Folliculitis is the medical term for inflammation of a hair follicle. It typically presents as pink bumps or pustules (pus filled bumps) centered around a hair follicle. The condition can appear anywhere on the body where there are hairs, including on the face, chest, back, buttocks, and/or legs. The condition can be caused by infections (commonly bacteria or yeast), irritation, occlusion/blockage, or medications. Common treatment options include topical and/or oral antibiotics or antifungals.
