What should barbers always use after cleaning a wound?

Barbers should always apply a bandage after cleaning a wound to protect it from further injury and contamination. Using a bandage helps create a barrier against dirt and bacteria, which is crucial in promoting proper healing and reducing the risk of infection.

While applying a topical antiseptic is a common practice to disinfect the wound initially, it is the bandage that actually covers and safeguards the area. Sterile gauze can be used as part of the process to absorb any fluid and protect the wound as well, but it often requires a bandage for secure placement. Hydrogen peroxide, while it is an antiseptic, can be too harsh on skin and might impede healing.

In a barbering context, after cleaning a wound, the immediate priority is to ensure it is covered and protected, making the application of a bandage the most appropriate and effective choice.
