Which abrasive file is recommended for shaping a weak natural nail?

120 grit
180 grit
240 grit
320 grit

The correct answer is: 240 grit

Choosing the right abrasive file for shaping a weak natural nail is crucial for maintaining its health and integrity. A 240 grit file is ideal for this purpose because it provides a gentle touch that can effectively shape the nail without causing excessive damage. The finer grit level, such as 240, is less abrasive, making it suitable for delicate or weak nails, as it reduces the risk of splitting or breaking. Grain size is essential when working with weak nails; coarser grits (lower number) are more aggressive and can remove more material quickly, which is not advisable for weak nails. Finer grits, like 180, while still somewhat usable, may not offer the same gentleness as 240 grit. Similarly, the 320 grit file, while very fine and gentle, may not be as effective in shaping as the 240 grit, which strikes a better balance between gentle shaping and effectiveness. Overall, the 240 grit file is the appropriate choice because it allows for careful and precise shaping while minimizing the risk to the natural nail's health.
