DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
This invention relates to treating hair and in particular to a method of waving of hair and a device for carrying out the method.
In known methods of waving or imparting a curl to hair, the hair is rolled onto a roller and subjected to heat and/or to a hair treatment chemical which has the effect of retaining the waving or curling in the hair for a period of time.
SUMMARY OF THE INVENTION
According to one aspect of the invention a device for use in imparting a wave to a tress of hair comprises a tube open at, at least, one end to receive a tress of hair extending lengthwise of the tube; said tube being formed of an elastic material such as to permit said tube to be stretched lengthwise by manually applied force and to return to an unstretched state when the manual force is removed; and first and second gripping means located at locations spaced apart along the tube for securing the tube at said spaced locations to the tress of hair.
According to another aspect of the invention a method of treating hair includes the steps of inserting a tress of hair into a tube of resiliently extendible material; securing the tube at a first lengthwise location thereof to the tress of hair; extending said tube lengthwise; while said tube is so extended, securing the tube at a second location thereof spaced lengthwise of the first location to the tress of hair; permitting the tube to return to an unextended state to thereby cause the hair contained in the tube to assume a waved form; and subjecting the hair contained within the tube to a chemical hair treatment substance effective to retain the hair substantially in said waved form.
BRIEF DESCRIPTION DRAWING
An embodiment of the invention will now be described by way of example with reference to the drawings in which: FIG. 1 shows a first step of the method, FIG. 2 shows a second step of the method, and FIG. 3 shows a third step of the method in accordance with the invention and FIGS. 4a, 4b, 4c and 4d show alternative constructions of gripping means on one end of a device for use in the method.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring first to FIGS. 1, 2 and 3 the method of treating hair is carried out using a device 10. The device includes a tube 11 of elastic material open at both ends 12, 13. Initially the tube 11 is in an unextended state as shown in FIG. 1 and a tress of hair 14 is inserted such as to extend lengthwise along the tube with a free end 15 of the tress of hair projecting from the end 13 of the tube. A first gripping means 16 is used to secure end 12 of the tube, adjacent the scalp 17, to the tress of hair. The end 13 of the tube is pulled manually in a direction, indicated by arrow 18, away from the scalp 17 such as to extend the tube 11, to an extended state shown in FIG. 2, and thereby cover at least a part of the length of the free end 15 of the tress of hair. When the tube has been extended to a sufficient extent, a second gripping means 19 at the end 13 of the tube is used to secure the end 13 of the tube, while the tube remains held manually in its extended state, to the tress of hair. The gripping means 16 and 19 are effective to secure the ends of the tube to the tress of hair with sufficient force as to prevent slipping of the tress of hair relative to the ends of the tube.
When the end 13 of the tube is released, thereby removing the force holding the tube in its extended state, the tube contracts lengthwise such that the end 13 moves in the direction of arrow 20 and thereby draws the hair gripped at the end 13 of the tube toward the hair gripped at the end 12 of the tube. As a consequence the Length of the tress of hair contained within the tube is forced to occupy an overall length shorter than that of the tress of hair when lying straight and the tress of hair takes up a generally sinuous form 21, as shown in FIG. 3, within the confines of the contracted tube 11.
Prior to inserting the tress of hair into the tube, the tress of hair is treated with a chemical hair treatment substance effective to
