The causes of alopecia areata are complex and mostly related to individual factors, so ordinary hair washing generally does not exacerbate the condition. The main factors are still linked to a decrease in personal immunity, genetic inheritance, lack of vitamins and trace elements in the body, or long-term consumption of spicy and stimulating foods, frequent staying up late, anxiety, tension, and poor mood. However, frequent hair dyeing or perming, and the use of hair products with strong irritants such as hair gels and conditioners, may aggravate the symptoms of alopecia areata. Once this disease occurs, it is essential to seek treatment at accredited medical institutions. With long-term persistence, it is entirely possible to cure the disease completely.
