What condition may prevent a barber from providing services?

The presence of active scalp infections or contagious skin conditions is a condition that may prevent a barber from providing services due to health and safety regulations. These infections can easily be transmitted to others, posing a risk to clients and colleagues in the barbershop environment. Public health standards dictate that barbers must ensure a safe and sanitary space for all clients, and working with an active infection can compromise that safety.

In contrast, dry scalp or minor cuts on hands are generally manageable and do not pose a significant risk of spreading infection to clients. Excessive hair loss, while it can be a concern for clients seeking hair styling or treatments, does not impact the barber's ability to perform their duties or the health safety of the services offered.
