What grit file should be used on natural nails to prevent damage?

• A. 180 grit
• B. 240 grit
• C. 320 grit
• D. 600 grit

Answer: (B)

When shaping natural nails, you want an abrasive level that removes a little material without injuring the nail plate. A moderate grit around 240 hits that balance well. It’s rough enough to shape the edge efficiently, but gentle enough to minimize thinning, micro-tears, or splitting that can come from harsher grits. A rougher option, like 180, can gouge and weaken the nail. A finer option, like 320, is gentler but may take longer to shape, while 600 is typically used for smoothing or buffing rather than shaping. Using the 240 grit and filing in one direction from the outer edge toward the center helps preserve the natural nail and create a clean, safe edge.
