A hair iron includes a first elongated bar and a second elongated bar. The first elongated bar includes a first iron portion, a first fulcrum portion and a first grip portion, wherein the first iron portion includes a first heating pad where hair is to be ironed, and the first iron portion and the first grip portion are connected to and disposed at opposite sides of the first fulcrum portion. The second elongated bar engages with and is pivotally rotatable relative to the first elongated bar, and includes a second iron portion, a second fulcrum portion and a second grip portion, wherein the second iron portion includes a second heating pad that cooperates with the first heating pad to iron hair, and the second iron portion and the second grip portion are connected to and disposed at opposite sides of the second fulcrum portion. A first bending angle exists between the first iron portion and the first fulcrum portion, and a second bending angle exists between the second iron portion and the second fulcrum portion.

In a hair styling device (20) having a two-dimensional array (21) of elements to bring hair at a styling temperature, the elements produce optical radiation energy. The elements may include one or more LEDs, and preferably a plurality of LEDs, in which case the LEDS are driven in clusters that may be of mutually different shapes and sizes. The hair styling device (20) further comprises sensors to obtain an areal light absorption measurement opposed to the two-dimensional array of elements, and a control unit for individually controlling the elements in dependence of the measurement. The sensors may be arranged for measuring an areal light density profile of a whole treatment area. The hair styling device may radiate hair from two sides, both of which includes an areal light absorption measurement. The sensors may include LEDs that do not produce light.

An automatic curling iron includes at least two parallel prongs defining a gap aligned along a longitudinal axis. A rotation mechanism drives at least one of the prongs around the longitudinal axis. A thermally insulated handle holds the revolving mechanism with the two prongs extending. An electrical circuit housed in the housing powers the revolving mechanism heats at least one of the prongs. Optionally, the apparatus includes a stationary outer styling shell coupled to the housing and enclosing at least a portion of the prongs. The outer styling shell can be separated into sections so enable access to the gap and may be expandable. One or more fins of elastomeric high temperature material may be mounted to an interior of the styling shell and positioned to hold strands of hair against a heated one of the prongs.

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.

A hair-styling device may include a pair of articulated jaws having respective heating plates. At least one cartridge configured to contain a liquid may be included in one of or both of the jaws. The cartridge includes an ultrasonic transducer with micro-perforations configured to transform the liquid into a dispersion of droplets, and an outlet configured to deliver the dispersion of droplets, through a delivery cavity situated in at least one of the heating plates, to discharge ports distributed over a surface of the heating plate.
