Using barrier cream during hair coloring serves the important function of creating a protective barrier on the client’s skin. This cream is applied to areas such as the hairline and ears to safeguard the skin from potential staining and irritation caused by the chemicals in hair color formulations. Because hair coloring products often contain harsh chemicals, the barrier cream helps to prevent discoloration of the skin and minimizes the risk of allergic reactions or irritation that can occur with direct contact.

While strengthening the hair shaft and enhancing color vibrancy are significant concerns in the hair coloring process, they are not functions served by barrier cream. Additionally, adding moisture to the hair focuses on conditioning rather than protecting the skin during the application process. Thus, protecting the client’s skin from stains and irritation is the primary and correct purpose of using barrier cream during hair coloring.
