causes and symptoms of splitting and breaking of fingernails
Most cases of splitting nails are caused by moisture, according to the American Osteopathic College of Dermatology. Repeatedly wetting and drying your hands, and, by extension, your fingernails, can cause the nails to dry out. Too much moisture can also weaken the nails, softening them and causing them to peel.
Consider these simple tips: 1  Keep your fingernails dry. Repeated or prolonged contact with water can contribute to split fingernails. 2  Practice good nail hygiene. Keep your fingernails neatly trimmed, and round the tips in a gentle curve. 3  Avoid harsh nail care products. Limit your use of nail polish remover.  Apply a protective layer.
