If a cosmetologist observes an allergic reaction during a service, the most appropriate action is to stop the service and provide care. Allergic reactions can vary in severity, and it is essential to prioritize the safety and well-being of the client. By stopping the service, the cosmetologist can prevent further exposure to the allergen and avoid exacerbating the reaction.

Providing care may involve assessing the reaction, calming the client, and determining if any immediate medical intervention is required. This may include applying an appropriate topical treatment or even calling for medical assistance if the reaction seems serious. Quick and decisive action not only helps in managing the situation but also demonstrates professionalism and concern for the client's health.

Continuing the service while informing the client later can be dangerous, as it might lead to a worsening reaction unnecessarily. Similarly, changing products immediately could still pose a risk, especially if the new product contains similar allergens. Consulting with a colleague might be helpful in some circumstances, but the immediate priority should always be the client's safety through cessation of the service and provision of care.
