What are common signs of an infected cut in a barbershop setting?

Swelling, redness, and pus discharge are classic signs of an infection. In a barbershop setting, these symptoms indicate that the body's immune response is reacting to the presence of pathogens at the site of an injury or break in the skin, such as cuts or nicks that can occur from shaving or haircutting. The swelling is a result of increased blood flow to the area, while redness is a visible response indicating inflammation. Pus discharge suggests that the body is trying to fight off the infection, containing dead white blood cells, bacteria, and tissue debris.

Other options present signs or conditions that do not specifically relate to infections. Dryness and cracking may relate more to skin conditions or environmental factors, while bleeding and scabbing normally occur during the healing process. Itching and flaking might indicate allergic reactions or other skin irritations but are not directly indicative of an infection. Hence, the combination of swelling, redness, and pus provides a clear indication of an infected cut, making it the correct choice.
