What is the function of nail primer?

The function of nail primer is primarily to ensure proper adhesion of nail products. When applied, nail primer creates a bonding surface that enhances the adherence of subsequent layers, such as base coats, nail polish, or artificial nail enhancements like acrylics or gels. This is crucial to the longevity and durability of the manicure, as it helps prevent chipping and lifting of the nail products.

Using a primer prepares the nail surface by slightly altering its texture and pH level, which in turn facilitates a stronger bond between the natural nail and the enhancements. This step is essential for achieving a professional finish and maintaining the quality of the manicure over time.

In contrast, the other options focus on different aspects of nail care. Adding shine pertains to topcoats or finishing products, strengthening nails is usually addressed through specific nail treatments or hardeners, and removing excess oils is typically done with a dehydrator or nail cleanser. Each of those serves a purpose, but none is the primary function of nail primer, which is specifically designed to optimize adhesion.
