Device and method for shaping and treating keratin fibres such as the hair

A method for shaping a strand of hair or other keratinous fibers, comprising:

• providing a device for receiving at least one strand of hair or other keratinous fibers, the device having at least one strand-receiving surface configured to enable the formation of, from at least one strand of hair or other keratinous fibers, at least two undulations having winding axes that are not colinear with one another and/or are of different diameters, the device being in the form of a case comprising a distal end and a proximal end, said distal end having an opening, wherein the strand-receiving surface is at least partially made from hemp;
• positioning a strand of hair or other keratinous fibers so that at least a portion of the strand is in contact with at least one surface of said device;
• wetting the strand;
• performing twisting movements of the device along its length (L) by at least partially holding the strand in contact with said at least one surface of said device in order to interlace the strand with the device taken along its length (L);
• laterally tightening the device at a plurality of points to hold the strand against the at least one surface of the device;
• folding back the device to insert at least part of the proximal end into said opening.

A device for receiving at least one strand of hair or other keratinous fibers and having at least one strand-receiving surface configured to enable the formation of, from at least one strand of hair or other keratinous fibers, at least two undulations having winding axes that are not collinear with one another and/or of different diameters,

• wherein said device has the shape of a case,
• wherein the device comprises a distal end and a proximal end, said distal end having an opening intended to receive, in a folded position of the device, at least the part of the device comprising said proximal end,
• wherein the device comprises a slide forming or close to the edge of said opening, and two straps able to tighten said opening by sliding in said slide, said straps further forming means for attaching said distal end with said proximal end, and
• wherein the device is made, at least partially in its strand-receiving surface, of hemp.
