Which abrasive file would you use to shape a weak natural nail?

  1. 80 grit

  2. 100 grit

  3. 180 grit

  4. 240 grit

The correct answer is: 240 grit

Using a 240 grit abrasive file is ideal for shaping weak natural nails because it is finer and less abrasive compared to the other options. This grit level helps to smooth the edges and gently refine the nail surface without causing damage or excessive thinning. Weak natural nails require careful handling to prevent splitting or breaking, and a finer grit allows for a more controlled approach. The higher the grit number, the smoother the finish, which is critical for maintaining the integrity of the nail. Therefore, a 240 grit file is appropriate for achieving a polished look while ensuring the health of the natural nail is prioritized. Other grits, such as 80 or 100, are too coarse and could lead to considerable wear on the nails, while a 180 grit is still on the coarser side and may not provide the gentleness needed for weak nails.
