In most hospitals in China, alopecia areata is a dermatology department. Patients with alopecia areata see a doctor. It is generally necessary to diagnose alopecia areata as true or false, or alopecia caused by alopecia or other diseases, such as lichen planus and discoid lupus erythematosus. At this time, besides clinical observation, dermatoscope can also be used to rule out alopecia areata caused by most other diseases. After diagnosis, dermatology generally uses topical drugs to treat alopecia areata, such as glucocorticoid and minoxidil tincture, or local subcutaneous injection of glucocorticoid, or more serious alopecia areata, which can be treated with oral drugs. In addition, many dermatologists also carry out traditional Chinese medicine treatments such as red light and plum blossom needle.

There may still be many people who believe in Chinese medicine. Alopecia areata can also be treated with traditional Chinese medicine, and some people also have good results. If alopecia areata is serious and the condition is stable, if hair transplantation is considered, plastic surgery departments in some hospitals can do it, so alopecia areata is mostly treated by dermatology.
