Description

CROSS-REFERENCE TO RELATED APPLICATION

This application is a U.S. National-Stage entry under 35 U.S.C. § 371 based on International Application No. PCT/EP2018/067829, filed Jul. 2, 2018, which was published under PCT Article 21(2) and which claims priority to German Application No. 10 2017 211 781.8, filed Jul. 10, 2017, which are all hereby incorporated in their entirety by reference.

TECHNICAL FIELD

The present disclosure relates to hair cosmetics, in particular to a hair treatment system, and to a method for the cosmetic treatment of hair.

BACKGROUND

Users (also termed consumers) frequently do not know to what extent their hair has been damaged, and moreover, frequently know little about the condition of their hair. The condition of the hair, and in particular the degree of damage to the hair, can vary widely depending on treatment history and the nature of the hair. This information may be important when selecting a correct cosmetic hair treatment, i.e. a cosmetic treatment that is appropriate for the degree of damage to the hair, and/or a cosmetic hair treatment agent.
For semi-permanent hair styling which may, for example, be carried out using a hair straightener and/or curling wand or a similar device, hair treatment agents (for example chemical hair treatment agents) may be used which can reinforce the action of the mechanical devices which are used for styling the hair. Hair straighteners, curling wands and similar devices are also generally known here as small electrical appliances.
For semi-permanent hair styling, in order to obtain the cosmetic effect, the structure of the hair is altered. This occurs, for example, by heating the hair when using a hair straightener or curling wand. This process could possibly be damaging to the hair because of the high temperatures used (from about 120° C. to about 240° C.). In particular, hair which has already been damaged could be severely (further) damaged if semi-permanent hair styling is incorrectly carried out, for example by applying too much heat with a hair straightener.
Accurately coordinating the temperatures and/or cosmetic conditioning agents used during straightening could therefore be very important when styling semi-permanently.
Non-professional people in particular may lack knowledge regarding how to obtain a semi-permanent shaping of the hair using small electrical appliances (for example straightening using a hair straightener or curling the hair using a curling wand), without damaging the hair. Furthermore, they may not know how to obtain an optimum result under specific climatic conditions.
Effective shaping of the hair can usually only be obtained at temperatures from approximately 190° C. or higher. Beyond this temperature, damage to the hair may be observed.
There is therefore a requirement for a hair treatment method or a hair treatment system which allows hair to be treated gently.
Furthermore, it would be desirable for the user to be able to obtain an objective assessment of a treatment outcome and/or a treatment procedure during a cosmetic hair treatment.

In various exemplary embodiments, the sensor may have a hair damage sensor. The hair damage sensor may, in various exemplary embodiments, be configured to determine an amino acid oxidation product content, in particular a cysteic acid content, of the hair by employing near-infrared spectroscopy and/or fluorescence spectroscopy and to determine a degree of damage to the hair from it. The hair damage sensor may, in various exemplary embodiments, be configured to determine a content of one or more amino acid(s) in the hair by employing near-infrared spectroscopy and to determine a degree of damage to the hair from it. In various exemplary embodiments, the hair damage sensor may be configured to record acoustic emissions captured during combing of the hair and to determine the degree of damage to the hair from it, optionally with the aid of the processor.
In various exemplary embodiments, the hair damage sensor may have a microscopic photosensor. The microscopic photosensor may be configured to determine the roughness of the surface of the hair or to enable the roughness of the hair surface to be determined.
In various exemplary embodiments, the hair damage sensor may have a camera which may be coupled to an interference reflection microscope of the sensor device.
In various exemplary embodiments, the sensor may have a hair thickness sensor. In various exemplary embodiments, the hair thickness sensor may be configured to determine a thickness of the hair by employing a light sensor. As an example, when determining the hair thickness, the fact that thicker hair absorbs more light may be taken into consideration. In this regard, in various exemplary embodiments, the hair thickness sensor may be configured such that a specific quantity of hair, for example a single layer, can be introduced into a specific volume and the volume is irradiated with light of a predetermined intensity, whereupon the quantity of light which reaches the sensor after passing through the hair can be measured by employing the sensor. The hair thickness can be determined with the aid of the captured light by employing the hair thickness sensor, optionally in conjunction with the electronic circuit device, for example the processor.
