What should a barber do if a client has an allergic reaction during a service?

When a client has an allergic reaction during a service, stopping the service and seeking medical assistance is crucial. Allergic reactions can vary in severity and may escalate quickly, potentially leading to serious health issues. It is important to prioritize the client's safety and well-being by assessing the situation promptly.

By stopping the service, the barber can prevent further exposure to the allergen and allow the client to receive appropriate care. Seeking medical assistance ensures that trained professionals can provide the necessary treatments, such as antihistamines or emergency interventions if needed.

Other choices, such as continuing the service, using cold water, or applying topical medication, may not adequately address the potentially serious nature of an allergic reaction and could further complicate the client's condition. By following the correct procedure of halting the service and getting medical help, the barber acts responsibly and professionally, ensuring the client's health is the top priority.
