People with kidney deficiency type hair loss can drink milk because milk also helps with calcium supplementation, which can effectively increase the body's resistance and enhance some bodily functions. However, it is necessary to consume it in moderation, as excessive intake could lead to digestive issues in the gastrointestinal tract. Therefore, careful attention is required. Additionally, in daily meals, it's advisable to eat more foods that help nourish the kidney, such as goji berries and donkey-hide gelatin, which can effectively replenish kidney deficiency and lead to improvements. It is crucial to also focus on strengthening physical exercises regularly.
