What is the medical term used for a condition that affects the nails?

The term "nail disorder" is the appropriate medical terminology used to describe any condition that affects the nails. This encompasses a variety of issues, such as fungal infections, nail psoriasis, ingrown nails, and more. A "disorder" in a medical context refers to a disturbance in the normal functioning of the body or its parts, which in the case of nails includes changes in color, texture, shape, or growth patterns.

While "nail condition" may seem like a suitable option, it is less commonly used in clinical settings compared to "nail disorder," which has a specific association with pathological states that affect the nails. Similarly, "nail injury" specifically refers to trauma or physical damage to the nail rather than a broader range of issues affecting nail health. This distinguishes "nail disorder" as a term that is more clinically accurate and widely recognized in both health and cosmetic fields related to nails.
