Which practice is important to avoid hangnails?

Moisturizing cuticles regularly is important for avoiding hangnails because it helps to keep the skin around the nails soft and hydrated. Hangnails occur when the cuticle or surrounding skin becomes dry and brittle, leading to splits or tears that can form hangnails. By maintaining adequate moisture in the cuticle area, the skin remains pliable and is less susceptible to damage. Regular moisturizing creates a barrier that protects against environmental factors that can dry out the skin, such as cold weather, frequent hand washing, or exposure to harsh chemicals.

While the other practices mentioned may have their own benefits for nail care, they do not directly address the prevention of hangnails in the same way that regular moisturizing does.
