Dry, flaking or peeling nails can be caused by a variety of both external and internal reasons, including trauma to the nail or a vitamin deficiency. It can also be caused by excess moisture, the application of false nails or a diet deficient in iron.
Often, flaking or dry nails can be treated with a home remedy and do not require medical attention. These treatments can consist of taking an iron supplement, minimizing prolonged exposure to water and avoiding using the nails as tools. If nails are dry, peeling and are causing severe pain or bleeding, seek medical attention, as this can be a symptom of a more serious internal cause.
