eyebrows color this means that by combining these pigments we want to make our color as similar to the natural hair or eyebrows pigment of our model as possible the most important thing and the most important factor for the final look of the color is the thickness of the epidermis or the depth into which the pigment is applied will represent the different depths with the skin samples of different thickness with shallow work or thin skin that covers the pigment. As you all already know pigments can be classified into synthetic and iron oxide pigments.
first difference between iron oxide and synthetic pigments is different stability of these colors this means that after a while some colors disappear faster while some are more stable and are retained for a longer period of time. A negative feature of iron oxide pigments is that they are magnetized when it counts.
synthetic pigments black has its positive and negative roles a negative role is that the eyebrows for example their color cannot look warm from the beginning however a positive role of stable black is that the eyebrows won’t become reddish after a year. A another positive side of synthetic pigments is the absence of heavy metals and the fact that they’re not magnetized what also makes a big difference between these two pigments is their specific weight.
