What should be done if a client has an allergic reaction to a product?

When a client experiences an allergic reaction to a product during a service, it is crucial to prioritize their health and safety. Stopping the service immediately allows the stylist to assess the situation without further exposure to the allergen, which could exacerbate the reaction. If the symptoms are severe or show no signs of improvement, seeking appropriate medical attention is a necessary step to ensure the client's well-being.

Monitoring the situation closely can be important, but only after the service has been halted and the client's needs addressed. Cold compresses can provide relief, but they should only be used as an additional measure after stopping the service. Recommending over-the-counter medication without professional guidance could be inappropriate, especially considering the client's unique health needs and conditions. Thus, prioritizing immediate cessation of the service and assessment aligns best with safety protocols in a salon environment.
