Threading
We use a pure, thin, twisted cotton thread which is rolled over usually untidy hairlines, moustaches and other areas of unwanted hair, plucking the hair at the follicle level. Unlike tweezing, where single hairs are pulled out one at a time, threading can remove an entire row of hair, resulting in a straighter line. As a larger area of hair is removed at once, however, it can be relatively painful.
