The AirTouch technique is unique in that it uses air, versus traditional teasing and backcombing, to achieve a seamless blend of color. To attain this result, hair is parted into sections and highlighted in foils or clear film, as opposed to the freehand techniques that are used when creating balayage or ombre hair. The sections of the hair are then worked on in a more diagonal fashion, rather than the usual linear highlights that have been popular for the past few years.
