Is hair loss related to kidney deficiency?

Generally, hair loss is associated with kidney deficiency in some cases, but not all hair loss is caused by kidney deficiency. A comprehensive evaluation based on overall symptoms is necessary for accurate diagnosis. If concerned, it is advisable to consult a healthcare professional early. Detailed analysis is as follows:

In traditional Chinese medicine (TCM), the kidneys govern hair, and sufficient kidney essence nourishes the hair, supporting its growth and health. When kidney deficiency occurs, insufficient essence may lead to inadequate nourishment of the hair, potentially causing hair loss. This type of hair loss is often accompanied by symptoms such as soreness and weakness in the lower back and knees, dizziness, tinnitus, insomnia, frequent dreams, and premature graying of hair. Hair loss of this nature is directly related to kidney deficiency and should be treated primarily by tonifying the kidneys and enriching essence.

However, the causes of hair loss are complex. Besides kidney deficiency, other factors such as insufficient qi and blood, liver qi stagnation, internal damp-heat, or acquired factors like high stress levels, poor diet, and irregular lifestyle may also contribute. Some individuals experiencing hair loss do not show obvious signs of kidney deficiency and may only present with hair thinning, oily scalp, or itching. In these cases, the connection to kidney deficiency is minimal, and blindly supplementing the kidneys may fail to improve symptoms or even worsen them.

When hair loss occurs, avoid self-diagnosing it as kidney deficiency and taking tonics indiscriminately. Maintain a regular sleep schedule and avoid staying up late, eat a balanced diet rich in nutrients, reduce mental stress, and avoid excessive pulling or tension on the hair.