In various exemplary embodiments, for example in a case in which the hair thickness sensor has a colour camera, the hair thickness sensor may also be used to determine a hair colour, optionally with the assistance of the electronic circuit device.
In various exemplary embodiments, the hair thickness sensor may have an ultrasound sensor. The ultrasound sensor may be configured to beam ultrasound waves in the direction of the hair, to capture ultrasound waves reflected by the hair and to determine the thickness of the hair from it, optionally in conjunction with the processor.
In various exemplary embodiments, the at least one sensor may be a hair length sensor. The hair length sensor may, for example, have at least one position sensor which allows a path length to be determined for the hair. In various exemplary embodiments, the hair length sensor may be combined with a sensor for calculating a combability of the hair (see below).
In various exemplary embodiments, instead of determining the length of the hair using the hair length sensor, the length of the hair is or may be provided by the user. As an example, the user may measure the hair length themselves and provide the value measured for the length of the hair to the hair treatment device or to the hair treatment system.
In various exemplary embodiments, the hair thickness sensor may have a photo-optic sensor in which an image of at least one hair is recorded.
In various exemplary embodiments, the hair thickness sensor may have a thermal sensor.
In various exemplary embodiments, the sensor may have a straightness/curliness sensor which may be configured to determine a structure of the hair in the context of smooth hair up to curly or frizzy hair. In various exemplary embodiments, the straightness/curliness sensor may have a camera. In various exemplary embodiments, the straightness/curliness sensor may be configured, optionally in conjunction with the electronic circuit device, for example the processor, for example by employing an image processing program, to determine the straightness or curliness of the hair.
In various exemplary embodiments, the sensor may have a hair moisture sensor. The hair moisture sensor may, in various exemplary embodiments, be configured to determine a water content of the hair. The hair moisture sensor may, for example, be set up as a near-infrared spectroscope which is configured to investigate near-infrared (NIR) absorption structures of water and, on the basis of these, optionally with the aid of the processor, to determine the hair moisture.
In various exemplary embodiments, the at least one sensor may have a combing work sensor. The combing work sensor may be configured to capture a force which is expended during combing of the hair (for example by employing strain gauges).
In various exemplary embodiments, the at least one sensor may have a hair density sensor. As an example, the hair density sensor may have a camera or a camera attachment which may be configured to be held directly against a region of the hair roots, for example by placing it directly onto the scalp. A density of the hair may be used to determine the hair density with the aid of the image, for example with the aid of a number of hairs and/or a distance between the hairs.
In various exemplary embodiments, the sensor, for example in the case of a spectrometer or a camera, may be configured to determine a plurality of hair condition parameters, for example both the degree of damage to the hair by employing the cysteic acid absorption structures in the NIR spectrum, as well as the hair moisture with the aid of the water absorption structures in the NIR spectrum.
In various exemplary embodiments, the sensor may be configured to determine further hair condition parameters.
In various exemplary embodiments, the sensor device may comprise at least one sensor which is configured to capture an environmental parameter. In various exemplary embodiments, the environmental parameter is captured in the open air.
The environmental sensor may, for example, comprise a thermometer which may be configured to capture an environmental temperature, an air humidity sensor to capture a humidity of the environmental air, a wind sensor, or the like.
Alternatively, in various exemplary embodiments, an environmental parameter may be provided via an external source. In various exemplary embodiments, the environmental parameter is not a contemporaneously captured parameter, but a predicted environmental parameter determined at a point in time specified by the user. As an example, the environmental parameter may be provided to the user via internet portals, internet sites, databases or apps, for example weather forecasting apps, and the user provides this to the hair treatment system, for example by employing an input device. Alternatively, the environmental parameter may be provided directly, for example via a weather forecasting app integrated into the hair treatment system or communicating with it, and will be taken into consideration in the method for the cosmetic treatment of a user's hair.
