Folliculitis is a bacterial infection of the hair follicles and surrounding tissues. Most cases of folliculitis are caused by Staphylococcus aureus, with occasional infections from epidermal staphylococci, Streptococci, E. coli, and others either alone or in combination. Another scenario involves fungal folliculitis secondary to bacterial infection, typically involving Malassezia, spores, and Dermatophytes. Contributing factors include high temperatures, excessive sweating, scratching, poor hygiene habits, certain chronic systemic diseases, and long-term use of corticosteroids. Therefore, the treatment of folliculitis requires understanding the specific cause of the infection, followed by targeted treatment of the cause. Initial measures should focus on maintaining skin cleanliness and hygiene, preventing injuries, and boosting the body's immune system, primarily using topical medications. For widespread folliculitis or severe secondary infections, systemic medication may be required. If there is a concurrent fungal infection, antifungal medications are also necessary. In severe cases of folliculitis, where there is abscess formation and pus accumulation, timely incision and drainage are needed, and one should avoid squeezing the affected areas.
