What is the typical cause of a hangnail?

• A. Excessive moisture
• B. Dry skin or trauma
• C. Fungal infections
• D. Allergic reactions

Answer: (B)

A hangnail is commonly caused by dry skin or trauma. When the skin surrounding the nail becomes dry, it can lead to small, jagged pieces of skin that can separate and protrude from the nail edge. Trauma, such as biting or picking at the skin around the nails, can also contribute to the formation of hangnails. This condition is more prevalent during colder months or in individuals who do frequent hand washing or exposure to harsh environments without sufficient moisturization.

While excessive moisture can lead to other nail-related issues, it is not typically associated with the formation of hangnails. Fungal infections and allergic reactions can cause other skin or nail disorders, but they are not the primary reasons for the appearance of hangnails. Understanding the role that dry skin and trauma play is crucial in identifying preventive measures, such as maintaining proper hydration and avoiding harsh handling of the skin around the nails.
