A hair treatment device includes a main body and a housing. The main body includes a tool bit device. The housing includes an accommodating cavity. The tool bit device is movably accommodated in the accommodating cavity in a telescopic manner. When the tool bit device is accommodated in the accommodating cavity, the tool bit device is automatically turned off; and when the tool bit device extends out of the accommodating cavity, the tool bit device is automatically turned on. According to the hair treatment device of the present disclosure, the tool bit device is movably accommodated in the accommodating cavity in the telescopic manner, so that the tool bit device is effectively protected. Meanwhile, the tool bit device is disposed to be automatically turned on or turned off, which is not required to manually operate a control switch to control an on-and-off state of the tool bit device.

A refill for a device for treating hair, including: a reservoir of elongate shape along a longitudinal axis, defining a cavity containing a cosmetic composition to be applied to the hair, the reservoir having a flank for mounting the refill on the device, extending parallel to the longitudinal axis of the reservoir, a porous application member for applying the cosmetic composition to the hair, of elongate shape and extending parallel to the longitudinal axis of the reservoir. The application member being fitted in a slot-shaped opening in the reservoir that leads into the cavity, this opening being offset laterally toward the mounting flank, relative to a median plane of the cavity that contains the longitudinal axis of the reservoir and is parallel to the mounting flank.

Hairstyling devices include one or more heat transmissive elements having a coating disposed thereon, the coating having ceramic and lava rock incorporated therein. The use of lava rock-containing coatings as described herein results in hairstyling devices with heat transmissive elements exhibiting enhanced heat retention, faster heat recovery, and increased ion emission. Furthermore, lava rock-containing coatings have been found more durable than equivalent heat transmissive element coatings that do not have lava rock incorporated therein.

A method for treating the hair with the aid of a treatment device, notably a heat treatment device, in particular a straightening device, in which a lock of hair is exposed, while the device is being moved along the latter, in a single operation to: apply cosmetic composition with the aid of an application member of the device, and then to apply steam with the aid of a steam outlet of the device that is offset relative to the application member in the direction of movement of the lock of hair by a nonzero distance v, measured between the median plane of the steam outlet and the median plane of the application member, of less than or equal to 10 mm.

The three-in-one marcel waver with curling method in the field of hairdressing device is described, including the first hairdressing section, the second hairdressing section and a base. The first hairdressing section is movably connected to the base, and the second hairdressing section is fixedly connected to the base. The second hairdressing section consists of perming unit, combing unit, and switch button, with perming unit and switch button at the inner side, and the combing unit at the outer side. The perming unit links the second hairdressing section thanks to the arc-shaped transitional edges designed laterally. The combing unit comprises the first comb, the second comb, holder, the second comb hole, and the first comb hole. The holder has the second comb hole and the first comb hole. The invention features the integrated design of splint, electric comb and hair curler, meeting the needs of various hairstyles of terminal customers, and providing better user experience by catering to consumer demand.
