What is the primary purpose of nail preparation before applying polish?

The primary purpose of nail preparation before applying polish is to ensure better adhesion and longevity of the manicure. Proper preparation involves cleaning the nails, removing oils and debris, and sometimes gently buffing the surface to create a smooth texture. This allows the polish to grip the nail effectively, reducing the chance of chipping, peeling, or lifting. A well-prepared nail surface promotes a longer-lasting finish, which is crucial for client satisfaction and the overall success of the nail service.

While enhancing the color of the polish, changing the shape of the nail, and creating a decorative effect are important aspects of nail care and artistry, they do not primarily address the fundamental need for polish adhesion and durability, which is critical for a professional finish.
