Stopping the service immediately and providing assistance is crucial if a client exhibits signs of an allergic reaction during a service. This action prioritizes the client's health and safety, as allergic reactions can escalate quickly and become severe, potentially leading to more serious health issues. By ceasing the service, the cosmetologist can prevent further exposure to the allergen and initiate necessary responses, such as administering first aid or contacting emergency services if needed.

In contrast, continuing the service or applying more product could worsen the reaction, as exposure to the irritant may aggravate symptoms. Simply informing the client to seek medical attention later does not address the immediate needs of the client and may delay important care in a critical moment. Therefore, the most responsible and protective step is to stop the service and attend to the client’s condition right away.
