What is the primary function of a nail primer?

The primary function of a nail primer is to prevent lifting, which is crucial for ensuring the longevity and durability of nail enhancements. A nail primer works by creating a strong bond between the natural nail and the product being applied, such as acrylic or gel. This adhesion is essential because it reduces the likelihood of the enhancement separating from the natural nail over time, which can lead to lifting.

Lifting can occur for several reasons, including improper application techniques, moisture trapped between the nail and product, or inadequate preparation of the nail surface. By using a nail primer, technicians can ensure that the surface is properly prepared and the bond is secure, which contributes significantly to the overall success and appearance of the nail service.

The other options, while related to nail aesthetics and care, do not capture the primary purpose of a nail primer. Coloring the nails, moisturizing the cuticles, and providing shine are important aspects of nail care and enhancement, but they do not specifically address adhesion, which is the key role of a nail primer.
