What is the recommended action if a client has a scalp infection?

The recommended action when a client has a scalp infection is to refer them to a physician. This is crucial because a scalp infection may require medical diagnosis and treatment that goes beyond the scope of cosmetology services. Continued hair or scalp treatments could exacerbate the infection, potentially causing further harm to the client and posing a risk of transmission to others.

Consulting a physician ensures that the client receives appropriate medical care, such as prescription medication or a specific treatment plan tailored to their condition. Referral to a healthcare professional also protects the integrity of the cosmetologist's practice by adhering to health and safety regulations surrounding infections.

While options like applying a medicated shampoo or using a chlorine rinse may seem beneficial, they may not effectively treat the underlying issue or could lead to complications. Therefore, proper referral is the most responsible and professional course of action in such situations.
