  • Patent number: 4471791
    Abstract: Method and apparatus for shaping human hair to provide a particular hairstyling effect wherein hair which has been moistened is shaped by moving a cutting blade through the moist hair to razor cut and/or thin or blunt the hair. The blade is manipulated such that the hair is trained into a predetermined set position while the same is being cut and/or thinned. Simultaneously, a stream of hot or cold air is directed across the blade generally in the direction of movement of the blade. The air stream moves out ahead of the cutting blade after sweeping the same to thereby help train the hair into the aforementioned set position while at least semi-drying the moisture from the hair, whereby upon completion of the conjoint razor cutting and blowing, the hair is shaped into final placement for the desired hairstyle.
