What should be done prior to performing a chemical service on a client?

Conducting a client consultation is essential prior to performing a chemical service on a client because it allows the cosmetologist to gather vital information about the client’s hair type, previous chemical services, allergies, and overall desires regarding the treatment. This thorough understanding helps in determining the appropriate chemical products to use, as well as assessing any potential risks associated with the service. During the consultation, the cosmetologist can also discuss the expected results, maintenance, and aftercare, ensuring that the client’s expectations align with what can realistically be achieved.

In contrast, while assessing the client's preference, performing a hair color test, or applying a patch test are important steps, they come after the initial consultation. The consultation provides the groundwork upon which these other procedures may be based, ensuring that all decisions are tailored to the client's specific needs and circumstances.
