What is the correct sequence for applying nail polish?

The correct sequence for applying nail polish is to start with a base coat, apply two coats of color, and then finish with a top coat. The base coat serves several important functions: it helps to protect the natural nail from staining, improves the adhesion of color polish, and can also enhance the longevity of the manicure.

Following the base coat, applying two coats of color ensures an even and opaque application, which is essential for achieving the desired color intensity and richness. The top coat is applied last; it seals the color and adds a glossy finish, enhancing the overall appearance of the nails while providing an additional layer of protection against chipping and wear.

This sequence is widely recognized in nail care practices, making it the most effective method for a flawless manicure. The other options disrupt this effective process, either by omitting necessary steps or reversing the order, which can lead to subpar results.
