The pigments used in the eyebrows are dark brown, gray, black, brown, etc., and should be selected according to the color of the hair and skin. The color of oriental hair is often mixed in several colors, a little dark gray, and a little dark brown. Therefore, the color of the eyebrow liquid should be suitable for people. The hair is black, the skin is darker, and the natural gray is added with one or two drops of black; the hair is yellowish and the skin is white with natural gray plus one or two drops of brown. In the experiment, many beauticians only use a single dark gray or black to tattoo, so that the eyebrows will be unreal and unnatural, and the eyebrows will appear dull and distorted.
