What factor is important to ensure when drilling nails?

The correct factor to ensure when drilling nails is the correct angle of the drill. When using a drill for nail enhancement or maintenance, maintaining the appropriate angle is crucial for achieving optimal results. A proper angle helps to prevent damage to the natural nail and ensures that the product is applied evenly and adheres well.

Drilling at the wrong angle can lead to uneven surfaces, potential tearing, or weakening of the nail structure, which could compromise the integrity of the enhancement. This level of precision is key in professional nail care, as it not only affects the aesthetic outcome but also the health of the nail.

While other factors like hydration, the type of polish, and nail length are important in nail care and aesthetics, the angle at which the drilling is performed directly influences the effectiveness and safety of the procedure.
