Severe hair loss caused by kidney deficiency should first be treated with medication under the guidance of a qualified physician. Generally, hair loss is mainly considered to be caused by an excess of androgens or an oversensitivity to androgens, resulting in symptoms. This condition is caused by emotional depression leading to 'fire,' so it is essential to promptly clear the meridians. For example, acupuncture can be very effective in conditioning, and eating more walnuts or black sesame in the diet can also help alleviate the symptoms of hair loss.