In various exemplary embodiments, the at least one environmental parameter, which is determined from the at least one environmental sensor and/or is provided via an external source, is taken into account when controlling or regulating the hair treatment. As an example, a temperature during the hair treatment may be higher and/or a treatment period during the hair treatment may be longer and/or a hair treatment agent with a stronger action may be applied to the hair and/or a higher force may be exerted on the hair when the determined at least one environmental parameter leads to the conclusion that the treated hair is exposed to a relatively high environmental stress (for example strong wind and/or low temperature and/or high air humidity (when hair is to be straightened) or low air humidity (when hair is to be curled). In contrast, a temperature during the hair treatment may be lower and/or a treatment period during the hair treatment may be shorter and/or a hair treatment agent with a weaker action may be applied to the hair and/or a lower force may be exerted on the hair when the determined at least one environmental parameter leads to the conclusion that the treated hair is exposed to a relatively low environmental stress (for example with a light or no wind, and/or average temperature and/or low air humidity (when hair is to be straightened) or high air humidity (when hair is to be curled).
In various exemplary embodiments, the hair treatment device of the hair treatment system may have or be an appliance which can be heated, for example a hair straightener or a curling wand or the like. This means that the hair treatment device in various exemplary embodiments may have a heating device as a hair treatment unit. In various exemplary embodiments, depending on the result of the hair analysis (damage, hair thickness, curliness, water content) and/or the environmental analysis, the heating device may be controlled or regulated.
As an example, in the case of more intact, thicker, curlier and/or wetter hair and/or in the case of more severe environmental conditions to which the hair is exposed (for example stronger wind, higher temperature), the hair treatment device or the hair treatment system may be controlled or regulated in a manner such that the hair is treated at a higher temperature than when the hair is more damaged, thinner, straighter and/or drier.
In various exemplary embodiments, the hair straightener or the curling wand, as a hair treatment unit, may have a device which is configured to carry out mechanical work on the hair, for example to press or pull the hair. To this end, the device may be equipped with a motor. The pressure or tension may be controllable or regulatable by employing the (for example electronically controllable) motor.
In various exemplary embodiments, instead of the motor or in addition thereto, the hair straightener or the curling wand may have at least one sensor which is configured to measure a force which is exerted on the hair, i.e., for example, a traction force sensor or a pressure sensor. This type of sensor, which is used during the hair treatment, is also termed herein a treatment sensor.
In the case in which the motor is present, the force exerted on the hair may be regulated with the aid of the values determined by the traction force sensor or pressure sensor, for example in a manner such that a predetermined force is obtained.
In the case in which the force is exerted on the hair manually, this may be determined by the traction force sensor or pressure sensor, and the user or person who exerts the force can receive feedback, for example visually or acoustically, for example so that the person can adjust the force exerted by them in order to obtain a predetermined force.
In various exemplary embodiments, the sensor device, as part of the hair treatment device or as a separate device, may have a plurality of sensors (for example identical) which, for example, may be disposed in a manner such that the user can immediately obtain feedback as to whether a further treatment (also termed “post-treatment”) is necessary.
In various exemplary embodiments, the hair treatment device may have sensors at two positions along a direction of movement of the hair, wherein one sensor measures a hair condition parameter prior to the hair treatment (for example the temperature treatment and/or the treatment with the hair treatment agent) and one sensor measures a (for example the same) hair condition parameter after the hair treatment.
In this respect, these sensors can be considered to be treatment sensors.
In various exemplary embodiments, the hair treatment device may have an application device for applying the hair treatment agent to the hair. The application device may, for example, be a reservoir, also termed a tank or cartridge, and a dispensing device, for example at least one (for example electronically controllable) valve and/or a (for example electronically controllable) pump device. The dispensing device may be formed as part of the tank, and/or as part of a body of the hair straightener/curling wand, also termed the device body.
In various exemplary embodiments, the cartridge may be refillable.
The hair treatment agent, for example a styling agent, may be placed in the reservoir. Depending on the results of the hair analysis (for example damage, hair thickness, curliness, water content) and/or the environmental analysis (for example wind, temperature, humidity), the hair treatment agent which, for example, may have a (for example chemical) composition, may be applied to the hair by actuating the dispensing device using the actuator.
In various exemplary embodiments, different volumes/quantities may be applied to the hair or may be applicable to the hair as a function of the position (for example roots, middle, ends).
In various exemplary embodiments, by employing the hair treatment system, two or more agents may be applied to the hair or may be applicable to the hair as a function of the position (for example roots, middle, ends), or at different positions.
In various exemplary embodiments, a user may obtain information regarding the progress of the application even while a hair treatment is being carried out. A hair treatment result may still be optimized while carrying out the hair treatment, so that frustration can be avoided.
