What is one of the signs of an infection that barbers should watch for?

One of the primary signs of infection that barbers should be vigilant about is redness and swelling around the shaved area. This response indicates that there may be an inflammatory process occurring in response to either a microbial invasion or irritation caused by shaving. When the skin becomes infected, the body sends immune cells to the affected area, which can cause both redness and swelling as a result of increased blood flow and the accumulation of white blood cells.

Identifying these indicators early allows barbers to take appropriate action, such as referring the client to a medical professional or advising against further shaving in the area until it heals. Addressing infections promptly is crucial to prevent further complications and to ensure the safety and health of clients.
