Twirling hair is the processing of rotate or briskly revolving strands around an object, usually a finger or set of fingers. Hair can be twirled while dry or wet. For some people with natural curls, coils or kinks, twirling the hair while wet or damp is a method of setting the texture into a desired shape. It also means to twist or wind around. Some people will twirl one or more strands of hair around their finger as a nervous habit.
