The factors like bacteria, fungus, regular hot tubs, and shaving of hair increase the risk for folliculitis. It is found that foods rich in fats or a high-fat diet exacerbate neutrophilic folliculitis. It causes acne, hidradenitis suppurativa (painful lumps under the skin), and elevated bumps on the skin. The avoidance of fat-rich foods may improve the symptoms. The folliculitis also responds well to antibiotic and antifungal treatment but may recur.
