What is the correct way to file natural nails?

Filing natural nails in one direction is considered the best practice because it helps to prevent splitting and damage to the nail. When filing in multiple directions, the friction and pressure can weaken the nail structure, leading to fraying or tearing. This method maintains the integrity of the nail and promotes healthy growth. Additionally, using a gentle, consistent motion allows for better control and precision in shaping the nail.

Other methods, such as filing in a circular motion or using a coarse file, can lead to undesirable results. Circular motions can create uneven edges or contribute to nail breakage, while coarse files can be too abrasive and may damage the delicate keratin structure of natural nails. Adopting a careful and methodical approach by filing in one direction ultimately yields the best results for maintaining strong, healthy nails.
