Nail health refers to the condition and appearance of your nails, which can indicate overall health. Healthy nails are typically smooth, strong, and free from discoloration or spots. Factors such as nutrition, hygiene, and exposure to harsh chemicals can affect nail health. A balanced diet rich in vitamins and minerals, particularly biotin, zinc, and protein, supports strong nails. Maintaining good nail health involves regular trimming, moisturizing, and avoiding excessive use of nail polish or artificial nails. It's also important to protect your nails from trauma and to keep them clean to prevent infections. If you notice persistent changes, consulting a healthcare professional may be necessary.
