What is the function of a dehydrant in nail services?

A dehydrant is specifically designed to reduce moisture on the nail plate, which is crucial in preparing the nails for various services, particularly for enhancements like acrylics or gels. When moisture is present on the nail surface, it can lead to problems such as peeling, lifting, and improper adhesion of products.

By effectively minimizing the moisture content, a dehydrant ensures that the nail surface is clean and ready for the application of nail products, promoting better adhesion and longevity of the enhancements. This step is essential for achieving optimal results in nail services, making the use of a dehydrant a vital component of the nail preparation process.

The other functions mentioned in the question are not the primary purpose of a dehydrant; nourishing the nails or promoting nail growth are related to other products like oils and treatments, while enhancing color retention typically involves the use of specific color products or sealants rather than moisture removal.
