails isn’t just about how they look; nail health reflects our overall health.
To keep your nails healthy, follow these tips from board-certified dermatologists.
Nails reflect our overall health, which is why proper nail care is so important. Here are dermatologists’ tips for keeping your nails healthy:
- Keep nails clean and dry. Bacteria and fungi thrive in a moist environment. By maintaining clean, dry nails, you prevent bacteria from growing underneath your nails. 
- Cut nails straight across. Use sharp nail scissors or clippers. Round the nails slightly at the tips for maximum strength. 
- Keep nails shaped and free of snags by filing with an emery board. 
- Do not bite fingernails or remove the cuticle. Doing so can damage the nail. 
- Do not use your nails as a tool, such as opening pop cans. Doing so can cause damage, like chipping, splitting, or lifting of the nail bed. 
- Protect your nails from water. Too much water exposure can weaken your nails, causing them to split, peel, or break. To prevent this, wear gloves when cleaning or washing dishes, and make sure to moisturize after hand washing. 
- Trim toenails regularly. Keeping them short will minimize the risk of trauma and injury. 
- When toenails are thick and difficult to cut, soak your feet in warm salt water. Mix one teaspoon of salt per pint of water and soak for 5 to 10 minutes. 
- Avoid “digging out” ingrown toenails, especially if they are infected and sore. If you are suffering from an ingrown toenail, see a dermatologist for treatment. 
- Wear shoes that fit properly. Also alternate which pair of shoes you wear each day. 
- Wear flip flops at the pool and in public showers. This reduces the risk of infections caused by a fungus that can get in your toenails. 
If your nails change, swell, or cause pain, see your dermatologist because these can be signs of serious nail problems. If you have diabetes or poor circulation, it’s especially important to seek treatment for any nail problems. If you have questions or concerns about caring for your nails, see a board-certified dermatologist.
