Which technique is recommended for filing natural nails?

Filing natural nails in one direction is the recommended technique because it minimizes the risk of splitting or damaging the nail. When you file in a single direction, it helps to maintain the integrity of the nail's structure and prevents fraying at the edges, which can occur if you file back and forth.

This approach not only promotes healthier nails but also allows for better precision in shaping. Additionally, it creates a smoother edge that is less likely to snag or break. Overall, using this method can result in healthier and more aesthetically pleasing nails, aligning with best practices in nail care.
