• the reel stops in its starting position after the wick is wound, after a number of rotations of said reel, and once the winding device stopped by the user.
• the hairdressing apparatus comprises electronic control means which measure the rate of rotation of a motor driving the winder. When this rotation rate does not reach a determined threshold, this indicates that an unacceptable load is applied to the winder, representative of a possible hair jam on the hair styling apparatus.
• the electronic control means then reverse the direction of rotation of the motor until the retractor reaches its starting position, in order to release the lock of hair and allow its removal.
• hairdressing devices for the hair looping whose electronic control means measure a defined number of rotations of the winder, for example by using a magnet placed on the winder and a magnetic field sensor placed on the body of the hair styling apparatus.
• These electronic control means are furthermore configured to detect when the consumed power or the duration of rotation exceeds a threshold before the retractor succeeds in making a complete revolution, that is to say before the magnetic field sensor detects the passage of the magnet again.

Indeed, the power consumed is dependent on the adjustments and is therefore not identical between all hairdressing appliances of the same type. As a result, the difference between the nominal measurement of power consumed and the value of the consumption threshold varies between hairdressing appliances of the same type. Similarly, each motor has a rotation speed tolerance, which implies a variation of the gap between the measurement of the time between two passes of the magnet and the threshold of duration between hairdressing appliances of the same type. .

• the stop step is also activated as soon as the reference unit reaches a predefined threshold value (T). In another variant embodiment, the stop step is also activated as soon as at least one of the following conditions is fulfilled:
• said retractor reaches a reference position while the reference unit has reached or exceeded a first predefined threshold value (T, P),
• the reference unit reaches a second threshold value (T + Ts, P + Ps) predefined, greater than the first threshold value (T, P).
• the method comprises, prior to the step of rotation of the reel triggered by the activation of the control member, an initialization step in which the winder is brought into a predetermined starting position, if it does not already occupy this position.
• This predetermined starting position allows the introduction of the lock of hair into the apparatus hairdressing and seizure of this lock of hair by the winder, for its winding around the mandrel.
• the reference unit is the time t.
• the first threshold value T is greater than 3 seconds and, preferably, is of the order of 4 seconds.
