Our white to black shampoo contains sodium lauryl ether sulfate and cocoamidopropyl betaine. It can reduce hair loss, enhance overall hair density, and reduce signs of hair loss, making hair appear thicker and fluffier. The method of use is very simple: first, thoroughly wet the hair with warm water, then take off the polygonum multiflorum shampoo, apply it on the scalp, rub it into rich foam, massage the hair root and scalp for 2-3 minutes, and finally rinse off the foam with water. And it can enhance the overall hair density, nourish and solidify the roots, making the hair darker and denser.
