Hello, the causes of hair loss may be stress, environmental deterioration, personal poor diet, or kidney deficiency, or harmful chemicals.

I suggest that you can drink Lycium barbarum and Rehmannia glutinosa together, three times a day. Usually drink more warm water, eat less cold drinks, don't be too tired, and combine work and rest. Eat more foods containing iron, calcium and vitamin A, such as milk, eggs, lean meat, fish, bean products and sesame seeds. The above is a suggestion on whether it is useful to soak Lycium barbarum in water for my personal hair loss. I hope it helps you, and I wish you health!
