What is a crucial rule when filing the natural nail?

When filing the natural nail, the most essential practice is to avoid filing into the corners of the nail. This method is crucial for preventing damage to the nail structure, which can lead to splitting, tearing, or ingrown nails. The corners of the nail are more prone to breakage, and excessive filing in that area can also cause discomfort and increase the likelihood of infection.

Filing should be done in a gentle, controlled manner, usually following the natural shape of the nail and moving in one direction, rather than aggressively filing back and forth. Using an appropriate file, rather than just any coarse file, is important for maintaining the integrity of the natural nail. Additionally, filing on wet nails can lead to more damage as wet nails are more pliable and prone to bending and splitting. Thus, focusing on the proper technique, especially avoiding the corners, enhances nail health and promotes a neater, longer-lasting manicure.
