What type of filing should be avoided to prevent injury to the nail?

Filing back and forth aggressively can cause significant damage to the nail structure. This aggressive technique can lead to splitting, tearing, and weakening of the nail plate, which may result in pain and potential injury. A more appropriate filing technique involves using a gentle, consistent motion, preferably in one direction, which helps to maintain the integrity of the nail while reducing the risk of fraying or creating weak spots. By avoiding aggressive filing methods, nail technicians can ensure the health of their clients' nails and prevent any adverse effects that may arise from improper filing techniques.
