What appearance indicates a healthy nail surface?

A healthy nail surface is characterized by a shiny and smooth appearance. This reflects proper hydration and care, indicating that the nails are well-maintained and free from damage or fungal infections. A shiny surface indicates that the nail is flexible, strong, and free from surface irregularities.

In contrast, other appearances such as deep grooves suggest trauma or health conditions that could affect nail growth. A flaky and dull surface may indicate lack of moisture, vitamin deficiencies, or damage, while discoloration and brittleness commonly point to underlying health issues or improper care. Therefore, the criteria for a healthy nail surface include smoothness and shine, marking option B as the correct representation of nail health.
