I suggest you consult a Chinese medicine health care doctor. I am a related health care doctor who consulted. I eat walnuts, pine nuts and jujubes quantitatively before dinner every day, soak them in water with Panax notoginseng in the morning or grind different kinds of soybean meal juice in the morning. As long as I take this eating habit as a habit, my hair will be dark and thick, with many unexpected effects.
