What should be done if a client has an allergic reaction during a service?

If a client exhibits an allergic reaction during a service, applying a cold compress and advising them to see a doctor is the most appropriate course of action. An allergic reaction can vary in severity, and it is essential to prioritize the client’s health and wellbeing. The application of a cold compress can help soothe irritation and reduce swelling, providing immediate relief from discomfort.

Additionally, advising the client to seek medical attention ensures that any potential complications are managed by a healthcare professional who can assess the reaction's severity and provide appropriate treatment. This response reflects a responsible and ethical approach to client care in the cosmetology field, emphasizing safety and well-being over the continuation of a service.
