We have all done this, and honestly it gets rather annoying. The cost is the lowest (which is just the price of a pair of tweezers), but it is extremely time-consuming and can be rather painful, especially if you have never done it before. Tweezing takes patience, attention to detail, and some drawing skills. Usually, before you start,you have to first draw the shape you want for your eyebrows with a makeup pencil. From there, you pluck all the unwanted hairs around the drawn line. Now, if you're not symmetrical in your drawing, you will end up with quite odd-looking eyebrows because they won't be even. There will be times, even for some of the best professional tweezers, when they miss the hair and catch the skin instead. This can be rather painful and you may even break the skin.
