I'm very particular about my brows as I am a firm believer that they frame one's face and can dramatically change how one looks. I can't recommend Ria Beauty Parlour enough. Check this place out if you want perfect arches!
Ria is nothing less than amazing! I had my eyebrows threaded, I couldn't of asked for better results!. She listened to all my requests and gave great recommendations for future visits. My thin eyebrows ended up looking so much fuller and I don't even have to fill them in with pencil anymore.
