What is the benefit of using a top coat in nail application?

Using a top coat in nail application is beneficial primarily because it provides a glossy finish and protects the underlying polish. The glossy finish not only enhances the appearance of the nails, making them look polished and professional, but it also creates a layer of protection over the colored polish. This protective layer helps to prevent chipping, scratches, and wear, extending the life of the manicure.

Additionally, the top coat seals the color underneath, ensuring that the hue remains vibrant and intact for a longer period. It is an essential step in the nail application process for achieving durability and giving nails that high-shine look that many clients desire. This understanding is crucial for anyone studying for the cosmetology exam, as the use of top coats is a fundamental practice in nail care and aesthetics.
