Mupirocin for scalp folliculitis: what to know

Scalp folliculitis is inflammation around hair follicles. It may cause small red or pus-filled spots, tenderness, itching, or crusting. Friction, sweating, hair products, shaving, ingrown hairs, bacteria, yeast, and other skin conditions can produce similar findings. Mupirocin is a topical antibiotic for certain bacteria, so a clinician may need to inspect the scalp before recommending it. Related symptoms include [Itchy Scalp](/symptoms/itchy-scalp/), [Skin Bumps](/symptoms/skin-bumps/), and [Pimples](/symptoms/pimples/).

If prescribed, apply mupirocin to the affected skin as directed, avoiding the eyes and washing hands before and after application. Do not spread it across the entire scalp unless told to do so, and do not use a leftover tube for a new outbreak. Keep combs, hats, and pillowcases clean; avoid picking, tight headwear, and products that sting. A clinician can explain [Topical Antibiotic Therapy](/treatments/medical-dermatology/topical-antibiotic-therapy/) and broader [Antibiotics For Skin Infection](/treatments/medical-dermatology/antibiotic-therapy-for-skin-infection/).

Arrange prompt review if pain, warmth, swelling, pus, or redness is spreading, or if fever develops. Seek assessment for hair loss, deep lumps, extensive crusting, or repeated flare-ups. Urgent help is appropriate for rapidly worsening illness or swelling near the eye. If symptoms persist, the clinician may check for an ingrown hair, yeast-related condition, or another scalp disorder.

Ask whether the bumps are bacterial folliculitis, an ingrown-hair problem, or another condition; where to apply the medicine; and how long to use it. Ask which shampoo or styling changes may reduce irritation and when to return if the scalp does not settle.
