Which of the following is a sign of a healthy nail?

A healthy nail is characterized by uniform thickness and a smooth surface. These qualities indicate that the nail is well-hydrated, properly nourished, and free from infections or underlying health issues. The absence of rough textures or irregularities reflects good nail care practices and overall nail health.

In contrast, rough textures suggest damage or external factors that have negatively impacted the nail, while discoloration can signal possible health concerns or fungal infections. Frequent breaking may indicate weakened nails due to lack of moisture, nutritional deficiencies, or other health-related issues. Therefore, the presence of uniform thickness and a smooth surface is a clear indicator of a well-maintained and healthy nail.
