Nails that split or peel
Overview
Nail splitting or peeling occurs when fingernails or toenails develop cracks, layers that separate, or flaking of the nail surface. This common nail condition can affect one or multiple nails and may cause the nail to appear rough, brittle, or damaged.
Common Causes
Split or peeling nails are commonly caused by frequent exposure to water and harsh chemicals from activities like dishwashing or cleaning without gloves. Dry conditions, cold weather, and aging naturally reduce nail moisture and flexibility, making them more prone to damage. Nutritional deficiencies, particularly in biotin, iron, or protein, can weaken nail structure over time. Frequent use of nail polish remover, aggressive manicuring, or nail biting can also strip away protective oils and damage the nail surface.
Severity Levels
Mild: Occasional splitting or peeling affecting one or two nails with minor surface flaking that doesn't interfere with daily activities.
Moderate: Regular splitting or peeling across several nails with noticeable layers separating, causing some discomfort during routine tasks like typing or handling objects.
Severe: Frequent and extensive splitting or peeling affecting most nails with deep cracks, significant pain, and difficulty performing everyday activities due to nail damage.
Medical Attention
Seek medical attention if nail splitting affects multiple nails, persists despite proper nail care, or is accompanied by pain, swelling, or signs of infection. Consult a healthcare provider if you notice sudden changes in nail texture, color changes, or if the splitting interferes with daily activities. Professional evaluation is recommended when over-the-counter treatments haven't improved the condition after several weeks.
