What should be done if a customer has an adverse reaction during a service?

When a customer experiences an adverse reaction during a service, stopping the service and providing appropriate first aid is the most responsible and ethical course of action. This ensures the immediate safety and well-being of the client. An adverse reaction could range from a mild skin irritation to a more severe allergic reaction, which might require urgent attention.

Taking the necessary steps to address the issue not only shows professionalism and care but also helps to prevent any potential complications that could arise from continuing the service. This approach demonstrates a commitment to the health and safety of clients, which is paramount in the beauty industry.

Continuing the service could worsen the reaction, putting the client at further risk, while seeking a second opinion from another barber may not lead to a quick or effective resolution. Similarly, ignoring the reaction entirely is unprofessional and could have serious consequences for the client. Thus, providing first aid and stopping the service is the correct and most prudent decision in such a scenario.
