Which nail product helps to prevent staining from colored polishes?

• A. Base coat
• B. Top coat
• C. Nail hardener
• D. Cuticle oil

Answer: (A)

The product that helps to prevent staining from colored polishes is a base coat. A base coat is designed to create a protective layer over the natural nail, which not only helps in providing an even surface for color application but also acts as a barrier between the nail and the pigments found in colored polishes. This barrier minimizes the risk of staining, particularly with darker or more vibrant colors that tend to leave pigments behind on the nail surface.

In addition to preventing staining, a base coat can also enhance the adhesion of the polish, contribute to a smoother finish, and help the polish last longer. This protective function is crucial for maintaining the health and appearance of the natural nails, especially for those who frequently use colored nail products.
