Threading: Threading is an ancient technique of removing hair. Threading is very popular in India and the Middle East, and now is growing in the West. Practitioners use a thin, twisted cotton thread which is rolled over usually untidy hairline, mustaches, 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 from the root, resulting in a straighter line. No chemical is involved in threading, so your sensitive skin will be more protected, and unlike waxing, it does not peel the top layer of skin. Threading shapes your eyebrows the way you want.
