What causes grooves in the nail when using the e-file?

Grooves in the nail can occur when the e-file is held at the wrong angle. When an e-file is not positioned properly, it may create uneven pressure on the nail surface, leading to grooves or indentations. The e-file needs to be held at an optimal angle that allows for smooth, consistent contact without applying too much pressure or causing friction that would damage the nail bed.

Proper technique is crucial in ensuring that the e-file glides evenly across the nail without causing harm. By maintaining the correct angle, the technician can avoid the formation of grooves, achieving a more polished and healthy nail surface. This not only improves the appearance of the nail but also upholds the integrity of the natural nail structure.
