It is not true that dandruff is most afraid of one herbal medicine. One herbal medicine cannot treat all diseases, and the same disease cannot be treated with one medicine. The cause of dandruff is different for each person, and you need to identify the cause of your condition before you can choose medication to treat it. In Chinese medicine, the causes of excessive dandruff include yin deficiency and blood deficiency, blood stasis and stagnation, and internalized dampness and heat. For example, dandruff caused by yin deficiency and blood deficiency needs to be treated by nourishing yin and blood (nourishing the blood in the body), and can be treated with traditional Chinese medicines such as Sizu Tang and Consistent Decoction under the guidance of a doctor. Four Substance Soup should be used with caution for people with Yin deficiency and Blood heat. Consistent Decoction should not be used for people with phlegm accumulation. If you have excessive dandruff, it is recommended that you consult a hospital and take standardized treatment under the guidance of a physician.
