What should be done before conducting a chemical service on a client?

Before conducting a chemical service on a client, it is essential to conduct a patch test. This procedure is crucial because it helps to determine if the client has any allergies or sensitivities to the chemicals that will be used during the service. A patch test is typically performed by applying a small amount of the chemical product on a discreet area of the client’s skin and observing for any adverse reactions, such as redness, swelling, or itching, over a specified period.

Ensuring the client does not have an adverse reaction to the products is vital for their safety and the success of the chemical service. This precaution helps to prevent serious skin reactions that could lead to discomfort or injury during or after the treatment.

Other considerations, like evaluating a client's mood, discussing pricing, or scheduling follow-up appointments, are important aspects of client interaction but do not directly address the safety and suitability of the chemical service being provided. Conducting a patch test remains the most critical step prior to any chemical treatment.
