1, the eyebrow shape was not designed before eyebrow tattooing. In order to have a perfect effect after eyebrow tattoo, the eyebrow shape design before operation is very important. If it is not designed according to the patient's own facial condition and eyebrow characteristics, the postoperative effect will naturally be bad. Moreover, if the tattoo artist's skill is not too hard, it is easy to appear after eyebrow tattoo, such as one height and one height, one width and one narrow, one bend and one bend. 2. The technique of tattooing is not important. You want the effect after eyebrow tattoo to be natural and true. When tattooing your eyebrows, you should tattoo them in the order in which they grow. Eyebrows and eyebrows should be slightly lighter in color and thinner in density, while eyebrows should be heavier in color and denser. This is the shade in tattooed eyebrows, which makes tattooed eyebrows natural and true. 3. The color of the dye used for eyebrow tattoo is incorrect. At present, the dyes used for eyebrow tattoo are mostly dark brown, gray, black, brown and so on. The color of tattooed eyebrows should be selected according to the skin color and hair of the subjects. For example, if the hair is black and the skin is black, add one or two drops of black with natural ash. Yellow hair, white skin with natural gray and a drop or two of brown. At present, many beauticians only tattoo a single dark gray or black on their eyebrows, which will appear unreal and unnatural and look dim. 4, the use of inferior pigments Some beauty seekers choose illegal beauty salons in order to covet temporary cheapness, while beauty salons choose inferior dyes in order to reduce costs, resulting in blue eyebrows after tattoos.
