Fo-Ti, or polygonum multiflorum, is known in China from the legend of “Old black-haired Mr. He.” The story goes that Old Mr. He was too weak and sickly to leave town to find food when famine struck. Instead, he stayed and lived off the roots of the fo-ti plant he dug up. When the famine passed and the villagers returned, they discovered a bright-eyed, black-haired, and energetic Mr. He. From then on, fo-ti has been used in TCM to combat many age-related issues, but especially for graying or dull hair. Regular use of this shampoo may help restore color and vitality to your hair.
