What should you know about folliculitis scalp?

Spots can appear along the hairline, under dense hair, or where helmets, hats, and close haircuts create heat and friction. Sweat, oily products, scratching, and shaving can irritate follicles. Some people notice crusting or tenderness when a pustule breaks. Itchy scalp has many possible causes, including dermatitis and infection, so itch alone does not identify folliculitis. Repeated inflammation can leave dark marks, scarring, or areas where hair grows less well.

Wash after heavy sweating and rinse shampoo thoroughly. Avoid scratching, tight headwear, greasy styling products, and close clipping until the skin improves. Use your own combs, towels, hats, and pillowcases, and wash items that touch the affected area. Do not pick crusts or bumps. A clinician may recommend a medicated wash, topical therapy, or antibiotics after checking whether the cause is bacterial, fungal, or irritant.

Book an assessment if scalp bumps persist, recur, become painful, ooze, or cause crusting and hair loss. Seek prompt care for fever, rapidly spreading redness, marked swelling, or severe pain. Early review matters when scarring or thinning appears because ongoing follicle inflammation can affect hair growth.

Ask whether the scalp needs a swab or another test, which shampoo or treatment is appropriate, and when you can resume shaving or styling. Tell the clinician about new products, hats, helmets, haircuts, sweating, and any areas of thinning.
