What is an essential step before applying acrylics to a client's nails?

Proper nail preparation and cleaning is critical before applying acrylics to a client's nails. This step ensures that the natural nail surface is free from oils, dirt, and any pre-existing products. By thoroughly cleaning and preparing the nails, you create an ideal surface for the acrylic to adhere to, which enhances the longevity and overall appearance of the acrylic application.

When nails are prepared correctly, the chances of lifting or chipping are significantly reduced, leading to a more durable manicure. Preparation also typically involves removing any previous polish, pushing back or removing cuticles, and lightly buffing the nail surface. This not only promotes adhesion but also contributes to the health of the nails by preventing trapping moisture and bacteria underneath the acrylic.

The other options do not address the foundational steps necessary for a successful acrylic application. For instance, applying a nail color, using cuticle oil, or applying a thick top coat are actions that come after the acrylic has been applied, rather than being essential to the preparation phase.