In various exemplary embodiments, a hair treatment system with a hair treatment device may be provided in the form of a hair straightener or a curling wand, in which the at least one sensor is a part of a separate communication-enabled (i.e. comprising a data exchange device) sensor device (for example a smart phone which has a camera, a spectrometer with the data exchange device, what is known as an “acoustic comb”, which may be configured to capture sounds generated during combing and to transmit them.
An electronic circuit device which may have a processor, and a first actuator which may have an application device for a hair styling agent, may be integrated into the hair straightener or into the curling wand.
In various exemplary embodiments, the hair straightener or the curling wand may have a temperature control or a temperature regulator as a further actuator, which controls or regulates a temperature of heatable surfaces of the hair straightener or curling wand.
As an alternative or in addition, in various exemplary embodiments, the hair straightener or the curling wand may have one or more further actuators, for example to control or regulate a pressure which is exerted on the hair by employing the hair treatment device.
In various exemplary embodiments, the hair straightener or the curling wand may have a data exchange device, for example to receive measured values captured by the at least one sensor and/or to receive hair treatment parameters, for example control instructions.
In various exemplary embodiments, instead of being a part of the separate communication-enabled sensor device, or (for example in the case of a plurality of sensors) as a supplement thereto, the at least one sensor may be integrated into the hair straightener or into the curling wand.
In various exemplary embodiments, in addition to the electronic circuit device, the hair treatment system may have a data processing device or be configured to exchange data with the data processing device. The data processing device may be communication-enabled, i.e. have a data exchange device, for example part of a smart phone, a tablet, a laptop, a smart mirror or the like, on which an app may be installed, for example, or a cloud, for example, or the like.
In various exemplary embodiments, the hair straightener or the curling wand may have a data exchange device, for example for receiving hair condition parameters and/or environmental parameters detected by the sensor device, or to receive treatment parameters determined externally, and/or to receive recommendations and/or control commands determined by employing the data processing device.
By employing a software program, for example a (smart phone) app, information, for example control or regulation instructions, may be transferred to the hair treatment device (for example a “smart” hair straightener or curling wand), which may be configured, on the basis of the control or regulation commands, to control or regulate a hair treatment parameter, for example to dispense a hair treatment agent, to set a temperature at which the hair could be treated without further damage, etc. In this regard, an exchange of data may be cordless, for example via Bluetooth or a Near Field Communication technology (NFC technology).
In one exemplary embodiment, the at least one pump may be controlled or regulated by employing a smart phone or the like, for example by employing an app. The smart phone may form the data processing device, which receives sensor data from the sensor device and/or itself provides at least one condition sensor, for example the smart phone camera (optionally in connection with a suitable app for determining at least one hair condition parameter, for example a curliness of the hair, a hair colour or the like). With the aid of the at least one received and/or determined hair condition parameter (for example by employing suitable software, for example an app), a treatment parameter may be determined using the smart phone. As an example, using the smart phone, a flow rate for the hair treatment agent may be determined and, by transmitting a dispensing command from the smart phone to the hair treatment device, can be set in the hair straightener/curling wand.
In various exemplary embodiments, a hair treatment system may be provided which may have a hair treatment device (for example a hair straightener, a curling wand or the like), and furthermore may have a data connection (for the data exchange feature, the term “connectivity” is frequently employed) between an external app and the hair treatment device (for example the curling wand or the hair straightener). In various exemplary embodiments, care/styling parameters may be provided, for example specified (for example a maximum temperature), whereupon the parameters provided may be with respect to a degree of damage to the hair, i.e. the parameter may have a different value depending on the degree of damage to the hair.
In various exemplary embodiments, the input device may be configured to record at least one input by the user and to provide it to the electronic circuit device and/or to an external data processing device. Parameters or information to be input by the user may, for example, comprise age and/or gender, a desired hairstyle, an actual hair length, curliness of the hair or the like.
In various exemplary embodiments, one or more items of information be stored as part of a user profile, for example in the electronic circuit device and/or in the external data processing device, and therefore be able to be recalled for subsequent use.
