What should the practitioner do if a client starts having an allergic reaction during a service?

If a client starts experiencing an allergic reaction during a service, the appropriate response is to discontinue using the product immediately. This is crucial to prevent further irritation or complications. Allergic reactions can escalate quickly and lead to more severe health issues, so stopping the product allows for the potential resolution of symptoms and minimizes the risk of exacerbating the reaction.

Continuing with the service could lead to more serious reactions, and applying a topical anesthetic could further irritate the skin or mask symptoms that need to be addressed. Also, asking the client to fill out another consultation form is not practical in an emergency situation since it does not address the immediate health concern and can delay necessary action. Thus, discontinuing the use of the product is the safest and most responsible course of action.
