What should a cosmetologist do if a client shows signs of an allergic reaction?

When a client shows signs of an allergic reaction, it is crucial for the cosmetologist to respond quickly and effectively. Stopping the treatment immediately is essential because continuing could exacerbate the reaction or cause further discomfort to the client. Providing first aid is also vital, as it helps to manage immediate symptoms and ensures the client feels safe and cared for.

This approach aligns with safety protocols in the cosmetology field, where the health and wellbeing of clients are the top priority. Recognizing allergic reactions promptly allows for a swift response, which can prevent complications. Waiting to apply soothing lotions or consulting with a physician without addressing the immediate symptoms could lead to worsening conditions or a negative experience for the client. Thus, stopping the treatment and administering first aid is the most responsible and effective course of action.
