Threading (actually called Khite)- It is popular in Arabia and middle eastern countries, as well as India. I have had this done and it is amazing. They actually use a piece of thread and pull the hair out. It is super fast, which I like. It hurts. I mean, huurrrts… But it was worth it to me. My eyebrows were perfect afterwards. PERFECT. Not a single blond stray, which is hard to do. It is the most sanitary option as well and no chemicals are used. Win-win.
