What characteristic might indicate healthy nails?

A firm and smooth texture in nails is a strong indicator of healthy nails. Healthy nails typically possess a consistent appearance and feel that suggests proper nutrition and care. A firm texture indicates that the nails are well-hydrated and have not been overly exposed to harsh chemicals or trauma, while a smooth surface shows that the cuticle and keratin layers are intact and functioning properly. This characteristic suggests good circulation and the absence of fungal infections or other conditions that could compromise nail health. Maintaining nails in such a condition helps to prevent common issues like splits, cracks, or infections, and reflects overall health and well-being.