In various exemplary embodiments, comparative images may be provided for the input, for example, from which the user can select (for example by tapping/clicking or the like) that which most closely resembles their current and/or desired condition (also termed the desired condition or target condition, and in the case of a hairstyle, the desired hairstyle). Instead of comparative images provided by the system or as a supplement thereto, an image may be provided to the system by the user, for example a digital image, on which a hairstyle of the user is depicted, and/or a digital image may be provided by the user, onto which a desired hairstyle of the user is overlaid, for example a prominent person, a friend of the user with the desired hairstyle, or a hairstyle model from a “Look Book”.
The information provided by the user, for example as regards their desired condition, may in various exemplary embodiments be taken into account by the electronic circuit device and/or the external data processing device during determination of the hair treatment, for example of the at least one hair treatment parameter.
In various exemplary embodiments, step-by-step instructions may be provided as to how the desired condition, for example the desired hairstyle, is to be obtained, taking into consideration the determined condition of the hair and/or environmental parameters and the information provided by the user. The instructions may, in various exemplary embodiments, be provided by employing the output device, for example as a sequence of images or video and/or as spoken instructions. As an example, the instructions may be provided in a manner such that the user can selected a required point in the sequence and/or in a manner such that completion of one of the steps in the instructions is automatically detected by the condition sensor and/or treatment sensor and/or is indicated by the user, and subsequently, the subsequent step of the instructions is provided.
The controlled or regulated element for controlling or regulating the hair treatment may have a dispensing device for the hair treatment agent and/or a heating device for heating the hair and/or a motor for exerting a force on the hair. The controlled or regulated element may, in various exemplary embodiments, be controlled by employing a wireless transmission device, for example wherein the application device receives control commands by employing the wireless transmission device. The wireless transmission device may, for example, be part of the electronic circuit device. In various exemplary embodiments, the wireless transmission device may have a chip or tag which permits wireless data transmission, for example by employing Bluetooth, WLAN, ZigBee, NFC, Wibree, Thread, WiMAX or the like.
In various exemplary embodiments, before providing a recommendation to the user, a data comparison may be undertaken between the smart terminal and/or the smart styling appliance and data, for example reference data which, for example, could be stored in a cloud. In various exemplary embodiments, the data may comprise data from other users which, for example, in turn comprise at least one hair condition parameter and, for example, corresponding derived recommendation/measures.
In various exemplary embodiments, the determined recommendation may be used to produce an optimized/personalized styling product, for example as an order for the production of an optimized/personalized styling product.
In various exemplary embodiments, a conventional hair treatment agent may be employed.
In various exemplary embodiments, a user input on an application device may be used for optimized dispensing of the styling product. With the aid of a digital display and a touch screen, the user can select the desired quantity of product. In this regard, a stored recommendation from experts may already be programmed into the appliance, for example filed (i.e. stored) in a database. By employing a previous individual input of the user's hair length, a (quantity and) product recommendation can then be generated. This can then be either confirmed, increased or reduced by the user if the user is already aware that they tend to use more/less product than is stated on the packaging as being normal.
In various exemplary embodiments, a method for the cosmetic treatment of hair is provided which enables correct selection of the product to be made, i.e. a selection which is suitable for the degree of damage to the hair. As an example, during the hair treatment, a product may be used for hair styling which is exactly appropriate to the degree of damage to the hair.

In this regard, in various exemplary embodiments, the signals captured by employing the sensors may be compared with signals stored in a database (also described as comparative signals, comparative data, reference signals or reference data). In various exemplary embodiments, with the aid of these, the degree of damage to the hair or another hair condition parameter may be classified, for example by assigning degrees of damage to the hair to the comparative signals, and the degree of damage to the hair or the other hair condition parameter of the comparative signal most similar to the measured signal is assigned to the measured hair.
The reference data which, for example, may be provided as a database, may in various exemplary embodiments be obtained empirically (for example in the laboratory) for hair for which the degree of damage to the hair is known. In various exemplary embodiments, furthermore, other information may be available regarding the hair which acts as a basis for the reference spectra, for example “hair bleached four times—high degree of damage” or “untreated hair—no damage”, and/or for hair which is used for the determination of the reference spectra, a development of a condition of the hair, for example the degree of damage to the hair, may be provided, for example a plurality of reference spectra, each of which being recorded after another hair treatment stage, wherein the hair treatment may comprise a caring hair treatment and/or a damaging hair treatment. An agent (for example product and/or ingredient) which is used for a treatment could also have been recorded in the database.
