When using an electric file to shorten a nail enhancement, at what angle should the file be held?

When using an electric file to shorten a nail enhancement, the file should be held at a 90-degree angle to ensure precision and control during the filing process. Holding the file vertically allows for even removal of the product and helps in maintaining the natural shape of the nail. This position prevents unnecessary stress on the nail and reduces the risk of causing damage to the natural nail bed, especially when working on enhancements.

Maintaining this angle also provides better visibility and accessibility while working, enabling the technician to monitor the nail enhancement closely for a uniform finish. Other angles, such as a 45-degree angle or a 10-degree angle, could result in uneven filing or difficulty in achieving the desired length and shape. A 180-degree position could lead to improper filing techniques and increased risk of harm to both the enhancement and the natural nail. Therefore, the 90-degree angle is the optimal choice for achieving both efficiency and safety in this process.
