Question: 1 / 400

When should a nail technician apply a base coat?

After applying nail polish

Before applying nail polish to prevent staining

Applying a base coat before applying nail polish is essential for several reasons. Primarily, a base coat serves to create a barrier between the natural nail and the colored polish. This barrier helps to prevent staining, which can occur when certain pigments in nail polishes penetrate the keratin of the nail plate, leading to discoloration.

Additionally, the base coat can enhance the adhesion of the colored polish, leading to a more even application and potentially extending the wear time of the manicure. It can also improve the overall appearance of the finished look by providing a smooth surface for the polish to adhere to. Thus, ensuring that a base coat is applied before the nail polish is critical for both nail health and aesthetic outcomes.
