The invention relates to a tank (2) intended for containing a liquid to be vaporised and for being assembled with a main body (1) of a hairdressing apparatus, said tank (2) being intended for being connected with a vaporising device of the hairdressing apparatus designed for vaporising the liquid and diffusing it towards a strand of hair. According to the invention, the tank (2) has a movable hooking device (3) comprising at least one hooking means designed to correspond with at least one complementary hooking means belonging to the main body (1) so as to hook the tank (2) with the main body (1), said movable hooking device (3) being movable between a first position providing the hooking of the tank (2) with the main body (1) and a second position allowing a user to assemble or disassemble the tank (3) with the main body (1).

A method for the permanent shaping and color modification of keratinic in a single process includes the following steps. First, an aqueous composition, including at least one keratin-reducing compound and at least one alkalizing agent, is applied to the keratinic fibers and is left on the keratinic fibers for a period of 5 to 50 minutes at a temperature of 20 to 45° C. The keratinic fibers are rinsed, and optionally dried. Next, a composition including at least one oxidation dye precursor and at least one oxidizing agent is applied to the keratinic fibers and the keratinic fibers are deformed. That composition is allowed to act for 10 to 35 minutes. An aqueous composition including at least one oxidizing agent, is applied to the keratinic fibers for 30 seconds to 15 minutes. The keratinic fibers are rinsed out, along with removal of the deformation aids.

Method for simultaneously and permanently reshaping and coloring keratin fibers, particularly human hairs, in a single process in which the keratinic fibers are first waved by means of a foam-type waving agent (M1) and then lightened or colored by means of a foam-type coloring agent (M2). The permanent wave is simultaneously fixed by the oxidizing agent included in the oxidative dyeing agent. The method according to the invention brings about a uniform waving and coloring result and causes little or no damage to the hair.

In a hair styling device (100) comprising electrodes (102) for applying a radio-frequent signal to hair, a frequency of the radio-frequent signal is between 50 MHz and 90 MHz. Preferably, a voltage of the radio-frequent signal does not exceed 30 V, while a voltage not exceeding 10 V would work well in a configuration that applies another heat source (103) for heating hair up till a first temperature that is no more than 150° C. (and thus lower than a critical temperature at which hair cuticle damage will occur), and the radio-frequent electrodes (102) for in combination with heat from the other heat source (103)—selectively heating a hair cortex to a second temperature exceeding the first temperature and sufficiently high for hair styling.

A process for permanently reshaping keratin fibers comprising mixing a component A and a component B to form a reducing composition. The component A comprises at least one thiol-based reducing compound having one thiol group selected from the group consisting of thioglycolic acid and derivatives thereof, thiolactic acid and derivatives thereof, 3-mercaptopropionic acid and derivatives thereof, and cysteine and derivatives thereof, and has pH 7.0 or less and the component B comprises at least one buffer salt selected from the group consisting of carbonates, bicarbonates and carbamates, and has pH 8.0 or more, wherein at least one of the component A and component B comprises at least one disulfide compound that is further defined, and wherein the reducing composition has a pH ranging from 7.0 to 7.8 and a viscosity ranging from 500 cps to 100,000 cps. The reducing composition is then applied to the keratin fibers.

In a hair straightener comprising an elongate straightener arm (A) having a heating plate (H), the invention provides a pivot mechanism (2) for supporting the heating plate (H) in a pivotable manner around a pivot axis (P1) in a longitudinal direction of the elongate straightener arm (A). Preferably, the pivot axis (P1) is at a heating surface of the heating plate (H), or between a first heating plate of a first straightener arm and a second heating plate of a second straightener arm when the first straightener arm and the second straightener arm are in a relative position arranged for clamping hair. Advantageously, a bias mechanism (4) (e.g. a resilient member like some spring) biases the heating plate (H) to a neutral position.

A rechargeable hair styling tool may be plugged into an electrical outlet to enable charging of each battery and operation of the hair styling tool. Electronics of the hair styling tool may enable it to alternately operate under power from the battery or batteries (i.e., stored power) while the hair styling tool is unplugged from an electrical outlet (e.g., a wall socket, etc.) and under power of an external source of electricity while the hair styling tool is plugged into the electrical outlet. Each heating element of such a rechargeable hair styling tool may be heated when the hair styling tool is plugged in and, once each heating element has been heated to a sufficient temperature, continue to function under power supplied by the battery or batteries of the rechargeable hair styling tool.

A hair care device (B) comprises an ion generator (I), and a grounding protrusion protruding from the hair care device (B). When the hair care device comprises a sensor (MP), and ancillary elements (AE, G) for guiding hair to or along the sensor (MP), the grounding protrusion advantageously includes at least one of the ancillary elements (AE, G).

The present invention relates to a multi-functional hair-styling thermal treatment beauty device, which continuously rotates, in a clockwise or counterclockwise direction, a hair-styling part for holding hair while holding body part is held or can open an upper rotary body of the hair-styling part so as to enable hair styling to be easily performed. according to circumstances, and forms continuous grounding structure so as to enable power to be continuously supplied to a heating plate mounted inside the hair-styling part capable of continuously rotating, so that the heated state of the heating plate, caused by the heating of a current, is continuously maintained even during continuous rotation, and thus various hair styles can be more effectively created by the hair-styling part, so that hair styling is easily performed according to circumstances, and operation fatigue is reduced so that use convenience can. be improved.

A hair straightening apparatus having two arms pivotably coupled together and arranged to receive hair within a cavity formed between them is disclosed. A plenum in at least one arm includes an air inlet for receiving airflow from a fan unit and an air outlet for emitting airflow towards hair within the cavity. The air outlet extends along the inner wall of at least one of the first arm and the second arm and is adapted to direct airflow towards a lower edge of the arms.
