What often causes hangnails?

Hangnails are typically caused by dry skin or improper nail care. When the skin around the nail becomes dry, it can lead to cracks and splits that create hangnails. Factors that contribute to dry skin include environmental conditions, frequent hand washing, or the lack of moisturizing. Proper nail care, which includes moisturizing the cuticles and avoiding biting or picking at the skin around the nails, is crucial in preventing hangnails. Maintaining healthy nails and skin involves not just proper grooming practices but also regular hydration of both the nails and surrounding tissue.

While excessive moisture exposure, low-quality nail products, and allergies can also affect the nails and skin, they don't directly lead to the formation of hangnails as consistently as dry skin and inadequate care do. For instance, excessive moisture can sometimes soften skin and nails, potentially leading to other issues, but it typically doesn't cause hangnails.
