What should you know about focal folliculitis?

A follicle can become irritated after shaving, waxing, friction, sweating, tight clothing, or an occlusive product. Bacteria or yeast may also contribute. The change is often a small red bump centred on a hair, with soreness, itch, or a tiny pustule. It can occur on the face, neck, scalp, chest, back, buttocks, or thighs.

An ingrown hair can look similar, especially after hair removal. Repeated lesions, deep tender lumps, crusting, or scalp involvement may need a closer examination to identify the trigger.

Pause shaving, waxing, and rubbing the area until it settles. Wash gently, pat dry, wear loose clothing, and avoid squeezing or scratching the bump. A warm compress may ease tenderness. Keep razors clean and do not share them; when you resume shaving, use a fresh blade and avoid repeated passes over the same skin.

A clinician may recommend topical antibiotic therapy or another treatment when infection is suspected. Oral antibiotics are not suitable for every bump, so use them only when prescribed. If the scalp is itchy or lesions recur, explain the pattern rather than repeatedly treating it as acne.

Arrange medical review if the redness expands, pain becomes marked, pus accumulates, fever develops, or the bump does not improve with gentle care. Prompt assessment is sensible for lesions near the eye, a rapidly worsening infection, or repeated episodes that leave scars or dark marks.

Ask whether the cause appears bacterial, yeast-related, shaving-related, or linked to an ingrown hair. Ask which products and hair-removal methods to pause, whether a swab is useful for recurring pus-filled bumps, and how to prevent new lesions.
