What effect does improper filing have on nails?

Improper filing can lead to significant damage to the nails, specifically causing splitting and other forms of injury. When nails are filed incorrectly, it often results in uneven edges or fraying, which weakens the nail structure. This can create weak points where the nail is prone to breakage or splitting, ultimately compromising its integrity. Such damage may not only affect the appearance of the nails but can also lead to discomfort or more serious nail health issues. Therefore, understanding the proper techniques for filing is crucial for maintaining both the health and aesthetics of nails.
