The formation of ribbed nails is an essential indicator of underlying health issues. Since fingernails are always visible, even minor structural alterations are readily apparent. This is beneficial because the appearance of the nail plate serves as an indicator of the overall condition of the body.

For instance, many individuals encounter a scenario wherein the nail is wavy. These narrow lines extend from the cuticle to the distal end of the nail and may appear elevated or depressed.

As experts have noted, this feature is often inherent in adults but can also manifest in children.

“Although vertical ridges are usually benign, they may occasionally indicate more serious underlying conditions, such as iron deficiency,” scientific literature states.
