What is a characteristic of a healthy nail?

A characteristic of a healthy nail is flexibility. Healthy nails should be somewhat flexible, allowing them to withstand daily activities without breaking or splitting easily. This flexibility indicates that the nail is receiving adequate moisture and nutrients, which contributes to its overall strength and health.

In contrast, dull nails may suggest a lack of moisture or improper care, while ridged nails can be a sign of various underlying health issues or nutrient deficiencies. Blue nails, often indicative of poor circulation or oxygenation in the body, signify a potential health concern. Therefore, flexibility is a strong indicator of nail health and resilience.
