What are wavy nail ridges that result from uneven growth often referred to as?

Wavy nail ridges that result from uneven growth are known as corrugations. This term specifically describes the undulating appearance and texture of the nails caused by fluctuations in growth rates, which can occur due to various factors, including health conditions, nutritional deficiencies, or trauma to the nail matrix.

Understanding this term is important for nail technicians, as it helps them recognize specific nail conditions that may need attention or a different approach during manicures or pedicures. Ensuring clients are informed about their nail health is a key aspect of nail care.

Other terms in the options relate to different concepts; for instance, eggshell nails refer to nails that are thin and fragile, while onyx is the scientific term for nails overall. Filings refer to the debris produced from filing nails, not a condition related to nail growth. Each term has its distinct meaning, but corrugations specifically address the phenomenon of irregular, wavy nail ridges.
