Brittle nails are a common condition where the nails become weak, dry, and prone to breaking or splitting. This can occur due to various factors, including environmental conditions, nutritional deficiencies, or underlying health issues. People with brittle nails may notice that their nails chip easily or have a rough texture. Several factors can contribute to brittle nails, such as frequent exposure to water, harsh chemicals, or lack of essential nutrients like biotin and zinc. Maintaining proper nail care, including moisturizing and avoiding excessive exposure to irritants, can help improve nail strength and appearance.
