What should you know about occlusion folliculitis?

When clothing, equipment, dressings, oils, or prolonged pressure hold heat and moisture against the skin, follicles can become irritated or blocked. Small red bumps, pimples, or pustules may appear where the covering touches, and the area may itch, sting, or feel sore. Ingrown Hairs, shaving, and bacterial or yeast overgrowth can create a similar picture, so persistent or widespread symptoms may need an examination rather than self-diagnosis.

Remove or loosen the suspected covering when safe, change out of damp clothing, shower after heavy sweating, and pat skin dry. Choose breathable fabrics and avoid oily products or repeated rubbing on the area. Do not scratch or squeeze the bumps, and pause shaving over active lesions. A clinician may recommend an antiseptic, topical medicine, or treatment for the specific cause. Topical Antibiotic Therapy or Antibiotics For Skin Infection are not interchangeable with general skincare and should be used only when prescribed or advised.

Arrange a medical review if bumps keep returning after the trigger is removed, spread beyond the covered area, become painful, drain pus, form deep nodules, or leave scars. Seek urgent care for rapidly spreading redness, severe pain, fever, or feeling very unwell. Scalp symptoms with marked itching, crusting, or hair loss also deserve assessment because other conditions can resemble folliculitis.

Ask whether the rash is folliculitis, acne, heat rash, or an ingrown-hair problem; which trigger to avoid; whether a swab is needed; and how long to use any prescribed treatment.
