What is the purpose of using a base coat in nail services?

1. To enhance nail design

2. To protect the natural nail and enhance polish adhesion

3. To add color to the nails

4. To provide a glossy finish

The correct answer is: To protect the natural nail and enhance polish adhesion

A base coat serves a vital role in nail services by primarily protecting the natural nail and improving the adhesion of nail polish. It creates a smooth, often slightly tacky surface for the subsequent layers of polish to adhere to more effectively. This means that the polish is less likely to chip or peel, extending the wear time of the manicure. Additionally, a base coat can help prevent staining of the natural nail from colored polishes, particularly darker shades, which can sometimes leave discoloration if applied directly. By creating this protective barrier, the beauty and health of the natural nail are maintained. The other options address different aspects of nail care or design: enhancing nail design focuses on the visual aspects of manicure aesthetics, adding color specifically refers to the application of polish or designs, and providing a glossy finish pertains to top coats rather than base coats. While these elements are important, they do not encompass the protective and adhesion-enhancing functions that base coats offer.
