Onychorrhexis is defined as which nail condition?

Onychorrhexis is recognized specifically as a condition characterized by brittle nails that exhibit lengthwise ridges. This manifests as thin, fragile nails that can break easily, leading to a textured appearance that may include linear ridges running along the length of the nail plate. This condition can result from various factors, including environmental influences, nutritional deficiencies, or underlying health issues.

Understanding this condition is vital for a manicurist, as it informs them about how to properly care for clients with onychorrhexis, such as recommending hydrating products, avoiding harsh chemicals, or advising on protective nail treatments to improve their condition.
