Eyebrow tattooing is to beautify the eyebrow shape by coloring the eyebrows with colored milk, which will slowly absorb and fade, so it usually lasts for two years.
Some irregular beauty salons tattoo eyebrows with cheap colored milk, which may lead to unnatural eyebrow color diffusion and great harm to the body.
General hair transplant hospitals can also tattoo eyebrows, which have technical advantages in design and operation and are more formal in materials.
