Which product is used to protect the scalp during a relaxer application?

The base cream is specifically designed to protect the scalp and skin during a relaxer application. This type of cream acts as a barrier that helps prevent irritation and chemical burns from the strong chemicals found in relaxers. The application of base cream prior to the relaxer process is crucial as it allows the stylist to safeguard sensitive areas of the scalp while ensuring that the relaxer can effectively do its job on the hair without affecting the scalp's integrity.

In contrast, conditioner, moisturizer, and hair oil serve different functions. Conditioners are typically used post-service to hydrate and restore moisture to the hair. Moisturizers are intended to hydrate the hair and scalp but do not provide the chemical barrier necessary for relaxers. Hair oil can be used for various purposes, such as adding shine or nourishment, but is not formulated to protect the scalp during a chemical application like a relaxer. This highlights the specialized role of base cream in a safe and effective relaxer procedure.
