A sign of a scalp infection is indicated by the presence of redness, swelling, and pus-filled bumps. These symptoms typically suggest an inflammatory response that occurs when the scalp becomes infected, often due to bacteria or fungi. The redness indicates increased blood flow to the area as the body attempts to fight off the infection, while swelling is a result of fluid accumulation and inflammation. Pus-filled bumps are indicative of the body’s immune response, where white blood cells congregate to combat the invading pathogens, leading to the formation of abscesses or pustules.

Other symptoms, such as dry flaky skin or itching without visible symptoms, may occur in various scalp conditions but do not specifically point to an infection. Hair loss in patches can also result from several factors, including infections, but the combination of redness, swelling, and pus-filled bumps specifically characterizes an active infection, making it a clear sign of this condition.
