When a client experiences an allergic reaction during a service, the recommended action is to notify a supervisor immediately. This step is crucial as it ensures that the situation is handled professionally and appropriately.

Allergic reactions can vary in severity, and while some may be mild, others can escalate quickly into more serious conditions that require medical attention. By notifying a supervisor, you ensure that the client receives the appropriate care and that the situation is handled with the proper protocols set by the establishment. The supervisor can assess the situation and determine the best course of action, which may include administering first aid, contacting medical personnel if necessary, or assisting the client in getting the help they need.

In contrast, applying cold water to the area, continuing the service, or applying over-the-counter cream may not be sufficient or appropriate responses without proper training in handling allergic reactions. Each of these actions could potentially worsen the situation or delay necessary treatment. Therefore, promptly alerting a supervisor is the most responsible and safe response.
