Learning to tattoo eyebrows depends on whether there is a foundation. With the foundation, you can learn advanced tattoo skills in a few days. Without foundation, it takes a certain amount of time to learn introductory skills, and it takes a long time to learn fine tattoos. It is easy to learn some skills and techniques, but it takes a lot of time to learn the essence. You should practice more, sum up more and accumulate experience slowly, so practice makes perfect.
