Abstract: A hair cutting guide, for use by a hairdresser in cutting the hair of a person using scissors, having a pair of guide halves that are hingeably attached and selectively enter an open position and a closed position. Each of the guide halves have a plurality of teeth arranged along its longitudinal edges. The teeth have an inner surface that face the inner surfaces of the teeth in the other guide halve when the guide is in the closed position. Combs extend perpendicularly to the inner surfaces such that hair is extended transversely between the longitudinal edges and is held in place by the combs when the guide is closed. Straight cutting and point cutting is carried out by cutting with the scissors adjacent to the teeth along one of the longitudinal edges when the guide is in the closed position.
