What does the term "lifting" refer to in the context of nail enhancements?

Lifting in the context of nail enhancements refers to the situation when artificial products, such as acrylics or gels, begin to pull away from the natural nail plate. This occurrence can happen due to several factors, including improper application, insufficient preparation of the natural nail, exposure to moisture, or wear and tear over time. It is essential for nail technicians to understand lifting as it can impact the overall appearance of the nail enhancement and result in potential infection or damage to the natural nail.

In contrast, the other choices refer to different aspects of nail care but do not capture the specific issue of lifting. For instance, techniques for applying polish, filing nails, or removing old enhancements address different processes within nail service rather than the consequence of a product not adhering properly. Understanding lifting is crucial for ensuring the longevity of nail enhancements and maintaining the health of the nail bed.
