Contagious folliculitis: what to know

Folliculitis means inflammation centred on a hair follicle. Friction, shaving, ingrown hairs, blocked follicles, medicines, bacteria, or yeast can contribute. A bacterial or fungal cause may pass through contaminated personal items or close contact, but irritation after shaving does not behave like a contagious infection. Small red or skin-coloured bumps, pus-filled spots, tenderness, itch, or crusting may occur. [Folliculitis](/conditions/folliculitis/) gives the wider condition overview.

The appearance alone cannot establish whether germs are present. A clinician may consider the distribution, recent hair removal, water exposure, household symptoms, and whether spots are worsening.

Do not squeeze or scratch the bumps. Avoid sharing towels, razors, clothing, bedding, or personal grooming tools, and wash reusable items regularly. Pause shaving or waxing over active spots; if shaving resumes, use a clean razor and avoid close passes. Keep the area clean and dry without harsh scrubbing. Treatment depends on the cause and may include [Topical Antibiotic Therapy](/treatments/medical-dermatology/topical-antibiotic-therapy/) or [Antibiotics For Skin Infection](/treatments/medical-dermatology/antibiotic-therapy-for-skin-infection/), but these should be selected by a clinician.

Book an assessment when bumps keep returning, spread beyond shaved areas, form painful clusters, drain pus, or affect the scalp, beard, or groin. Seek prompt help for fever, rapidly increasing pain, expanding warmth, red streaks, or feeling unwell. People with reduced immunity or poorly controlled diabetes should seek advice earlier for suspected skin infection.

Ask whether the pattern suggests bacteria, yeast, irritation, or ingrown hairs; whether a swab is needed; how long to avoid shaving or shared items; and when it is reasonable to return to close-contact activities. Mention recent pools, hot tubs, grooming, medicines, and similar symptoms in household members.
