Folliculitis is divided into infectious folliculitis as well as non-infectious folliculitis, mild folliculitis can usually heal itself in 5-7 days. Infectious folliculitis includes fungal folliculitis, bacterial folliculitis, etc. Non-infectious folliculitis includes eosinophilic folliculitis, medicated folliculitis, etc. Clinical bacterial folliculitis is the most common. For mild bacterial folliculitis, after the bacteria invade the body, the body’s natural immune system will automatically recognize and release chemokines as well as inflammatory factors, etc., to participate in the clearance of the pathogen. When the pathogen is cleared, the activated cells begin to apoptosis under the body’s own metabolism and the inflammatory response subsides, at which point mild bacterial folliculitis heals itself, a process that takes about 5-7 days. For some severe bacterial folliculitis, it is clinically recommended to actively treat it with sensitive antibiotic drugs to avoid further aggravation and the possibility of bacteremia. For other types of folliculitis, appropriate treatment should be given according to the specific cause.
