Barrier creams protect the client's skin before applying chemical services.

• A. During coloring
• B. After washing
• C. Before applying chemicals
• D. Only on dry skin

Answer: (C)

Barrier cream works by forming a protective layer on the skin to shield it from chemical irritation. The key is applying this protection before any chemical service begins, so the skin is safeguarded as soon as the products touch the hair or scalp. If you wait until after washing or during coloring, the chemicals may already contact the skin, increasing the chance of irritation or burns. The barrier cream is typically applied to exposed skin areas around the hairline and ears, and on the hands, prior to applying color, perms solutions, or other chemical products. It’s about timing: protect the skin first, before chemicals are introduced.
