I had my eyebrows tattooed about 12 years ago and I absolutely love them. I had one touch up six weeks after the first application and the brows are still the same color and shape.
I think it is very important to communicate with the technician that is going to implant the tattoo. The technician that did mine did an excellent job and explained the procedure and the do's and don'ts.
Having my eyebrows done has saved me so much time and I am very happy that I chose to have it done.
