Using barrier creams is essential during hair coloring services because they create a protective layer on the skin that helps prevent staining and irritation from the dye. These creams typically contain ingredients that can repel water and substances, acting as a shield between the hair color chemicals and the skin.

Barrier creams are specifically formulated for this purpose and are designed to withstand the harsh chemicals often found in hair dyes. They not only protect the skin from potential allergic reactions or rashes but also minimize color transfer, ensuring that the client's skin remains clean and unaffected by the treatment.

While hydrating lotions, moisturizing gels, and hair oils offer benefits for skin and hair health, they do not provide the same level of protection against staining and irritation as barrier creams do. Hydrating lotions and gels are more focused on moisture retention, and hair oils are used primarily for conditioning and shine, making them unsuitable for protecting the skin during hair coloring.
