I just got back from trying Perfect Brows after noticing their recent opening and how they already seemed like they were busy with customers. For a first timer, I must say it really was a great experience! I keep looking at myself in the mirror now, noticing what a difference a little bit makes. I don't have any other threading experience to compare it to, so I don't know if it's supposed to be more painful, but I guess I'm lucky. It's a little prickly, but definitely not painful.
And not only are they reasonably priced, but it saves so much time from standing in front of the mirror, stabbing away at your eyebrows with tweezers.
