What are hangnails most commonly caused by?

Hangnails are most commonly caused by dryness and neglect to the nails. When nails are dry, they can become brittle and may crack or split, leading to the formation of hangnails. This condition is often exacerbated by insufficient moisture and care, and environmental factors such as lack of humidity can further contribute to the problem.

Regular moisturization and proper nail care can help prevent dryness, keeping both the skin around the nails and the nails themselves healthy. While other options such as not washing hands frequently or using lotions may have a role in general nail health, they are not primary factors in the development of hangnails. Proper hydration and maintenance of the nails and surrounding skin are key in avoiding this condition.
