Alopecia areata is characterized by patchy hair loss on the scalp, with most symptoms being mild. This is especially true for some children, who do not require special treatment after onset. Adjusting their diet or lifestyle, avoiding picky or unbalanced eating, and consuming more vegetables and fruits can lead to self-healing. However, if the area of alopecia areata is large or the symptoms are progressively worsening, with increasing patchy hair loss, formal treatment is then necessary. It can be helpful to check for trace elements to see if there are any deficiencies, or to visit the dermatology department of a formal hospital for a hair follicle test to check for any atrophy or necrosis. Subsequently, formal medication can be used for treatment, which can completely cure the condition ultimately. It is important to maintain a regular diet and lifestyle habits, avoid staying up late, anxiety, and stress, strengthen exercises, and enhance immunity, all of which can aid in treatment.
