What is the primary characteristic of onychorrhexis?

Onychorrhexis is primarily characterized by the splitting or brittleness of the nails. This condition typically presents as longitudinal ridges or splits running along the surface of the nail, making the nails appear fragile and prone to breaking. The condition can result from various factors, including trauma, overexposure to water, harsh chemicals, or underlying health issues.

Understanding onychorrhexis is essential for nail technicians as it impacts how clients care for their nails and the treatments that may be appropriate. While thickening of the nails, curvature of the nail plate, and discoloration can be associated with other nail conditions, they do not define onychorrhexis. Recognizing the signs and symptoms of this condition allows nail professionals to provide better service and advice to clients experiencing nail problems.
