Redness and irritation are key indicators of a scalp infection. These symptoms suggest inflammation, which typically occurs when the scalp is under attack from bacteria, fungi, or other pathogens. When an infection is present, the immune system responds, leading to increased blood flow to the affected area, which can result in redness. Additionally, irritation may manifest as discomfort, itching, or a burning sensation, all of which are associated with infections.

In contrast, flakiness, dandruff, and excessive oiliness are symptoms that may be related to other scalp conditions but do not specifically indicate an infection. Flakiness can result from dry skin, while dandruff is often linked to a yeast-like fungus but not necessarily a full-blown infection. Excessive oiliness might indicate a scalp that produces too much sebum but again does not imply an underlying infection. Therefore, the presence of redness and irritation is a strong indicator that a scalp infection may be present.
