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

A base coat serves several important functions in nail services, with one of its primary purposes being to protect the natural nail from staining. When applying colored nail polish, certain pigments can seep into the nail bed and cause discoloration or staining, especially with darker shades. The base coat acts as a barrier, preventing these pigments from penetrating the nail and helping to maintain the natural nail's health and appearance.

In addition to preventing staining, the base coat also helps in creating a smooth surface for the application of colored polish, enhancing the overall look of the manicure. However, its primary function remains the protection of the natural nail, ensuring that clients can enjoy their nail color without compromising the integrity of their nails underneath.
