How do you thread your own eyebrows?
Threading works by using cotton thread that is twisted and rolled along the surface of the skin. Entwining the hair in the thread and lifting it out of the follicle. The skin usually reacts with a little redness and slight soreness, however, it is considered an effective hair removal for people unable to tolerate waxing.
Although threading has become increasingly popular as an option to other methods, threading does require special training. In answer to your question, please don't try this at home, check with a licensed Esthetician. :-)
You can't. Its impossible! You and a friend can go watch and do each others!
