Which characteristic best describes a healthy nail?

A healthy nail is characterized by several specific qualities that reflect its vitality and proper growth. The correct choice describes a healthy nail as smooth, curved, free from hollows or wavy ridges, and possessing flexibility. Additionally, it should have a translucent appearance and a pinkish color, indicating good blood circulation beneath the nail bed.

Smoothness is important because it indicates that the nail is not damaged, while a curved shape suggests proper growth. The absence of hollows or wavy ridges is essential, as these irregularities can signal underlying health issues or damage. Flexibility allows the nail to withstand everyday wear and tear without breaking, and a translucent appearance helps display the health of the nail bed.

Lastly, the pinkish color is a sign of healthy blood supply, vital for nail growth and overall health. In contrast, characteristics like roughness, brittleness, pitting, and ridges indicate potential problems or damage to the nails, highlighting why these features do not describe a healthy nail.
