I know a few who have done it. Mixed reviews. Some have a great experience and swear by it, but others have come out looking misshapen or the tech didn't follow their instructions. I've never personally done it though.
My eyebrows were very thin naturally plus thyroid problems added to the problem, then hair loss during cancer treatment pretty much left me without eyebrows. I'm so glad I had it done, they look much better. I'll go back in 6 weeks for a touch-up.
It doesn't hurt. I work in a spa and everyone has this done and it looks amazing. I hate overplucked eyebrows it makes anyone look bad. I always hated that.
So, this is the answer to my prayers. I have think eyebrows but I want them fuller. So, I will save up my money and get it done. eventually. I have a house to buy first. I'll get it done by the time I'm 75.
