What should you know about recurrent scalp folliculitis?

Folliculitis is inflammation around a hair follicle. On the scalp, it can look like small pimples, tender bumps, crusting, or spots that itch. A scalp rash may be worsened by friction, sweating, tight headwear, shaving, hair products, or scratching. Repeated episodes can also leave temporary dark marks or, when inflammation is deep or persistent, affect hair growth. Scalp bumps are not automatically an infection, so examination helps distinguish folliculitis from ingrown hairs, acne-like eruptions, or other causes.

Keep the scalp clean with a gentle cleanser, rinse after heavy sweating, and avoid picking or squeezing the bumps. Pause products that sting or leave a heavy residue, and wash hats, pillowcases, brushes, and clippers regularly. Do not share grooming tools. A clinician may recommend targeted topical treatment or, when appropriate, antibiotics for a skin infection; the choice depends on the appearance and cause. Take photographs when a flare is active and note recent products, hair removal, or friction.

Arrange a dermatology review when episodes keep returning, spread, form crusts, cause increasing pain, or are associated with thinning hair. Seek prompt care for rapidly worsening redness, marked swelling, fever, feeling unwell, or drainage near the eye. Urgency is based on these warning signs, not on the fact that a bump is common.

Ask whether the pattern fits folliculitis, whether a swab or other test is useful, which products should be stopped, and how long to use any prescribed treatment. Ask what changes would suggest scarring or a different diagnosis.
