What does a normal, healthy nail surface look like?

A normal, healthy nail surface is characterized as shiny and smooth. This luster indicates that the nail is well-hydrated and free from any damage or disease. A healthy nail will reflect light, which contributes to its shiny appearance, and it should be free of ridges, pits, or any discoloration. The smoothness also suggests that the keratin layers are intact and properly organized, allowing for strength and flexibility. Maintaining this ideal condition is essential for overall nail health and is often indicative of a person's general well-being.

In contrast, options that describe a nail as rough, dull, uneven, brittle, or transparent suggest various health issues or damage that can arise from environmental factors, improper care, or overall health conditions. Such characteristics typically indicate that the nails are not in optimal condition.
