Using a nail dehydrator primarily serves the purpose of removing moisture and oils from the surface of the nail plate. By eliminating these elements, which can hinder the adhesion of nail products like polish or acrylic, the dehydrator helps ensure that the products applied afterward adhere more effectively. This step is crucial for achieving a longer-lasting finish and minimizing issues such as lifting or chipping of enhancements.

Although some might consider other functions like enhancing color or adding shine, those are not the main objectives of a nail dehydrator. It is specifically designed to create an optimal surface for product application, ensuring that the nail service is durable and maintains its integrity over time.
