You use your fingernails daily. However, you likely take it for granted that your fingernails have certain characteristics which make them useful. Nails are great for scraping, scratching, picking, prying, gripping, sorting, and even adornment. All is well until our nail health begins declining. One of the most common types of nail abnormalities is brittleness. The resulting changes in the fingernails are often referred to as brittle nail syndrome.
