Description

COLOR CONSULTATION SYSTEM FOR A HAIR SALON

The subject matter of the application pertains to a system for recognizing an existing hair color, consultation with a customer, manufacturing a hair color treatment and use of the hair color treatment with the goal of producing a temporary or permanent hair coloring.

It is known to apply wash-out or permanent hair color to a human head of hair in order to temporarily or permanently realize a desired color. The hair color can be provided with or without the use of peroxide. It can be prepared in cream, gel, cream gel or liquid form.

Aside from being performed through visual recognition, an existing hair color of a customer can also be recognized by means of measurement technology. US 2004/0000015 Al discloses a technique for the measurement of hair color. An optical reflectance spectrum within the visible frequency range is thereby measured. The spectrum is then analyzed. Finally, an attainable hair color is displayed by means of a hair color spectrum, whereby a bleaching process can be considered or scheduled. The hair color treatment can then be prepared and mixed with regard to its components. Similar systems are known from publications US 2006/0195300 Al, US
7,110,117 B2, US 7,304,739 B2 and US 2007/0159290 Al, WO 2006/134429 A2 and US
6,490,492 B 1.

The publications US 6,330,341 B 1 and WO 96/41139, which describe among other things how measured colors can be recorded in tabular fashion and used for the manufacturing of hair color treatments, also disclose a measurement of reflectance spectrums of visible light falling on hair.
In principle, the data thus measured or generated can be transferred via wires or wirelessly by means of a transmitter in order to provide for their usage on a computer screen, (for example for a color or image simulation), a Palm, for a color mixing device, a user interface, a printer, a color table, a customer consultation system or a sales software. Corresponding technologies are known from EP 1817976 A1, US 2005/0036677 A1, US 7,006,657 B2 and EP 1147722 B1.
The known systems have the disadvantage that they are always restricted and therefore not universally applicable.

The object is thus based on removing these disadvantages.

The object is achieved according to claim 1. A color consultation system for a hair salon is thereby proposed. With this color consultation system, an existing color of human hair can be recognized and a hair color treatment can be prepared in order to change the color of the hair.
The color consultation system consists of:
- a measuring device for recognition of hair color - a unit for receiving the data from the measuring device - a device for input of at least one color parameter - a display unit for display of a measurement parameter or a color parameter - a processor for calculation of the components of a desired color for the hair, as well as - an output device for output or display of the components.

The proposed color consultation system has the advantage of being universally applicable. A
hair color can thus be recognized by means of a measuring device. The visual ability of the hairdresser or a technical measuring device is suitable in that regard. Data of the hair color are then fed into a device for receiving the data. In addition to this, a device for input is supplied with at least one color parameter in order to attain the desired hair color. A
processor calculates the necessary components of the desired color and an output device indicates the components.
The proposed color consultation system can be expanded with a series of useful devices.
Advantageous embodiments of the proposed hair consultation system are described in claims 2 to 35.

A hair color treatment can be manufactured in a simple manner when a mixing device is provided for mixing the hair color treatment or for preparation of the hair color components according to claim 2. It is thereby advantageous if the hair color can be selected from an assortment with multiple hair colors or multiple color components (claim 3).
The hair color treatments or color components can then be prepared in cream, gel, cr~me gel or liquid form (claim 4). In addition, a container of peroxide for preparation of the hair color treatment can be provided (claim 5).

A manually graspable measuring device which can be set on the hair or held up to it is suitable as a mobile unit for measuring the visible spectral range of light reflected from the hair, particularly that emitted from the device (claim 6), in order to measure the existing color of the hair. The measuring device can thereby transmit at least one parameter of the hair color measurement to the processor via a cable, or wirelessly according to claim 7 by means of a transmission-and-reception system (claim 7). Algorithms for processing the measured values are known from the corresponding publications.

As an alternative to measuring the hair directly and directly at the customer, the subject of claim 8 presents the possibility that the color consultation system is provided [sic] for removal of an end of a strand of hair and for detection of the hair color at a measuring device connected to the processor. According to claim 9, it is sufficient if either a portion of the spectral range which preferably has wavelengths of 400 to 800nm or the entire spectral range is provided for measurement. For better processing of the data, it is advantageous if the unit for receiving the data from the measuring device possesses a storage and preferably an additional processor (claim 10).

The display unit can consist of one screen or two screens for display of a respective hair color (claim 11). The components to be combined for a desired color treatment to be manufactured can be printed out by a printer or displayed by a display or screen according to claim 12.

The measurement values and/or the components of a desired color can be compared to each other by means of a mathematical algorithm or using a collection of index cards (claim 13). For better handling of the index cards, these can be placed in a receptacle or on a carousel (claim 14) so that they can be examined one after another in a simpler manner.

A mixing device can have a plurality of individual containers for holding different hair color treatments or components (claim 15) and respectively dispense from these containers a partial quantity (for example in liquid or cream form) in order to prepare a mixture of different color components or to mix these, in particular using a peroxide solution. A simple execution is thereby achieved if, according to claim 16, one valve per container is provided for opening and closing a downward facing outlet of the container, a control device is provided for operation of the valves, and there is a collection unit underneath the containers for outputting the dispensed product through an outlet into a vessel.

