Abstract
Abstract An attachment for a hair dryer performs the function of providing a lower velocity diffused air flow with apparatus to separate and lift the hair and allow the entire hair strand, from root to end, to be dried at the same time. The attachment includes a base member shaped to expand and turn a column of air from a conventional blow dryer by, for instance, 45 degrees. A face plate holds a diffuser pad in position. Extending from the face plate away from the base are a plurality of hair lifters, each of which lift a small amount of hair, so as to permit the entire hair, from root to end, to receive air and be dried at the same time. The face plate includes a plurality of holes therethrough to permit air flow and each hair lifter includes a post extending upward from the edge of the hole and an extension from the top of the post into the area above the corresponding hole. This structure allows the face plate to be fabricated by injection molding. Techniques to even the air flow through the holes of the face plate are also described. In use, the attachment is inserted into the hair, rotated to allow the lifters to separate and catch the hair and then removed to lift the hair while drying. While removing the attachment, it may be redirected towards or away from the face or it may be moved outward along a spiral path.
