South Korea, have you ever thought about dyeing beautiful hair color with traditional Chinese medicine since ancient times? Now in Beijing and Shanghai, there is such a way-dyeing hair with Chinese medicine. In fact, in Chinese medicine, there is already a method of dyeing hair with Chinese medicine. For example, it was recorded in the "Miraculous Prescription" that "sour pomegranate, gallnut and sesame leaves were grinded into coarse powder, soaked in iron storage water, and the juice was applied externally." Chinese medicine beauty salons are popular with professional Chinese medicine beauty salons, and there is also a new way of dyeing hair with Chinese medicine-using natural materials such as black sesame, watermelon peel, Polygonum Multiflori Radix, fresh eggs and honey, and then blending with vinegar and vegetable oil to make a "dye paste" according to their own hair quality and original color. The principle of this traditional Chinese medicine hair dyeing is to extract the plant pigment of Chinese herbal medicine through vinegar, and then cover the pigment on the hair through the attachment of egg white. However, this hair dyeing method is mainly based on hair care, so the color is limited, but it will be better to cover the white hair than to dye the popular color.