In various exemplary embodiments, the additional information may also be provided to the user (for example from the database), for example as to which level of treatment a condition of the hair corresponds, and/or how their condition of the hair will probably develop if they undertake a specific treatment, for example by using a specific agent.
In various exemplary embodiments, for example when a cloud is employed, the database may be produced using user data instead of being produced in the laboratory (and, for example, be continuously updated). In various exemplary embodiments, the database produced in the laboratory may be supplemented by employing user data which may be provided by employing the cloud.
In various exemplary embodiments, the displayed data, as described elsewhere herein, may be analysed by employing software algorithms in order to determine a hair condition parameter, for example a degree of damage to the hair, and/or an environmental parameter.
In various exemplary embodiments, for example when the reference data is provided by employing the cloud, these may be made available to the user at any time for use as reference data in a comparison.
In various exemplary embodiments, the data captured by employing the hair treatment device or by employing the hair treatment system may be stored, for example in a memory integrated into the hair treatment device and/or in the external data processing device, for example the cloud. The stored data may be stored in a manner such that at least the user is permitted to identify these data as their data. In this manner, a comparison of hair information obtained at different times, for example, (for example before and after a treatment) can be compared with each other.
In various exemplary embodiments, the hair treatment system may have a connection for transmitting (sending and/or receiving) data, for example between a smart phone/tablet which may be part of the hair treatment system, and a cloud, and/or between the hair treatment device and the smart phone/tablet, and/or between the hair treatment device and the cloud, and/or between the sensor device and the hair treatment device, and/or between the sensor device and the smart phone/tablet, and/or between the sensor device and the cloud.
In various exemplary embodiments, the analysis may be carried out by the hair treatment device, for example by employing the circuit device, and an analysis result may be transmitted in order to provide the result of the analysis on a display device, for example on a display, a speaker, a smart phone or the like.
In various exemplary embodiments, the data may be transmitted to/onto a data processing device, for example on a smart phone with an app, on a cloud, etc. After transmitting data to the data processing device, this can be used to interrogate the data, for example in order to determine a control or regulation parameter. In various exemplary embodiments, the data processing device may be part of the hair treatment system, for example in the case in which the data processing device, for example the smart phone or the like, is part of the sensor device and/or of the input and/or output device or a stand-alone part of the hair treatment system (also described as an integrated data processing device).
In various exemplary embodiments, the data processing device may be an external data processing device, for example the cloud.
In various exemplary embodiments, the control or regulation parameter or the recommendation may be or will be determined directly by employing the hair treatment system, for example the hair treatment device and/or the sensor device and/or the input or output device and/or the other integrated data processing device, i.e. the electronic circuit device and/or the integrated data processing device may be configured in a manner such as to determine the control/regulation parameter and optionally other information itself (also described as directly). As an example, the electronic circuit device may be or comprise a data processing device; as an example, it may be equipped with a memory and a processor, for example a microprocessor, which may be configured, for example by employing programming, to receive the sensor data and to control or regulate the hair treatment device and optionally provide the user with information.

FIGS. 1A, 1B and 1C and FIG. 2A to FIG. 2E respectively show a diagrammatic view of a hair treatment system 200 in accordance with various exemplary embodiments, wherein different exemplary embodiments are identified by supplemental lower case letters.
FIGS. 3A and 3B respectively show a diagrammatic view of an applying a hair treatment system 200 in accordance with various exemplary embodiments.
In various exemplary embodiments, the hair treatment system 200 comprises a hair treatment device 100 (various exemplary embodiments identified by 100 a, 100 b, etc).
Even though in the figures, the hair treatment device 100 is shown diagrammatically as a hair straightener (FIG. 1A, 1B, 2A to 2F) or as a curling wand (FIG. 1C), it should be understood that the respective exemplary embodiment may also be embodied as the other type of hair treatment device or a similar hair treatment device (which is provided to carry out mechanical work on the hair and to heat the hair thereby, in order to implement a semi-permanent shaping of the hair), unless the context dictates otherwise.
The hair treatment device 100 may comprise a device body 100K. The device body 100K may be formed from a solid material, for example plastic or metal, or may comprise such a material. As an example, the device body 100K may be formed from a material or comprise a material which is usually employed for a hair straightener or a curling wand.
