What should be done to a client with visible signs of nail fungus during a service?

When a client shows visible signs of nail fungus, the best course of action is to advise them to see a healthcare professional. This approach prioritizes the client's health by ensuring that they receive proper medical advice and treatment for their condition. Nail fungus can be contagious, and continuing the nail service may worsen the condition or pose a risk to other clients.

Seeking medical attention allows the client to receive an accurate diagnosis and appropriate treatment, which may include antifungal medications or other therapeutic measures. It's essential for nail technicians to recognize their limitations in medical knowledge and to refer clients to qualified healthcare providers for any health-related concerns that go beyond the scope of cosmetology.

Continuing the service could lead to the spread of infection, while applying products to mask the fungus does not address the underlying issue and could also pose hygiene risks. Offering a discount does not resolve the health concern and may also divert attention from the client's need for medical care. Therefore, advising the client to consult a healthcare professional is the most responsible and ethical action to take.
