The purpose of a base coat in nail services is to protect the natural nail and improve polish adherence. A base coat forms a barrier between the natural nail and the nail polish, which can prevent staining and damage to the nail surface. Additionally, it creates a slightly textured surface that helps the polish adhere better, resulting in a more durable and long-lasting manicure. By using a base coat, the overall appearance and integrity of the nails are enhanced, making it an essential step in the nail care process. This protective layer significantly contributes to the health of the nails while ensuring that the color polish applies smoothly and evenly.
