What does onychophagy refer to?

Onychophagy refers specifically to the habit of biting one's nails. This term encompasses both the act of biting and the resulting condition of the nails, which can lead to various issues, such as damaged nail beds and increased susceptibility to infections. The habit is often associated with stress or anxiety and can be difficult to break. Understanding this term is crucial for nail technicians, as they may encounter clients who engage in onychophagy, needing special care or guidance on nail health and hygiene.

The other terms presented relate to different nail conditions and problems that don't accurately describe onychophagy. For instance, ingrown toenails are specific to toenails growing into the skin, cuticle growth pertains to the skin at the base of the nail, and nail infections involve infectious processes affecting the nail or surrounding tissue. None of these definitions align with the concept of nail biting.
