What should a technician do if a client shows signs of an allergic reaction during a nail service?

When a client exhibits signs of an allergic reaction during a nail service, the immediate and most critical action is to stop the service and remove the product. This step is essential to prevent further irritation or potential harm to the client. Allergic reactions can escalate quickly, and continuing the service could exacerbate the situation, leading to more severe reactions. Removing the product promptly helps minimize discomfort and mitigates the reaction's severity.

It's also crucial for the technician to ensure the client's safety by providing appropriate first aid or notifying medical personnel if the reaction is severe. Stopping the service and taking immediate action reflects the technician's responsibility for the client's well-being and adherence to safety protocols in the salon environment.
