Applying ginger to the localized skin of alopecia areata can stimulate hair follicle growth and improve local blood circulation, which has a certain effect in treating alopecia areata. However, it is generally only limited to patients with relatively mild symptoms, smaller areas of hair loss, or a shorter duration of the condition. If the duration of the actual alopecia areata is long, or the patch area is large, it is advisable to seek formal treatment at a regular medical institution. This condition also relates to personal diet and lifestyle habits. It's important to exercise regularly, strengthen immunity, avoid eating spicy and stimulating foods, and refrain from frequently perming or dyeing hair, or using aggressive styling products like hair gels or creams. Generally, as long as treatment is adhered to, it is possible to be completely cured.
