Gray Hair

In Traditional Chinese Medicine (TCM), the occurrence of graying hair is often attributed to a specific disharmony pattern known as Kidney Essence Deficiency, frequently accompanied by symptoms such as dizziness, blurred vision, and hair loss (Hsu et al., 2013, Journal of Traditional and Complementary Medicine). This deficiency principally affects Kidney Yin but may also implicate Kidney Yang, impacting a broad range of physiological processes, including growth, development, and the health of bone, marrow, teeth, and hair. A deficit in Kidney Essence is theorized to cause premature hair graying and loss (Chen & Xu, 2015, Evidence-Based Complementary and Alternative Medicine). In TCM parlance, "essence" is considered the foundational substance governing the immaterial aspects, akin to the soul and an individual's physical constitution.
