What is referred to when nails are split or brittle with a series of lengthwise ridges?

The condition characterized by nails that are split or brittle, featuring a series of lengthwise ridges, is known as onychorrhexis. This term specifically describes the brittleness and splitting of the nails that can occur for various reasons, such as environmental factors, nutritional deficiencies, or underlying health issues.

Recognizing onychorrhexis is important for nail technicians since it may indicate that the client requires specific nail care or modification in their treatment to avoid further damage. It's vital to assess the state of the nails to provide appropriate services and recommendations for maintaining nail health.

Other terms mentioned refer to different nail conditions: onycholysis involves the separation of the nail plate from the nail bed; koilonychia describes a spoon-shaped nail, often associated with iron deficiency; and leukonychia indicates white spots on the nails. Understanding the distinctions among these conditions helps in delivering tailored care to clients.
