What is the technical term used for "nail disease"?

The term "onychosis" refers specifically to a nail disease or condition affecting the nail and its surrounding area. This term encompasses a variety of nail disorders, including changes in the nail's appearance, structure, and health. Recognizing this term is important for professionals in the field of nail care, as it allows them to identify and address various nail-related issues that clients may present.

In contrast, "onyx" is a term used to describe the nail itself but does not denote any disease or condition. "Eponychium" refers to the cuticle area at the base of the nail that overlaps the nail plate, which is not related to disease. "Onychophagy" pertains to the habit of nail-biting, which again does not indicate a nail disease but rather a behavioral issue. Understanding these distinctions aids in the assessment and proper care of clients' nails, ensuring that any underlying conditions can be effectively managed.
