Trimming nails is the process of cutting the hard outer covering of fingers and toes to maintain hygiene and prevent discomfort. Regular trimming helps avoid issues like ingrown nails and hangnails. It is typically done using tools such as nail clippers or scissors designed specifically for this purpose. To trim nails properly, it is best to do so after a shower or bath when they are softer. Cut straight across the nail to prevent ingrown nails, and avoid cutting too close to the skin. After trimming, smooth the edges with a nail file for a neat finish.
