In what order should you apply polish to a client's nails?

The correct sequence for applying nail polish is to first use a base coat, followed by enamel, and then finish with a top coat.

The base coat serves multiple purposes: it creates a smooth surface for the enamel, helps the color adhere better, and provides a protective layer that can prevent staining of the natural nail. After the base coat, enamel is applied to add color and create the desired aesthetic look. Finally, applying a top coat seals the color and provides a durable, glossy finish, enhancing the longevity of the manicure while adding protection against chipping and wear. This systematic approach ensures a professional-looking result and maintains the health of the nails underneath.
