Fingernail care: Do's and don'ts

To keep your fingernails looking their best:

• Keep fingernails dry and clean. This prevents bacteria from growing under your fingernails. Repeated or prolonged contact with water can contribute to split fingernails. Wear cotton-lined rubber gloves when washing dishes, cleaning or using harsh chemicals.
• Practice good nail hygiene. Use a sharp manicure scissors or clippers. Trim your nails straight across, then round the tips in a gentle curve.
• Use moisturizer. When you use hand lotion, rub the lotion into your fingernails and cuticles, too.
• Apply a protective layer. Applying a nail hardener might help strengthen nails.
• Ask your doctor about biotin. Some research suggests that the nutritional supplement biotin might help strengthen weak or brittle fingernails.
