What is the proper technique for filing nails?

Filing nails using a back and forth motion can lead to splitting or damaging the nails, as this technique does not create a smooth edge. Instead, the proper method for filing is to use long, gentle strokes in one direction, typically from the outside edge toward the center of the nail. This approach helps to maintain the integrity of the nail and reduces the risk of fraying or breakage.

While some practices involve other methods, such as circular motions or soaking nails, these are less effective for maintaining nail health. Addressing the other options: circular motions can create uneven edges, and focusing only on the tips or filing after soaking does not address all areas of the nail adequately. Using a one-way filing technique is universally recommended for achieving well-groomed nails while minimizing potential damage.
