What is the effect of using a dehydrator on the nail?

Using a dehydrator on the nail effectively removes excess oil and moisture from the nail surface. This process is crucial, especially before applying nail enhancements like acrylics or gels, as it ensures better adhesion. When the nail is dehydrated, it creates a cleaner, drier surface that allows products to bond more effectively. This reduces the risk of lifting and improves the longevity of the nail design.

The other effects highlighted in the answer choices focus on different aspects of nail preparation. For instance, increasing moisture retention or promoting shine are contrary outcomes to what a dehydrator aims to achieve. Similarly, softening the nail plate may lead to weaker nails, which is not the desired result when preparing the nail for enhancements. Therefore, the primary purpose of using a dehydrator is to eliminate unwanted moisture and oils, thus ensuring a strong foundation for any subsequent nail application.
