Hang nails are caused by dry cuticles and carelessness in removing them. This is because dry cuticles can make the skin around the nails more prone to tearing or peeling, leading to the development of a hang nail. Filing the nail too much can also contribute to this problem by causing the nail to weaken and become brittle. Injury to the base of the nail and a contagious virus are not the main causes of hang nails and are less likely to occur.
