What term describes nails that have been bitten?

The term that describes nails that have been bitten is onychophagy. This condition is the result of nail-biting behavior, which can lead to the shortening and irregularities in the structure of the nails. Onychophagy is particularly significant because it not only affects the appearance of the nails but can also cause damage to the surrounding skin and increase the risk of infections. Understanding this term is essential in the field of cosmetology, as it highlights a common issue that can affect clients' nail health and aesthetics.

In contrast, the other terms refer to different nail conditions. Onychomycosis is a fungal infection of the nails, leukonychia refers to white spots or discoloration of the nails, and onychorrhexis describes split or brittle nails. Each of these conditions has distinct causes and implications for treatment and care, but none address the behavior of nail-biting specifically.
