What is the function of a nail brush?

The function of a nail brush is primarily to remove debris from the nail and surrounding skin. This is an important step in maintaining proper hygiene and cleanliness in nail care. When performing manicures or pedicures, using a nail brush helps to eliminate dirt, dead skin cells, and any other foreign particles that may cling to the nails and the skin around them.

A clean nail surface is essential for the application of nail products, as it ensures better adhesion and a more professional finish. In addition, removing debris can prevent infections and promote healthier nails and skin. Thus, the nail brush serves as a vital tool in both aesthetic and health aspects of nail care, establishing a foundation for any further procedures such as polishing or applying products.

The other options refer to different functions that do not align with the primary use of a nail brush, focusing instead on tasks that are typically performed with other tools or techniques during a manicure or pedicure.
