Applying a barrier cream around the hairline is crucial during chemical services to prevent scalp irritation. Chemical treatments, such as hair coloring or perming solutions, can be harsh and may lead to discomfort or allergic reactions if they come into direct contact with the skin. The barrier cream acts as a protective layer, reducing the risk of irritation by creating a physical barrier between the scalp and the harsh chemicals. This practice is essential for the safety and comfort of the client, ensuring a more pleasant experience during the service.

While conditioning treatments are beneficial for the hair's health, they do not specifically protect the skin from chemical exposure. Water can dilute some products and may not provide an adequate barrier. Cleansers are used for preparing the hair or scalp but do not serve the purpose of preventing irritation. Thus, using a barrier cream is the most effective option for safeguarding the skin during chemical processes.
