What is the correct technique for filing a nail?

The technique of filing a nail from corner to center is widely recommended because it helps in maintaining the nail's natural shape and prevents splitting or breaking. By starting at the corners, you can control the curve of the nail and create a more rounded or squarish shape, depending on the client's preference. This approach minimizes the risk of causing damage to the nail plate that can occur when filing in a straight line or side-to-side.

Filing from the corners toward the center allows the nail technician to shape the nail gradually and uniformly, which is crucial for achieving aesthetically pleasing results. This method also distributes pressure evenly across the nail and avoids excessive wear that can result from improper filing techniques. Keeping this in mind, it is essential for manicure professionals to master this particular filing technique as it contributes to the health and appearance of the nails.
