Alopecia areata, commonly known as "ghost shaving," is a type of immune-related skin disease. It is important to rest, provide immune modulation and other symptomatic treatments, eat more black-colored foods, and maintain a good mood. Take oral thymopeptide enteric capsules, cysteine tablets, vitamin B6 tablets, folic acid tablets, and other medications. For the bald areas, apply a 5% concentration of minoxidil spray and heparin polysulfate mucopolysaccharide cream. The purpose is to improve scalp microcirculation to stimulate hair follicles and promote hair regeneration. Simultaneously, supplementary physical therapy measures can be used, including traditional Chinese medicine techniques such as plum-blossom needle tapping and local treatment with 308 nm excimer laser radiation, three times a week, for a total of ten sessions per treatment course.
