What is the correct way to file natural nails?

The proper technique for filing natural nails is to file from the side toward the center. This method helps to create a smooth edge without damaging the nail. Filing in this direction minimizes the risk of splitting or tearing the nail and promotes a more consistent shape.

Using a back-and-forth motion can lead to rough edges and potentially weaken the nail structure, as it can create friction that is harmful to the nail. Filing from tip to base in a straight line may not allow for the necessary shaping of the nail, and could lead to a blunt edge rather than a naturally curved finish. Additionally, circular motions are not effective as they don't provide a clean and uniform result. Therefore, the technique of filing from side to center is the most effective way to ensure the health and appearance of natural nails.
