What is one common sign of scalp infection?

1. Inflammation or redness on the scalp

2. Excessive hair loss

3. Dryness of the scalp

4. Overproduction of oil

The correct answer is: Inflammation or redness on the scalp

Inflammation or redness on the scalp is a common sign of a scalp infection because it indicates an inflammatory response. When an infection occurs, the body's immune system reacts to the invading pathogens, leading to increased blood flow to the area. This can result in visible changes such as redness, warmth, and swelling as immune cells work to combat the infection. Recognizing these signs is crucial for timely intervention and treatment, as untreated scalp infections can lead to more severe conditions. Excessive hair loss can occur due to various reasons, including infections, but is not solely indicative of a scalp infection. Dryness of the scalp and overproduction of oil can also result from other conditions or environmental factors, rather than directly signaling an infection. Focusing on inflammation or redness specifically highlights the body's immediate response to infection, making it the most accurate choice in this context.
