I've been coming here since I moved to Vegas 3 years ago, and never looked back with my newly perfectly threaded eyebrows.
The stylists here can be kinda hit or miss, but there are a couple that are on point every time. If you don't want to take the chance, go see Sasha. Call ahead if you can. She is not only an amazing stylist, but also an amazing person. I don't know what she does differently in her technique, but it hurts less than some of the other stylists. Sasha will give you an amazing threading experience and sage wisdom from her life experience. I always love talking to her.
The reception staff here is forever changing, and the girl that was at the reception desk last night was very very friendly. Another perk is that they do customer loyalty points! You get a free threading for every 10 visits (I'm not completely sure on the number but I got a free one last night!).
Threading is far better than waxing. If you haven't tried it before, I would urge you to go here first.
