When should artificial enhancements generally be removed?

Artificial enhancements should generally be removed when the natural nail grows out significantly because this is crucial for maintaining the health of both the artificial enhancement and the natural nail. As the natural nail grows, the gap between the enhancement and the cuticle may create a space where bacteria can enter, potentially leading to infection or other issues. Furthermore, significant nail growth can also cause the enhancement to not fit properly, leading to lifting and chipping.

Regular maintenance is important to ensure that enhancements continue to look good and function properly as the natural nail grows. Typically, after a certain amount of time, the enhancement can become a source of stress for the natural nail if it's not adjusted or removed, which sustains both aesthetic and health considerations.

The other options may lead to premature removal or to neglecting the natural nail's health. For instance, removing enhancements simply because they begin to chip does not take into account the overall integrity and health of the natural nail; waiting for the client's personal choice may not coincide with the nail's health needs; and insisting on a specific weekly timeframe like every two weeks does not consider the unique growth rate of each individual's natural nails.
