Before performing a chemical service on a client, conducting a consultation and patch test is essential. This step ensures the safety and suitability of the chemical treatment for the client's hair type and skin sensitivity. The consultation allows the cosmetologist to understand the client's hair history, preferences, and any specific concerns they may have. It also provides an opportunity to discuss potential outcomes and ensure that both the cosmetologist and client are on the same page regarding the service.

The patch test, which involves applying a small amount of the chemical product to a discreet area of the client’s skin, is crucial for identifying any allergic reactions or sensitivities that could lead to adverse effects during or after the chemical application. If a client reacts negatively to the patch test, it may indicate a need to select a different product or approach for their specific hair and scalp condition.

While consultations about hairstyles and previous chemical treatments are important for providing personalized service, they do not address the immediate safety concerns regarding the client's health. Providing a list of service options is less targeted and does not encompass the necessary health and safety evaluations that a patch test provides. Thus, the combination of a thorough consultation and a patch test is the most critical step before any chemical service.
