What is required of cosmetologists when performing hair color services?

When performing hair color services, it is essential for cosmetologists to follow safety procedures and conduct a test for allergic reactions. This practice is critical for ensuring the safety and well-being of clients, as some individuals may have sensitivities or allergies to certain ingredients commonly found in hair color products. Performing an allergic reaction test before applying the dye allows the cosmetologist to identify any potential adverse reactions, which can prevent discomfort or severe allergic responses during or after the service.

While informing clients about potential side effects and using products that may be natural or made in a specific location can be important considerations, they do not compare to the immediate duty to ensure the client's safety through proper testing and adherence to safe practices. Moreover, regulations typically emphasize the necessity of pre-service safety measures, making it a foundational component of responsible cosmetology.
