Abstract: In order to be able to sheath a lock of hair (5) using a hose (1) in a simple and easy to manipulate manner, a device is proposed comprising a sleeve (2), a deformable hose (1) that can be placed on the sleeve (2), and a gripper element (8), which can be guided through the sleeve (2) and is longer than the sleeve (2), the gripper element (8) having a hook (4) on one end for grasping a lock of hair (5) and a handle (3) on the other end for manually holding the gripper element (8). In order to apply a hose (1) to a lock of hair (5), the hose (1) is first pulled in cylindrical form over the sleeve (2). Then the lock of hair (5) is grasped using the hook (4) and pulled through the sleeve (2). Then the sleeve (2) and the gripper element (8) are detached from the lock of hair (5) and pulled out of the hose (1).
