What should be done if a client experiences an allergic reaction during a treatment?

When a client experiences an allergic reaction during a treatment, it is essential to prioritize their health and safety. Rinsing the affected area is a critical step because it helps remove any product that may be causing the reaction, potentially alleviating symptoms and preventing further irritation. Notifying the client about the situation is also important, as it keeps them informed and allows them to understand the necessary actions being taken to ensure their well-being.

Waiting to see if symptoms improve could lead to a more severe reaction, and continuing the treatment as planned disregards the client’s health, which contradicts professional standards of care in cosmetology. Additionally, charging the client for a treatment during an adverse reaction is inappropriate and can damage the client-provider relationship, as it may be perceived as prioritizing profit over client safety. Therefore, effectively managing allergic reactions involves immediate action to minimize discomfort and ensure the client's safety.