In various exemplary embodiments, the hair treatment device 100 may furthermore comprise a controllable or regulatable heating device 122 (shown only in FIG. 1C, otherwise hidden inside the hair treatment device 100), which may, for example, be integrated into the device body 100K.
In various exemplary embodiments, the hair treatment system 200 may comprise a sensor device 114 with at least one sensor 106 in order to capture at least one hair condition parameter and/or at least one environmental parameter. The at least one sensor 106 may comprise one or more of the sensors 106 described above and/or other/further sensors 106.
As discussed above, the at least one hair condition parameter may, for example, be a hair moisture, a degree of damage to the hair, a hair thickness, a hair density, a curliness or the like. As discussed above, the environmental parameter may comprise, for example, a humidity of the air, a temperature, a wind strength or the like.
In various exemplary embodiments, the at least one sensor 106 may be configured to capture more than one parameter; as an example, the sensor 106 may comprise a NIR spectrometer which may be configured to capture both parameters for the determination of the hair moisture as well as parameters for the determination of the degree of damage to the hair, and/or the sensor 106 may comprise a camera which (for example by employing software) may be configured to determine parameters for determining curliness.
In various exemplary embodiments, as can be seen in FIGS. 1A to 1C and 2A to 2C, the sensor 106 may be disposed in the device body 100K, for example housed and sealed therein. This means that the hair treatment device 100 is resistant to moisture (in particular also to moisture in the hair treatment agent to be applied) and to dirt.
Further, the sealing means that the hair treatment device can be cleaned without damaging the sensor 106 or any other device. As an example, the sensor 106 could be injection moulded at the same time as the device body 100K.
In various exemplary embodiments, for example when the at least one sensor 106 comprises or consists of an optical sensor, the device body 100K may be transparent between the sensor 106 and a surface of the device body 100K. In various exemplary embodiments, as long as it is appropriate, the sensor 106 may be disposed in the device body 100 in a manner such that it faces the hair 220H of the user 220 when the hair is in its usual arrangement on or in the hair treatment device 100, or is in contact with the hair 220H.
In various exemplary embodiments, as can be seen in FIGS. 1A to 1C and 2A to 2C, the sensor 106 may be disposed in the device body 100K.
In various exemplary embodiments, as can be seen in FIGS. 2D to 2F, the sensor 106 might not be integrated into the hair treatment device 100, but be a part of a separate sensor device 114. As can be seen in FIGS. 2D and 2E, in various exemplary embodiments the separate sensor device 114 may alone serve to capture, optionally process and transmit the captured and/or processed data.
In various exemplary embodiments, the sensor device 114 may also fulfil at least one further function, i.e. as can be seen in FIG. 2F, the sensor device 114 may be integrated with a further device of the system, for example with an input and/or output device. In FIG. 2F, as an example, a smart phone may be used as a sensor, for example by employing its camera, and its touch screen may be used as the input and output device. Furthermore, the electronic circuit device of the smart phone, which may comprise a processor and a memory, may be configured to undertake an evaluation of the recorded data (for example images) and, for example, from an image that shows the hair 220H of the user 220, may determine the curliness of the hair or the like. The determined hair condition parameter may be transmitted to the hair treatment device for controlling or regulating the hair treatment device.
The external sensor device 114 may comprise an electronic circuit device 1040 and a cordless data exchange device 1040 a which may be similar to or identical to the electronic circuit device 104 and the cordless data exchange device 104 a from the previous exemplary embodiments.

In various exemplary embodiments, the electronic circuit device 104 may be coupled to at least one sensor 106, for example by employing a connection 108, in order to receive the captured sensor value. When a plurality of sensors 106 are present, the electronic circuit device 104 may comprise a unique coupling to each of the sensors 106. In various exemplary embodiments, the coupling may comprise or be an electrically conductive connection, a (glass) fibre connection and/or a cordless connection. The electronic circuit device 104 may be configured to receive the at least one sensor value from the at least one sensor 106.
