Q: Which nail file is best for natural nails?
A: A finer grit is kinder to natural nails. Coarse grits are designed for artificial tips and will shred a natural free edge if used to shape.
Q: Will using a nail file damage my natural nails?
A: Not if you file in one direction rather than sawing back and forth. The back-and-forth motion is what causes splitting and peeling. Keep a light touch and let the file do the work.
Q: How often should I file my nails?
A: Once a week suits most people, or whenever you notice a rough edge. Filing more often than your nails grow will gradually thin the free edge.
