What is a common sign of a scalp infection?

1. Itchiness only

2. Dryness and flaking

3. Redness and swelling

4. Excessive oiliness

The correct answer is: Redness and swelling

A common sign of a scalp infection is redness and swelling. When the scalp is infected, it typically reacts with inflammation, leading to these visual indicators. The presence of redness indicates that the body is responding to a potential irritant or pathogen, while swelling suggests an accumulation of fluid as part of the inflammatory response. This reaction can be due to various causes, such as bacterial or fungal infections, and is often accompanied by other symptoms like pain or tenderness in the affected area. In contrast, itchiness may occur with a variety of scalp conditions but isn't definitive for an infection. Dryness and flaking can be signs of conditions like dandruff or seborrheic dermatitis rather than an infection, and excessive oiliness is often more related to issues like seborrhea rather than infection. Recognizing redness and swelling as key indicators helps in diagnosing scalp infections effectively.
