What practice involves excessively roughing up the nail plate?

The practice of excessively roughing up the nail plate is referred to as overfiling. This process occurs when a technician files the nail plate too aggressively, which can lead to thinning of the nail and potentially cause damage to the natural nail. Overfiling disrupts the nail's natural health and can result in issues like sensitivity, inflammation, and even nail separation in severe cases.

It's important for nail technicians to understand the proper techniques for preparing the nail plate without causing harm. This includes using the appropriate grit on files and buffers, as well as ensuring that the filing is done in a controlled and gentle manner, preserving the integrity of the natural nail. Practicing proper filing techniques helps maintain the health of the nails while still achieving the desired results for manicures and enhancements.
