What is a sign of an unhealthy nail condition?

A sign of an unhealthy nail condition is indicated by color changes in the nails. Healthy nails typically maintain a consistent color, which helps signify good blood circulation and overall health. Any deviation from the normal nail color—such as white spots, yellowing, or darkened areas—can indicate underlying issues, such as fungal infections, nutritional deficiencies, or systemic health problems.

In contrast, an even nail surface suggests a smooth texture and indicates proper care or nail health. Normal growth refers to the standard rate at which nails grow and does not necessarily indicate a problem. Similarly, a clear and intact cuticle is a sign of proper nail care, as it protects the nail matrix and helps prevent infection. Thus, the presence of color changes serves as a more specific indicator of potential unhealthy nail conditions.
