There is described a method for colouring hair, said method comprising treating hair with a composition comprising dihydroxyacetone (DHA), in free form or in salt form; optionally drying the hair; and heating the treated hair, including the applied DHA composition, to a temperature of from about 100° C. to about 250° C.

A hair perming device and its temperature control circuit are disclosed. The temperature control circuit for a hair perming device is electrically connected with a heater of the hair penning device and comprises a main control module and a trigger module. The main control module controls the trigger module to be switched on such that a control signal outputted by the main control module can be sent to the heater for heating, and meanwhile for detects a working state of the trigger module. When a failure of the trigger module is detected, the main control module controls the trigger module to be switched off such that a continuous heating of the heater is stopped. When a failure of the trigger module is detected, the electrical power supply path of the heater is disconnected, and a continuous heating of the heater is stopped for avoiding excessive high temperature.

A hair drying and twisting assembly includes an air gun that has a handle portion and a barrel portion. A cylinder is removably attachable to the barrel portion and the cylinder is foraminous to pass air therethrough. A blower is positioned within the barrel portion to blow air outwardly through the barrel portion when the blower is turned on. A heating element is positioned within the barrel portion to heat the air is blown by the blower when the heating element is turned on. A plurality of motors is positioned in the barrel portion and a plurality of coiled members is positioned within the barrel portion. Each of the coiled members engages a respective one of the motors to twist the user's hair into a coil when the motors are turned on.

A hair-styling tool may include one or more pods that store liquid. For example, the hair-styling tool may include a removable, reusable water pod and/or a removable oil-formulation pod, which may correspond to a hair type of an individual. Moreover, during operation, the hair-styling tool may output or provide one or more discharges, such as: a steam discharge, an oil-formulation discharge, and/or a steam-and-oil-formulation discharge. The discharge flow may be selectable or dynamically adjusted based at least in part on the hair type of the individual, a predefined preference of the individual, and/or a predefined preference of a hair stylist. Moreover, the one or more discharges may be output of or provided from a head in the hair-styling tool. This head may include multiple prongs or tines that are used, in conjunction with the one or more discharges, to detangle or style an individual's hair.

A hair styling device (1) comprises a hinge jaw assembly (10) including a first jaw (11) having a first plate (12) and a second jaw (13) having a second plate (14). In an opened position of the jaw assembly (10), hair can be received between the plates (12, 14), and in a closed position of the jaw assembly (10), hair can be hair styled between the plates (12, 14). The hair styling device (1) further comprises a heater arrangement (20) configured to heat at least one of the plates (12, 14), and a hair wetness control mechanism (30) configured to supply a mist of liquid between the plates (12, 14) in the closed position of the jaw assembly (10), wherein the hair wetness control mechanism (30) includes a two-fluid nozzle (31), and an air pump (33) and a liquid tank (35) connected to respective inlets of the two-fluid nozzle (31). Preferably, the hair wetness control mechanism (30) is arranged to suck liquid from the tank (35) as a result from a flow of air that is generated by the air pump (33), without a need for a separate pump to obtain a flow of the liquid in the two-fluid nozzle (31).

The present invention discloses a styling comb, the styling comb includes a handle, a hot comb head, and cold comb head, the hot comb head is provided with a heat-generating component and a thermally-conductive comb tooth component, the thermally-conductive comb tooth component is thermally conductively connected to the heat-generating component, and the thermally-conductive comb tooth component is used for combing hair; the cold comb head is provided with a refrigeration component and a thermally-conductive comb tooth component, the thermally-conductive comb tooth component is thermally conductively connected to the refrigeration component, and the thermally-conductive comb tooth component is used for combing hair; the cold comb head and the hot comb head are alternatively and removably mounted on the handle. The technical solution of the present invention can enhance the capability of styling comb to meet different use needs.

An attachment for a hair dryer that is intended to curl the user's hair during the drying process. The attachment includes a tubular first body, a tubular second body, a hair curling post, and a baffle. The tubular first body extends between a hair curling entrance and an attachment outlet, the first body also including an airflow entrance. The tubular second body that extends between an attachment entrance and a second body outlet, the second body outlet being coupled to the airflow entrance of the first body. The hair curling post extends through at least the inside of the first body. The baffle is operable to direct airflow through the first body in a generally circular manner about the hair curling post in a first direction at times the baffle is in a first position and in a second direction at times the baffle is in a second position.

An eyelash curler comprising a handle, an actuator, and a curling head. The handle has an elongated shape with a top end and a bottom end. The actuator is embedded within the handle with a switch exposed on the surface of the handle and an actuator stem extending from the top end of the handle. Manipulating the switch moves the actuator between a first position and a second position. The curling head has only one support bar, a first curler arm coupled to the end of the support bar, and a second curler arm coupled to the top end of the actuator stem. When the actuator is in the first position, the second curler arm is in contact with the top end of the handle and when the actuator is in the second position, the second curler arm is in contact with the first curler arm.

A hair styling aid for curling hair is described, including a housing, guide means comprising a slot in a wall of the housing for receiving a length of hair to be styled, a rotatable element rotatable clockwise or anticlockwise relative to the housing and the guide means, to form curls, and a heated elongate member around which the length of hair is wound by the rotatable element, in use. The housing surrounds a part of the elongate member to form a chamber between the housing wall(s) and the elongate member, the housing extending from and being integral with a handle. The rotatable element is rotatable relative to or with the elongate member, having a predefined starting position to which it is automatically returned after use. The housing has a longitudinal axis and the slot is parallel with the longitudinal axis of the housing.

A hair brush for use in a hairdressing store, a beauty shop, or at home, is able to easily and freely create a hair style by arranging flexible brush pins to a brush pedestal of the hairbrush so that the hair is easily entangled around the brush portion. The brush pedestal is further provided with a large number of hot air injection holes to inject hot air generated by a heater and a fan formed at an inside of the brush pedestal. Thus, hair styling using the hot air by one-handed operation is possible. Further, since the brush pedestal is heated by receiving the heat generated by the heater, the brush pedestal in contact with the hair becomes hot and thus an iron effect at the time of hair styling can be obtained.
