Before performing chemical services, it is crucial to check the client’s medical history. This step is essential because certain medical conditions, medications, or allergies can impact how a client’s hair and scalp will respond to chemical treatments. For instance, clients undergoing specific medical treatments may have compromised skin integrity or sensitivity that could lead to adverse reactions during chemical processes such as coloring, perming, or relaxing.

Understanding a client’s medical history helps ensure their safety and the effectiveness of the service. If a client has a history of allergic reactions to chemicals, skin disorders, or any relevant medical treatments, this information allows the barber or stylist to take necessary precautions, such as performing patch tests or modifying the service.

While checking hair texture, fashion preferences, and age can inform the stylist's approach to the chemical service, they do not carry the same level of health-related risk as the client’s medical status.
