What condition is described as dry and brittle nails that tend to break easily?

The condition characterized by dry and brittle nails that are prone to breaking is known as onychorrhexis. This defect manifests as longitudinal ridges on the surface of the nails, contributing to their fragility. Often caused by various factors, including environmental influences or underlying health issues, onychorrhexis can significantly impact nail health.

When nails are brittle, they may split or break more easily, making this condition particularly notable. It's important to recognize this condition in manicure and pedicure practices, as understanding the specific needs of clients with brittle nails is vital for proper treatment and care.

In contrast, other conditions mentioned do not primarily describe the same symptoms. Hang nails are torn pieces of skin around the nails, koilonychia refers to a spoon-shaped nail, and lamella dystrophy relates to a separation of nail layers, none of which directly correlate with the brittleness and breaking tendency that onychorrhexis exhibits.
