Final answer:
A barrier cream or protective base is applied to a client's skin before a perm to protect it from the chemicals used in the perm solution.
Step-by-step explanation:
Before applying a chemical perm to a client's hair, it is essential to protect their skin from potential irritation caused by the chemicals used in the process. A barrier cream or protective base is commonly applied along the hairline, ears, and nape of the neck. This product serves to create a protective layer between the skin and the perm solution. Additionally, some stylists may place cotton strips or similar materials along the hairline for added protection. It is crucial to ensure that these protective measures are in place before starting the perm process to prevent any skin discomfort or adverse reactions.
