Threading is a technique of removing hair practiced since time immemorial in the Middle East, South Asia and South-East Asia and now becoming popular in the West. Threading involves twisting a thread of pure cotton between the fingers and around rows of hair to pull them out at their roots. It is commonly used for shaping eyebrows and removing other facial and body hair. Threading rarely causes harm to the skin and suits even people with sensitive skin. It is therefore, especially good for facial hair removal, where the skin is particularly sensitive.
