These two methods are best for small areas on the face. With tweezing, each individual hair is plucked at the root with tweezers and eventually grows back in with a softer, tapered end. Threading involves a long piece of thin cotton thread that is twisted and then repeatedly run along an area. Because it pulls out a line of hairs at a time, it results in a more precise shape (with eyebrows, for example), but can be a bit painful for some people. Both tweezing and threading are great alternatives for those who get skin irritations from waxing.
