Folliculitis is a type of inflammatory infectious disease that is not contagious, meaning it does not spread through contact between individuals. This condition is mainly associated with excessive sebum secretion, consumption of spicy and irritating foods, and frequent sleep deprivation leading to bacterial infections on the skin surface. Once it occurs, commonly used oral and topical anti-inflammatory medications can completely cure it. After recovery, it is important to avoid spicy and irritating foods for a long period, try not to stay up late, avoid bathing in public baths or swimming in public pools, not keep small animals at home, and possibly take some medication to reduce sebum secretion. If individual folliculitis does not subside over time, it can be disinfected with iodophor, then punctured with a needle to clean out the pus and blood.
