What should you know about black folliculitis?

A clinician can distinguish infection from irritation, acne-like conditions, and hairs curling back into the skin. That distinction matters because treatment differs.

Folliculitis causes small inflamed bumps centred on hair follicles. They may itch, feel tender, contain pus, or crust. On brown or black skin, redness can look purple, deep brown, grey, or less obvious than expected.

A dark mark can remain after the inflammation settles; this is post-inflammatory hyperpigmentation rather than ongoing infection. Shaving, friction, sweating, occlusive products, and ingrown hairs can trigger or worsen follicle irritation.

Pause close shaving, waxing, and plucking over the area. Wash gently, reduce rubbing from tight clothing or headwear, and use a clean warm compress for discomfort. Do not squeeze, scratch, or dig for a trapped hair because this can deepen inflammation and leave more discoloration or scarring.

Avoid sharing razors and replace blades that drag across the skin. If bumps keep returning, a dermatologist may examine the pattern, take a swab when infection is suspected, and choose an antimicrobial or another treatment suited to the cause. Antibiotics are not appropriate for every follicular bump.

Arrange prompt medical assessment if redness or dark discoloration is rapidly expanding, pain is worsening, the skin feels hot and swollen, drainage is increasing, or you develop fever or feel unwell. A large tender lump can represent a deeper infection that should not be squeezed.

Book a routine dermatology visit when bumps recur in the same area, cause thick or raised scars, lead to patchy hair loss, or fail to improve after removing likely triggers. Seek earlier advice if medicines or a health condition weaken your immune system.

Ask whether the bumps are caused by infection, ingrown hairs, product irritation, or another skin condition; whether a swab is useful; how to change hair-removal methods; and which products can treat lingering pigment without irritating active bumps. Mention any tendency to form raised scars.
