A hair follicle can cause folliculitis, or a boil. It is mainly caused by bacterial infection. Before clinical treatment, routine blood tests can be performed to see if the total white blood cell count is elevated, and if it is elevated it confirms this diagnosis. In clinical treatment, you need to choose a treatment plan according to your condition. If the hair cyst is more obvious and densely distributed, you need to immediately administer levofloxacin hydrochloride injection or cefoxitin sodium injection to strengthen the antibacterial and anti-infective effect, and you need to apply topical Revnor solution twice a day for 20 minutes. After the dressing, apply fusidic acid ointment, or mupirocin ointment twice a day. During the treatment period, you need to avoid eating a spicy, irritating diet and alcohol.
