Nail strengthening refers to various methods and products designed to improve the durability and resilience of nails. Weak or brittle nails can break easily, leading to discomfort and an unkempt appearance. Common solutions include nail hardeners, biotin supplements, and moisturizing treatments that help maintain nail health. Many factors contribute to nail weakness, such as nutritional deficiencies, excessive exposure to water, and harsh chemicals. Regularly applying nail polish or using nail care products can also help protect and strengthen nails. Maintaining a balanced diet rich in vitamins and minerals is essential for promoting overall nail strength.