In various exemplary embodiments, the electronic circuit device 104 may be or comprise a data processing device; as an example, it may be equipped with a memory and a processor, for example a microprocessor, which may be configured, for example by employing programming, to receive data from the sensor 106 and from it to derive one or more hair treatment parameters in order to control or regulate the hair treatment device, for example as described above by controlling or regulating a temperature of the hair straightener/curling wand, a force exerted on the hair 220H of the user 220 (for example in the form of a pressure with which two parts of a two-part hair treatment device, as can be seen in all of the exemplary embodiments from FIGS. 1A to 1C, 2A to 2F, 3A and 3B, are pressed together), and/or dispensing of a hair treatment agent.
In various exemplary embodiments, each of the thermal/mechanical elements of the hair treatment device may be or will be controlled or regulated by employing an actuator 110.
As an example, the heating device 122 may comprise, as the actuator 110, a temperature control/regulator, the exertion of force on the hair may be carried out by employing a controllable/regulatable motor as the actuator 110, and/or the application device (nozzles 120 of the application device are shown in FIG. 1B) for the hair treatment agent may comprise a pump and/or a dispensing valve as the actuator 110. The actuator 110 may be configured in a manner such that it can influence a hair treatment parameter. The actuator 110 may respectively be controlled or regulated or be controllable or regulatable in a manner such that the hair treatment parameter which is influenced by the actuator 110 corresponds to the hair treatment parameter determined by employing the hair condition parameter and/or the environmental parameter.
In various exemplary embodiments, the electronic circuit device 104 may be configured, based on the data received from the sensor 106, to determine at least one recommendation and to provide it to the user 220, for example (as described above) as an instructional video, as a product recommendation for a known hair treatment agent or as a formula for an individual hair treatment agent, as described above.
In various exemplary embodiments, for example in the case in which the at least one sensor 106 is used in order to determine a degree of damage to the hair, a curliness or the like, the hair treatment device 100 may be configured to control the actuator 110, for example to set a temperature for the hair treatment, for example a straightening procedure or a curling procedure, which is suited to the degree of damage to the hair, the curliness or the like.
In various exemplary embodiments, for example in the case in which the at least one sensor furthermore comprises at least one treatment sensor 128, for example temperature sensors 128, in order to determine a hair temperature, for example at positions in front of and behind the heating device, the hair treatment device 100 may be configured in a manner such as to regulate the actuator 110, for example to set a temperature for the hair treatment, for example a straightening procedure or a curling procedure, which is suited to the degree of damage to the hair, the curliness or the like and on the basis of the temperature captured by employing the treatment sensors 128 (in particular the temperature behind the heating device, i.e. after the heating treatment), to readjust it. Other possible types of treatment sensors 128 have been described above.
In various exemplary embodiments, the hair treatment device 100 may be configured to regulate the actuator 110 solely on the basis of temperature sensor data.
In various exemplary embodiments, the actuator 110 may be configured to be set at a relatively high temperature, for example in the range from approximately 200° C. to approximately 230° C., when it is determined that the hair 220H of the user 220 is undamaged and/or thick, for example, and to be set at a relatively low temperature, for example in the range from approximately 150° C. to approximately 180° C., when it is determined that the hair 220H of the user 220 has already been damaged and/or is fine, for example.
In various exemplary embodiments, the user 220 may also be provided with a hair treatment recommendation; as an example, in the case of the hair straightener or curling wand, a recommendation “treat each strand of hair for a maximum of five seconds” or the like may be provided.
In various exemplary embodiments, as can be seen in FIG. 1B, the actuator 110, for example as an alternative to or in addition to temperature control or regulation, may comprise the controllable or regulatable application device (also termed the dispensing device), which is configured to dispense the hair treatment agent on the basis of the captured sensor data.
As discussed above, the application device may comprise at least one pump and/or at least one valve, which may be controllable or regulatable in a manner such that a volume or a quantity of the hair treatment agent can be dispensed. Dispensing may in various exemplary embodiments be carried out as a function of a position of the hair treatment device 100 on the hair 220H; as an example, when it is determined that the hair treatment device 100 is located at the roots of the hair, a different quantity of hair treatment agent may be dispensed than when it is determined that the hair treatment device 100 is positioned at the tips of the hair. As an example, the tips of the hair may require a larger quantity of hair care agent than the roots.
As can be seen in FIG. 1B, in various exemplary embodiments, the hair treatment agent may be accommodated or will be accommodated in the hair treatment device 100 in a cartridge 130. The cartridge 130 may be refillable, for example.
