Why is it important to apply a barrier cream before coloring hair?

Applying a barrier cream before coloring hair is important primarily to protect the client's skin from staining. Hair color contains strong pigments and chemicals that can cause unwanted discoloration on the skin, which is often difficult to remove. By using a barrier cream, you create a protective layer that minimizes the risk of the dye transferring onto the skin, ensuring a cleaner application process. This not only enhances the client’s comfort during the coloring procedure but also contributes to a more professional outcome by preventing unsightly stains around the hairline and on the ears.

While vibrancy, moisture, and color longevity are important considerations in the hair coloring process, they are not directly addressed by the application of barrier cream, making skin protection the primary purpose of this practice.
