Hair loss due to kidney deficiency generally starts from the top of the head.

Hair loss caused by kidney deficiency, thinning, and lack of luster in the hair is a chronic symptom. There may also be other symptoms of kidney deficiency. Hair loss from kidney deficiency is more often due to yin deficiency, as the kidneys cannot directly nourish the hair.

Replenishing the kidney can promote hair growth and nourishment. Eating more green fruits, vegetables, animal liver, nuts, red beans, soy products, eggs, and dairy can help prevent hair loss.
