Is white hair on the head kidney yin deficiency or yang deficiency

White hair on the head may be caused by kidney yin deficiency or kidney yang deficiency.

After kidney yin deficiency occurs, due to lack of yin fluid in the body, it will cause hair to be discolored, causing white hair on the head. After kidney yang deficiency occurs, it can lead to weakness in the circulation of qi and blood in the body, unable to rise to clear orifices, and hair does not get sufficient qi and blood supply, which will also cause white hair on the head. However, other factors can also cause white hair on the head, such as long-term mental stress, malnutrition, drug effects, etc. Therefore, it is not possible to judge whether kidney yin deficiency or kidney yang deficiency according to the white hair on the top of the head. It is suggested that the patient go to the hospital for examination and definite diagnosis.
