In which direction should you shape a nail to prevent splitting?

Shaping a nail from the outer edge toward the center is a preferred technique to prevent splitting. This method helps maintain the integrity of the nail, as it reduces stress on the nail structure. By working inward from the edges, you are less likely to weaken the nail's tip, which can be vulnerable to breaking or splitting.

This technique allows the edges to be smooth and encourages a strong, unified growth pattern from the base of the nail towards the tip, which is crucial for overall nail health. Additionally, this approach avoids excessive filing at the tip of the nail, which can create thin, weak spots that are more susceptible to damage.

Choosing this option is aligned with best practices in nail care that prioritize longevity and strength while promoting a well-groomed appearance. Other methods, such as filing in circular motions or from the center outward, may lead to uneven thickness or unnecessary stress points that can contribute to splitting or breaking.
