Infected hair follicles and folliculitis

The problem usually begins in the follicle, the small skin opening from which a hair grows, rather than in the visible hair shaft. Friction, shaving, sweating, occlusive clothing, or contaminated water can contribute, while bacteria, yeast, and other causes require different management.

Folliculitis may present as a cluster of red or skin-coloured bumps, white-tipped spots, tenderness, itching, or crusting. A hair may be visible in the centre. It can occur anywhere hair grows, including the scalp, beard area, trunk, buttocks, arms, or legs.

An ingrown hair can also inflame a follicle after shaving or hair removal, but not every follicular bump is infected. Acne, boils, contact reactions, and heat-related irritation may resemble folliculitis. Examination is especially useful when the eruption keeps returning or does not respond to basic care.

Avoid squeezing or picking because this can deepen inflammation and spread material to nearby follicles. Pause shaving over the area, reduce friction, wear loose breathable clothing, wash gently, and use a clean warm compress for comfort. Do not share razors or towels.

Discard or clean the tool that may have triggered the eruption according to its care instructions. Prescription treatment depends on the suspected cause and extent; antibiotics do not treat yeast-related or purely irritant folliculitis. A clinician may take a swab from drainage if the cause is unclear, severe, or recurrent.

Book an appointment if bumps are widespread, worsening, repeatedly returning, leaving scars, or failing to settle with gentle care. A deep, very painful lump may be a boil or abscess and can require drainage rather than home treatment.

Seek prompt medical care if redness or swelling spreads quickly, red streaks develop, pain becomes severe, fever occurs, or you feel unwell. Earlier assessment is also sensible when the area is close to the eye or when medicines or illness weaken immune defences.

Tell the clinician where the bumps started, whether shaving, a hot tub, sweating, or a new product preceded them, and whether anyone close to you has similar lesions. Ask whether testing is useful, which hygiene steps matter, when hair removal can resume, and how to prevent recurrence.
