Devices and methods for styling hair, and in particular, to devices and methods for styling hair using electrolysis are described herein. A method for styling hair includes arranging a section of hair between a first electrode and a second electrode. The section of hair is contacted with an electrolyte before being arranged between the first and second electrodes, after being arranged between the first and second electrodes, and/or concurrently with being arranged between the first and second electrodes. The method further includes causing the first electrode to have a first negative potential, and causing the second electrode to have a second potential, such that the absolute value of the first negative potential is greater than the absolute value of the second potential, and such that the difference in electrical potential between the first electrode and the second electrode creates an electrolysis zone between the first electrode and the second electrode.

The present invention discloses a detachable power cord structure for a portable hair curler, including a device tail sleeve and a tail wire. An elastic engaging assembly is arranged in the device tail sleeve, the tail wire is inserted into the device tail sleeve, and is engaged with the elastic engaging assembly. When the tail wire is engaged into the elastic engaging assembly, it can turn on the circuit and can be rotated freely. The power connector structure adopted by the present invention can be rotated through insertion of the device tail sleeve and the tail wire, and the elastic engaging assembly is arranged in the device tail sleeve. The tail wire can be rotated freely while the electrical connection is realized, and the tail wire is not bent or curved during use, thereby effectively ensuring the service life of the tail wire.

A hair-shaping device comprising a winding core, a rotatably drivable entraining element with an axis of rotation which corresponds to the longitudinal axis of the winding core, the entraining element designed to grasp a strand of hair and to wind the strand of hair around the winding core, and a housing that encloses the winding core, wherein the radial distance of the inside of the housing from the lateral surface of the winding core in the region of a winding space is sufficiently large such that winding the strand of hair onto the winding core is not hindered. The housing comprises a slot extending in the direction of the longitudinal extent of the winding core. The entraining element is arranged inside the winding space. The slot is designed for inserting a segment of hair to be shaped into the winding space and extends into the housing part facing the hair pull-in side and bounding the winding space in this direction, such that a strand of hair inserted into the insertion slot is caught by the entraining element rotating inside the winding space. The housing has a warm air flow inlet for supplying heat to a strand of hair located in the winding space between the winding core and the housing.
