What should you know about pseudo folliculitis?

A closely cut or curly hair can bend back into the skin as it grows. This triggers a local inflammatory response, with itchy or tender bumps, pimples or trapped hairs. The beard area is common, but the neck, scalp, legs, underarms and bikini area can also be affected. Pseudo folliculitis is different from infectious folliculitis, although scratching can break the skin and allow infection to develop. Dark marks may remain after inflammation settles, particularly after repeated episodes.

Pause close shaving while bumps are active if possible. When shaving again, soften the hair with warm water, use a clean sharp tool, shave in the direction of growth and avoid stretching the skin or making repeated passes. Do not pick, dig out hairs or squeeze pimples. A clinician may suggest a suitable cleanser, anti-inflammatory medicine, hair-removal adjustment or prescription treatment. Antibiotics are not automatically needed; topical antibiotic therapy or oral antibiotics are used only when a clinician finds a reason.

Book an appointment if bumps keep returning, leave persistent dark marks, form pus, become increasingly painful, spread, or do not improve after changing shaving habits. Seek urgent help for rapidly worsening redness, severe pain, fever or feeling very unwell. A clinician can distinguish ingrown hairs from acne, allergic irritation and folliculitis, then tailor prevention to your hair and skin.

Are these ingrown hairs or infectious folliculitis? Should I change my razor, shaving direction or hair-removal method? What can reduce inflammation and dark marks? Would prescription treatment help? Which signs mean I should return quickly?
