As another reviewer mentioned, I am also from CA where eyebrow threading is quite common. Finding a spot in the Murrysville/Monroeville area is a small feat just because it is not yet a "thing" out here. It will be soon, though! The owner (I did not learn her name) is fantastic. She is upbeat and friendly and was very welcoming! This spot is cash or check only.
I recommend giving threading a try next time you're thinking to get your brows waxed. In my opinion, threading allows for a more detailed and precise shape. With waxing they still have to pluck the brow hairs that are too close to your brow line. Threading solves that problem, and the best part is that it doesn't peel a layer of skin off! Great solution for people with sensitive skin who cannot tolerate waxing. Threading lasts just as long as waxing does, too.
