Folliculitis is a disease caused by an inflammatory infection, generally associated with excessive secretion from the sebaceous glands, frequent consumption of spicy and irritating foods, or staying up late. It commonly affects the scalp, face, or buttocks. For treatment, topical antibiotics can be applied, and taking oral anti-inflammatory medications may also be appropriate. If individual follicles are particularly painful and swollen, they can be disinfected and lanced with a needle to drain the pus and blood. This condition has a high recurrence rate, so after recovery, it is important to avoid spicy and irritating foods, refrain from staying up late, engage in regular exercise, avoid public baths, and minimize exposure to infectious bacteria.
