What is the primary purpose of a nail primer?

The primary purpose of a nail primer is to enhance the adhesion of nail products to the natural nail. This is crucial in both artificial nail applications and enhancements, like acrylics or gel nails, as it creates a bond that ensures the longevity and durability of the manicure. A good primer helps to remove oils and moisture from the nail surface, which could otherwise affect how well the products adhere, leading to peeling or lifting. Unlike the other options, which address different aspects of nail care, the function of a primer is specifically focused on improving the adherence of subsequent layers, making it an essential step in achieving a professional and long-lasting nail service.
