Hair loss can be caused by many reasons. This condition falls under the category of dermatology and can be fully treated in the dermatology department of regular hospitals. The main causes of this disease are often related to a lack of vitamins and trace elements. Some patients suffer from anemia, or frequently experience anxiety, stress, and poor mood leading to hormonal imbalances. Once this disease occurs, it is crucial to identify the causes and treat them accordingly. Generally, it is recommended to consume more vegetables and fruits, avoid spicy and irritating foods, and reduce salt intake. Engaging in regular exercise to boost the immune system, using a massage stick to tap the scalp to promote local blood circulation can also be beneficial for hair growth. It is advisable to avoid staying up late, feeling anxious or stressed to prevent hormonal imbalances.
