In the context of nail care, what does overfiling primarily affect?

Overfiling primarily affects the health of the nail bed. When nails are excessively filed, it can lead to thinning of the natural nail plate, making it more susceptible to damage and injury. The nail bed, which lies beneath the nail plate, can also suffer from this excessive filing, leading to discomfort or pain and potentially causing complications such as infection. Maintaining the health of the nail bed is crucial for overall nail integrity, as it supports nail growth and helps in the production of new nail cells.

The other options do relate to various aspects of nail care, but they do not capture the primary consequence of overfiling as accurately as the impact on nail bed health does. For example, while overfiling may indirectly affect the growth rate of natural nails or the adhesion of enhancements, the immediate and noticeable effect is generally on the health of the nail bed itself.
