What can cause brittle nails?

Brittle nails can be primarily attributed to environmental factors and nutritional deficiencies. Environmental elements such as harsh weather conditions, exposure to chemicals, and frequent contact with water can strip the nails of their natural moisture, leading to increased brittleness. Additionally, a diet lacking essential nutrients, particularly vitamins and minerals such as biotin, calcium, and certain proteins, can impair nail health. When the body does not receive adequate nutrition, nails often become weak and brittle due to poor structural integrity.

While excessive polishing, overuse of nail products, and genetic conditions may also contribute to nail issues, they do not represent the primary causes of brittleness across the broader population. In this context, focusing on nutrition and environmental factors provides a comprehensive understanding of how to maintain nail health and prevent brittleness effectively.
