Alopecia areata is not hereditary; it is mostly caused by personal factors, such as irregular and unbalanced diets, or consuming spicy and overly salty foods. Additionally, frequent anxiety, tension, and bad moods can also lead to the condition. Generally, by regulating one's diet and lifestyle habits, milder cases can improve without medication. However, if the symptoms of alopecia areata worsen and the area of hair loss expands, formal medication is needed. With long-term persistence, complete recovery is possible. During treatment, it is important to regulate diet and lifestyle habits, strengthen exercise, and enhance immunity, all of which aid in treatment.
