What should you know about describing folliculitis?

Folliculitis may appear as clusters of small bumps or pus-filled spots centred on hairs. It can affect the scalp, beard area, chest, back, buttocks, thighs or areas exposed to shaving, friction, sweat or tight clothing. Bacteria, yeast, irritation and ingrown hairs can all contribute, so the appearance does not identify one cause by itself.

Some cases settle when the trigger is removed, while repeated or widespread episodes may need an examination. A clinician may ask about shaving, swimming pools, hair products, medicines and whether the itchy or sore areas recur.

Wash gently, pat the skin dry and pause shaving, waxing or scrubbing over the affected area. Wear loose, breathable clothing and avoid sharing razors or towels. Do not squeeze the bumps, because this can worsen inflammation and spread infection. A clinician may recommend a topical treatment or prescribe antibiotics when a bacterial infection is diagnosed; do not use leftover medicine.

Arrange a review if bumps keep returning, spread, leave scars, cause significant pain or do not improve after removing friction and shaving triggers. Seek prompt care for rapidly worsening redness, a large tender lump, fever, extensive drainage or feeling unwell. Scalp involvement with marked hair loss also deserves assessment because other disorders can affect follicles.

Does this look like folliculitis, ingrown hairs or another skin condition? Could shaving, a product or an infection be contributing? Which cleanser or treatment should I use, and how can I prevent recurrence?
