Definitions

• the invention relates to ultrasonic hair styling, such as ultrasonic hair curling, crimping, or straightening.
• US 6,196,236 discloses an ultrasonic hair curling device capable of applying ultrasonic vibration efficiently to hairs for effective hair styling in a short time.
• the device includes a housing, an ultrasonic generator incorporated in the housing for generating ultrasonic vibrations, and a horn connected to receive and transmit the ultrasonic vibrations at a frequency of 20 kHz to 100 kHz.
• the horn is formed at its end with a hollow barrel which projects from the housing for receiving therearound a strand of hair to be curled.
• the hollow barrel is provided at a portion intermediates at its longitudinal ends with a hair winding zone of which cross-section is smaller than the other portion of the hollow barrel.
• the hair winding zone of the reduced cross section can vibrate at an amplitude larger than at the front end of the barrel for applying the ultrasonic vibrations efficiently to the hair and making the hair curling effectively.
• EP 1 728 450 discloses an ultrasonic hair treatment device to apply ultrasonic vibrations to a user's hair for enhancing the penetration of a hair treatment composition into the hair.
• a piezoelectric transducer produces vibrations of 500 kHz to 10 MHz frequency at a power of 0.1 to 5 W/cm 2 .
• an object of the invention to provide a more effective ultrasonic hair styling without using chemicals to obtain the hair styling effect.
• the invention is defined by the independent claims.
• Advantageous embodiments are defined in the dependent claims.
• the expression "to get a non-chemical hair styling” is meant to reflect that no chemicals are used to obtain the hair styling effect, i.e. the hair styling effect directly results from applying ultrasound, possibly to hair that is mechanically put into a certain shape (e.g. by winding it around a rod, or by stretching), which shape is retained as a result of applying ultrasound to the hair.
• the ultrasound frequency should be at least 1 MHz, and preferably exceeds 1 MHz.
• the ultrasound frequency is between 1 and 100 MHz, preferably between 3 and 10 MHz, and more preferably between 3 and 5 MHz.
• the hairs are styled by the MHz ultrasound waves, which involve a combination of heating due to the dissipation of the wave and mechanical displacement of the ultrasound propagation through the hair. In the kHz range, the thermal effect is not present due to low dissipation of the ultrasound at these frequency.
• the frequency is lowered, the thermal effect decreases and the mechanical effect increases, while if the frequency is increased, the mechanical effect decreases and the thermal effect increases.
• the hairs would be damaged in a similar way as in standard thermal curling devices.
• the ultrasound wave will be dissipated within the first layer of hairs and thus the next layers will not have any effect from the ultrasound, and the curling would then rely only from the heat diffusion in a similar way to a hot plate as in usual thermal curling devices, which may result in damaging the hair.
• Figs. 1 to 4 illustrate embodiments of a hair curler device in accordance with the present invention
• Fig. 5 shows an embodiment of a hair crimper or waver device in accordance with the present invention.
• Fig. 6 shows an embodiment of a hair straightening device in accordance with the present invention.
• Fig. 1 illustrates a first embodiment of a hair curler device in accordance with the present invention.
• Hair H is wound around a cylindrical rod, and an ultrasonic transducer UST, preferably using PZT or CMUT technology, moves and presses the hair.
• PZT stands for Lead Zirconate Titanate
• CMUT stands for Capacitive Micromachined
• Fig. 2 illustrates a second embodiment of a hair curler device in accordance with the present invention.
• the ultrasonic transducer UST is embedded inside the cylindrical rod on which the hair H is wound around.
• Fig. 3 illustrates a third embodiment of a hair curler device in accordance with the present invention.
• ultrasonic transducer UST generates the ultrasound waves which are coupled into the conical rod R.
• the hair H is wound around the conical rod R.
• Fig. 4 illustrates a fourth embodiment of a hair curler device in accordance with the present invention.
• the ultrasonic transducer UST generates the ultrasound waves which are coupled into a cylindrical rod R containing features F.
• the hair H is wound around the cylindrical rod R within the features F.
• the features F may be slots with a width between 0.2 mm and 4 mm.
• the surface of the rod as illustrated in the previous embodiments may contain features smaller than 0.2 mm. These features may be made from the rod material itself or from an additional coating on the rod.
• Fig. 5 illustrates an embodiment of a hair crimper or waver device in accordance with the present invention.
• ultrasonic transducer UST generates the ultrasound waves which are coupled into two similar rods R mounted on the upper side of a clamping device.
• a third rod with two recesses on its sides are mounted on the lower side of the same clamping device such that when the hair H is placed in between the upper and lower sides of the clamping device and the clamping device is clamped by the user, the third rod sits between the first and second rods, pressing the hair into a crimped or waved shape as shown in Fig. 5.
• the invention for hair straightening.
• the curled hair needs to be placed straight before applying the treatment. This can be done by stretching the hair, but also by guiding the hair before clamping it between two plates. In fact, if the hairs are simply clamped in their original curled shape, the straightening effect would not work.
• Another embodiment would be a hair stretching element placed in front of the ultrasound transducer to stretch the hair before treatment.
• Yet another embodiment would be a comb placed in front of a clamp to guide the hair straight into the clamp, the clamp being made of an ultrasound transducer.
• Fig. 6 illustrates an embodiment of a hair straightening device in accordance with the present invention.
• ultrasonic transducer UST generates the ultrasound waves on a plate on the lower or upper side of a clamping device.
• a stretcher S is mounted on one side of the plate such that when the hair H is placed in between the upper and lower sides of the clamping device, the clamping device is clamped by the user and the device is moved, the stretcher S stretches the hairs clamped between the two plates to form a straight shape.
• Embodiments of the invention thus provide an ultrasonic treatment of hair whereby a larger volume of hair can be treated in order to get hair styling without any chemicals and without any thermal damage to the hair as it is done in hot iron styling devices.
• the hair styling by means of ultrasound using the parameters described herein is done not by heating the hair or using chemicals but by mechanical way of breaking hydrogen bonds to style hairs using ultrasound.
