What type of product is commonly used to protect the skin during hair color application?

The use of a barrier cream during hair color application is essential for protecting the skin. Barrier creams are specifically designed to form a protective layer on the skin, preventing the hair color from directly contacting the skin and reducing the risk of irritation, allergic reactions, or staining. These creams are formulated to be water-resistant and create an effective barrier, making them particularly useful in salon practices.

While moisturizers are intended to hydrate the skin, they do not offer the same level of protection against chemical products. Sunscreen is important for protecting the skin from UV radiation but is not relevant in the context of hair color application, as it does not provide a barrier to the dyes. Toners, on the other hand, are used in hair coloring processes to adjust color tone but have no protective function for the skin. Thus, barrier cream is the appropriate product for safeguarding the skin during hair color treatments.
