Filing from the center outwards is a recommended practice when shaping nails because it promotes a uniform shape and minimizes the risk of damaging the nail structure. This technique helps to ensure that the nail maintains its integrity as it is shaped, as it distributes pressure evenly across the nail rather than concentrating it in one area. By starting at the center, the nail tech can create a balanced outline and avoid creating weak points or splits that could lead to breakage.

Using other methods, such as filing in a circular motion exclusively, may create uneven edges or an unnatural shape, while filing back and forth can lead to nail damage and increased risk of friction that may weaken the nail. Additionally, consistently using a coarse file can also harm the nails by causing excessive wear or injury to the nail plate. Therefore, the method of filing from the center outwards is not only more effective for shaping but also helps maintain the overall health of the nails.
