What is the recommended technique for filing nails?

Filing nails in one direction is the recommended technique because it helps to prevent damage to the nail bed and minimizes the risk of splitting or tearing the nails. When filing in a single direction, the filing action creates a smoother edge and reduces friction that can weaken the nail structure. This method encourages healthier nails and provides a more polished appearance.

Other filing techniques, such as filing in multiple directions or filing back and forth quickly, can lead to jagged edges and increase the likelihood of nail breakage. These methods create more trauma to the nail and can compromise its integrity. Filing only the tips of the nails may not address the overall shape and length, leading to uneven or poorly shaped nails. Therefore, focusing on filing in one direction is the best practice for maintaining nail health and achieving desired nail aesthetics.
