Before performing a chemical service on a client, conducting a thorough consultation and performing a patch test are critical steps. The consultation allows the cosmetologist to gather important information about the client's hair type, history of chemical treatments, allergies, and overall health. This information helps in determining the appropriate chemical products to use and ensures that the service aligns with the client's expectations.

The patch test is essential in identifying any allergic reactions the client may have to the chemicals being used. By applying a small amount of the product on a discreet area of the skin, you can monitor for any adverse reactions before applying the product to the hair. This precautionary measure is vital for the safety and well-being of the client, as it can prevent potential allergic reactions that could lead to discomfort, skin irritation, or other health issues.

While applying a conditioning treatment, washing the client's hair, or providing a relaxation treatment may be beneficial steps in a broader service, they do not address the immediate safety and suitability concerns associated with chemical applications. Therefore, the combination of a thorough consultation and a patch test is paramount to ensuring a successful and safe chemical service.
