Onychorrhexis Definition

Onychorrhexis is a term used to describe a condition characterized by brittle or weakened nails, specifically the toenails. It refers to the presence of longitudinal ridges, lines, or grooves on the nails. These ridges can be shallow or deep, and may also be accompanied by splitting or cracking of the nail. Onychorrhexis can be caused by various factors such as nutritional deficiencies, certain medical conditions, repetitive trauma, excessive use of harsh chemicals, and aging. Treatment typically involves addressing the underlying cause, maintaining proper nail care, and using moisturizers or protective coatings to improve the health and strength of the nails.
