What are signs of a healthy nail?

A healthy nail typically exhibits a smooth surface and a pinkish color. The smooth surface indicates that the nail is well-maintained, without any ridges, bumps, or indentations that can be signs of underlying health issues or trauma. Additionally, the pinkish color results from the nail bed's healthy circulation, which supports nail growth and contributes to an overall appearance of vitality and wellness.

In contrast, brittle or thick nails, rough edges, or discoloration suggest various problems such as dehydration, nutritional deficiencies, or fungal infections, indicating that the nail is not in an optimal condition. These features do not align with the characteristics of healthy nails.
