However, this degree of nature is not to dye hair, but to look more shiny. The first person to dye his hair should be Wang Mang, the new emperor. As we all know, Wang Mang usurped the Han Dynasty and proclaimed himself emperor. He was 60 years old when he became emperor, and his hair was even gray, which was very old in ancient times. In order to stabilize the situation of the new dynasty and make himself look younger, Wang Mang came up with a way to dye his hair.
It is said that Wang Mang's hair cream is made of soybeans, that is, black beans are soaked in vinegar, and the residue is filtered, and the remaining juice is boiled into a paste. Although this kind of hair dye is easy to use, its effect is naturally not as long-lasting as that of modern hair dye, and it needs to be dyed frequently to keep the color.
Generally, except black beans, anything with pigment can be made into hair cream, such as hibiscus leaf juice, rice juice, saponin and so on. In the Tang Dynasty, when the society was open, dyeing hair became a trend, but turning hair white did not weaken people's pursuit of beauty with age. However, the hair dyes of the ancients were all natural and did no harm to the body. Now many hair dyes contain heavy metal salts, which are harmful to the body, so the hair color is moderate.
