1. A hairdressing tool comprising:

a slender, circumferentially continuous tubular hair holder having a hair inlet at one end thereof and comprising a flexible material,

a hair inserter for inserting hair in or through the hair holder, the hair inserter being capable of being introduced in the slender tubular hair holder to grasp hair and insert the grasped hair through the hair holder, and

curling means for rolling, curving or bending the hair held in the hair holder into a prescribed shape by contracting at least the length dimension of the hair holder sufficiently to roll, curve or bend the hair held in the hair holder, wherein the curling means comprises a thread being threaded through the hair holder at several points along the length of the hair holder.

2. The hairdressing tool according to claim 1 , wherein the hair inserter has a hair catching member and is adapted to be inserted in the hair holder with the hair catching member being disposed by the side of the hair inlet of the hair holder.

3. The hairdressing tool according to claim 2 , wherein the hair catching member is a loop the circumference of which is larger than the circumference of the hair inlet, and the hair catching member is deformable.

4. The hairdressing tool according to claim 2 , wherein the hair catching member has comb teeth.

5. The hairdressing tool according to claim 1 , wherein the hair inlet and the vicinity thereof are more rigid than the other part of the hair holder.

6. The hairdressing tool according to claim 1 further comprising an auxiliary inserting member, wherein the auxiliary inserting member has an inlet, an outlet, and a passageway connecting the inlet and the outlet in the longitudinal direction thereof, the passageway having a decreasing diameter from the inlet toward the outlet, the hair inserter has a pulling member which passes through the passageway from the inlet to the outlet and then enters the hair holder through the hair inlet.

7. The hairdressing tool according to claim 1 , wherein the hair holder has a first side and a second side opposite to the first side, and the first side is provided with a joining member capable of joining the first side to the second side or to itself when the hair holder is rolled, curved or bent into a prescribed shape and thereby capable of maintaining the prescribed shape.

8. The hairdressing tool according to claim 1 , wherein the other end of the hair holder is adapted to be opened and closed.

9. The hairdressing tool according to claim 1 , wherein the hair holder has a hair treating agent applied to the inner side thereof.

10. The hairdressing tool according to claim 1 , wherein at least the part of the hair holder corresponding to half the circumference of the tube's cross-section has a Taber stiffness of 0.4 mN·m or less over the whole length of the hair holder.

11. The hairdressing tool according to claim 1 , wherein the hair holder has extensibility in the width direction.

12. The hairdressing tool according to claim 1 , wherein the hair holder is a tube formed by folding a rectangular sheet in half along its length and joining the longer sides together.

13. The hairdressing tool according to claim 1 , wherein the hair holder is a tube formed by joining two rectangular sheets together along their longer sides, and at least one of the sheets has a Taber stiffness of 0.4 mN·m or less.

14. The hairdressing tool according to claim 1 , wherein the hair holder is a tube formed by folding an extensible rectangular sheet in half along its length and joining the longer sides together to form a joint, and the joint along the longer side has no extensibility.

15. The hairdressing tool according to claim 1 , wherein the hair holder has the hair inserter previously attached thereto.

16. The hairdressing tool according to claim 1 , wherein the hair holder is permeable or impermeable to a hair treating agent.

17. The hairdressing tool according to claim 1 , wherein the thread pierces the hair holder in a zig-zag trace at several positions along the length of the hair holder.
