The head is the part of the body where the sebaceous glands of hair follicles secrete the most. In adolescent men and women, due to the enhanced secretion of sex hormones, the secretion of sebaceous glands further increases and excessive secretion of oil may occur, blocking hair follicles and pores, causing folliculitis or sebaceous gland inflammation and cysts to occur. At this time, due to the stimulation of inflammatory symptoms, it may cause local pain, redness and swelling, even accompanied by local fever and other symptoms. If folliculitis occurs, it is recommended to strengthen the local skin care of the head, in addition to going to the hospital for treatment by a doctor. In addition to oral anti-inflammatory drugs, you should also pay attention to the usual light diet, normal rest and activities.
