Which of the following is a sign of healthy nails?

A sign of healthy nails is characterized by a smooth surface. Healthy nails should appear even, without visible ridges, grooves, or irregularities. A smooth nail surface indicates that the nail is well-hydrated and free from damage or disease, which allows for proper growth and maintenance.

When nails are smooth, they reflect light evenly, giving them a healthy shine. This quality can be an indicator of overall health as well. In contrast, rough textures can suggest a lack of moisture or the presence of fungal infections, while frequent splitting can point to underlying issues such as nutritional deficiencies or improper care. Consistent shape is also appreciated, but it is the smoothness of the nail that is most directly tied to its health.
