This is usually secondary to Staphylococcus aureus, which is treated with topical or oral antibiotics.Staphylococcal folliculitis is particularly prevalent in the African American human immunodeficiency virus (HIV)-positive population.The noninfectious folliculitides are induced by drugs or chemicals, or they are activated mechanically.Eosinophilic folliculitis is a rare sterile folliculitis encompassing the classic Ofuji disease, HIV-associated eosinophilic folliculitis, and eosinophilic pustular folliculitis of infancy.Certain perifolliculocentric inflammatory disorders, such as pseudofolliculitis barbae, acne keloidalis nuchae, and perifolliculitis capitis abscedens et suffodiens, although not true folliculitides, can often mimic folliculitis and are seen more often in African Americans.
