  • Patent number: 4387729
    Abstract: This invention pertains to a new concept in hair drying. To achieve this concept requires the use of modified rollers and a drying unit which is also modified to represent an improvement over conventional drying methods. Plastic tubing from the drying unit is inserted and enclosed inside perforated rollers which have been used to roll wet strands of hair. When the unit is in operation, hot air can only escape through the perforation of the roller which is covered with wet hair. Since the air stream is directed away from the scalp, there is less chance of burning the scalp. The heat also penetrates a larger volume of hair which decreases drying time.
