Can folliculitis cause lumps on the scalp?

Folliculitis of the scalp often presents with lumps. Folliculitis is usually caused by bacterial infection, which may result from inadequate scalp hygiene or scratches from fingernails during washing, allowing bacteria to proliferate and cause inflammation of the hair follicles. When the inflammation worsens, lumps may form, accompanied by symptoms such as redness, swelling, and pain. In addition, long-term use of estrogen medications, diabetes, and other factors may lead to decreased immunity, increasing the risk of folliculitis and associated lumps. Therefore, when lumps caused by folliculitis appear on the scalp, prompt medical attention should be sought, treatment should be followed as directed by a physician, and proper scalp hygiene should be maintained to prevent worsening or recurrence of symptoms.
