Folliculitis is actually a bacterial infection of the hair follicle area, and if local breakdown has occurred, alcohol or iodophor can be applied to disinfect the area. If the skin is not obviously broken, rubbing with alcohol will not eliminate the inflammation deep in the hair follicle. In this case, the patient can apply antibiotic ointment for external application, such as Bactrim ointment, erythromycin ointment, fusidic acid ointment, and metronidazole ointment. But some patients with serious local folliculitis and multiple, the application of topical antibiotic ointment may not be very effective, can be combined with oral or intravenous application of antibiotic drugs. If the folliculitis is very serious and has become pus localized, it is best to perform puncture drainage, and after the puncture drainage, alcohol or iodophor can be applied for local disinfection.
