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

  1. Add shine

  2. Prevent staining

  3. Enhance color

  4. Protect the nail bed

The correct answer is: Prevent staining

The purpose of a base coat in nail care primarily revolves around preventing staining of the natural nail. When colored nail polish is applied directly to the nails, especially those that contain strong pigments, it can cause discoloration. A base coat acts as a protective layer that creates a barrier between the nail and the colored polish, significantly reducing the risk of staining. This is particularly important for clients who frequently use darker shades, as continuous exposure can lead to permanent discoloration. While a base coat can also contribute to enhancing the adherence of nail polish and prolonging its wear, its primary function is to safeguard the integrity of the natural nail from potential damage caused by pigmentation in the polish. This protective measure helps maintain the overall health and appearance of the nails.
