What condition is indicated by hair falling out or being dull with a tendency to split?

The condition indicated by hair falling out or being dull with a tendency to split is primarily associated with Liver Blood deficiency. In Traditional Chinese Medicine, the liver plays a crucial role in the nourishment and maintenance of hair health. Blood is considered essential for providing the necessary nutrients to the hair follicles and promoting healthy hair growth. When there is a deficiency of liver blood, the hair may become weak, fail to thrive, and exhibit characteristics such as dullness and splitting.

Liver Blood deficiency can also lead to other symptoms, such as pale complexion, dizziness, and poor memory, due to the overall lack of nourishment that blood provides to the body. This aligns with the understanding of how vital liver blood is for maintaining robust hair.

While other conditions, like Kidney deficiency, Spleen Qi deficiency, and Excess Liver Heat, can cause hair issues, they typically manifest with additional symptoms or have different characteristics in relation to hair health. Consequently, the specific link between hair weakness and dullness is most directly and accurately associated with Liver Blood deficiency in this context.
