The causes of alopecia areata are quite complex, mostly related to an individual's diet or lifestyle habits, such as long-term consumption of spicy and stimulating foods, or overly flavored foods. Additionally, some people have long-term poor nutrition, unhealthy eating habits, irregular meal times, and lifestyle habits such as frequent staying up late, feeling anxious, stressed, or being in a bad mood; all these are triggering factors. For a general examination, one can first go to the hospital to check for trace elements to see what is lacking. A complete blood count could also be performed to check for symptoms of anemia, or one could visit the dermatology department of a regular hospital to test the hair follicles and see if there is any local follicle necrosis. This disease can be completely cured by seeking treatment in the dermatology department of a regular hospital, using oral and topical medications, provided the treatment is adhered to.
