I've been doing my eyebrows now for the past 8 years. I touch them up every one to two years. I rotate between powdered and hair strokes, because I like them both. I go to two ladies one for each look. They follow the original shape that I got 8 years ago. I love them!
When getting them make sure you have a trust worthy, licensed, esthentician and tattoo artist. One that you can go to over and over again.
My skin is semi-oil so I always like to go in for touch ups because I like my brows dark. After you tattoo them they peel and become lighter and lighter over time.
