What could be a sign of a scalp infection?

Persistent itching or redness on the scalp can indicate an infection. These symptoms often arise from inflammation, which is the body’s response to pathogens such as bacteria or fungi. When the scalp is infected, the body directs immune responses to the affected area, leading to noticeable changes such as itching and redness.

Infections like folliculitis or tinea capitis, for example, may present these symptoms as they disturb the natural balance of the skin and hair follicles. In addition to discomfort, these signs can help in early identification and treatment of the infection, essential for preventing further complications.

While dry scalp, split ends, and flaky skin may indicate other issues related to scalp health or hair condition, they do not specifically suggest a scalp infection. Dry scalp usually points to a lack of moisture, split ends are related to hair damage, and flaky skin can suggest conditions like dandruff, but none of these are typically associated with infection. Thus, persistent itching or redness stands out as a key indicator of a potential scalp infection.
