Alopecia areata is commonly treated by applying raw ginger topically, which has a certain effect. Rubbing ginger juice on the affected scalp area can stimulate hair follicles and improve local blood circulation, offering some therapeutic benefits for alopecia areata. However, this is generally only used for mild symptoms or cases that have just developed. If the alopecia areata has been present for a long time or if long-term medication has been ineffective, the application of ginger tends to be minimally effective. If the symptoms are severe, it is advisable to seek formal treatment at a dermatology department of a regular hospital. Adjusting one's diet and lifestyle habits is important; avoid spicy and irritating foods, and do not consume overly salty or highly flavored foods. Strengthening exercise, avoiding staying up late, and preventing anxiety and stress are also recommended.