In further advantageous embodiments the color consultation system can possess a keyboard which serves for the input of data into the processor (claim 17) and a portable pocket computer with a screen and with input keys can be part of the consultation system (claim 18).

In order to better compare a previous color situation with a subsequent color situation, or in order to better compare two color results (claim 20) with each other, it is proposed that a screen be divided into two screen partitions on which different displays of colors can be depicted, or that two separate screens are provided per display device (claim 19). An even greater amount of color information is achieved if a plurality of screen partitions or screens is provided according to claim 21. A good observation of a selected picture and a possibility of introducing more alternatives are thereby achieved if, according to claim 22, a larger screen is provided for the display of a representation of a customer request or an output situation and a series of smaller screens are provided for the display of alternatives.

Data regarding color treatments, color components or hair colors can be saved and recalled if the screen or processor has a connection for a USB stick (claim 23) in order to transfer these data to or from the processor.

A mixing device could have a series of containers with a respective piston for emptying the container (claim 24). In the case of a liquid hair color treatment or given use of creams as components for preparation of a hair color treatment, the components can also be dispensed flowing freely downwards.

A scale (claim 26) and a brush, coloring comb or color applicator (claim 25) are reasonable utensils for weighing and applying the color treatment product.

According to claim 27, it is advantageous if a processor of the color consultation system is connected via an Internet connection to a database for hair color treatments or colors of hair.
Data of customers and in relation to hair colors or color trends can then be accessed over the Internet and used in a hair salon.

Catalog systems are suitable for input or selection of data. In this case or in general, an input or selection of data can be performed by means of a touch screen, a mouse (claim 28) or speech recognition.

A program for supporting or for operation of the color consultation system can be provided for use on the part of an end user or a hairdresser (claim 29, claim 30), or it can be designed for both (claim 31).

The program can present pictures (for example with particular colors or hairstyles for a picture or a video sequence of the customer or another person) for selection and query with regard to a desired color. It can also be possible to make a selection according to pictures or according to words (claim 33), to display a selection as well as options for this selection, for example different color tones (claim 34), or to recommend a color and a product for hair coloring (claim 35) depending on the type and data of a customer.

In the following the proposed color consultation system is described in detail using Figures representing exemplary embodiments. They show:
Figure 1 a color consultation system with a spectral measuring device for recognizing a hair color, a screen as a display unit for display of measurement and color parameters, a computer for calculation of the components of a desired color for the hair under consideration of wirelessly transmitted measurement data, and a printer for the output of matching hairstyle trends and trend colors;

In a color consultation system for a hair salon with which an existing color of human hair can be recognized and a hair color can be prepared in order to change the color of the hair, a measuring device 1 serves for detection of the hair color and as a unit 2 for receiving the data of the measuring device 1 via a device 3 for input of at least one color parameter [sic]; a display unit 4 serves to display a measurement parameter or a color parameter; and a processor 5 serves for calculation of components of a desired color for the hair, [sic] it is possible to operate an output unit 6 for output or display of the components in order to then display the composition of a hair color treatment after the recognition of a preexisting color of hair. Finally, a mixing device 7 serves to manufacture the necessary hair color treatment. In this multiple color components 9 can be selected and prepared from an assortment 8 of several base color components. The color components 9 can thus be available in liquid form 10 and can be combined with peroxide 12 as a mixture.

The measuring device 1 has a mobile unit for measuring the visible spectral range of the light reflected from the hair and transmits parameters of the hair color measurement to the processor 5 by means of a transmitter system 13 and a receiver system 14. A section of the spectrum of the wavelength range reflected from the hair from 400 to 800 nm is thereby measured and sent to the receiver system 14.

The unit 2 for receiving data can use the storage 16 of an additional processor 17 (which is designed as a hand-held device in the type and manner of a manually operated color computer) in order to utilize an additional color consultation.

In a further exemplary embodiment, the display unit 4 can have two screens 18, 19 in order to show two possible color results, and a collection 22 of index cards 23 can be provided in a receptacle 24 or on a carousel 25 in order to serve for a color consultation.

A mixing device 7 has a plurality of individual containers filled with different base color components in liquid form. A valve 27 for opening and closing a downward facing outlet of the container 26 is provided per container 26 [sic]. A control device 28 is provided for operation of the valve 27. A collection unit 28 underneath the container 26 serves to output the dispensed product through an outlet 29 into a vessel 30.

Data or customer requests can be input by means of a keyboard 31 into the processor 5. A
similar process is possible in a pocket computer 32 by means of input keys 33.

For a better overview of possible color results, a screen partition 34 or a screen can respectively be used for the display of an actual or desired state, whereby different hairstyles and/or different color results are displayed. It is advantageous to provide a plurality of screen partitions 34 or screens 18 for a large selection. A particularly clear arrangement is depicted by a centrally aligned, somewhat larger screen 12 for display of a representation of a customer request or an output situation and a series of smaller screens 18 around the periphery for display of alternatives to the central picture.

External data can be used by the color consultation system if these are supplied via a connection 35 from a USB memory stick 36. Data of the color consultation system can also be transferred in the reverse direction. This handling of data is also possible in similar ways over an Internet connection 41.

If containers 26 with respective pistons 37 for emptying the containers 26 are installed in a mixing device 7, paste or cream type color components can be discharged. A
reactive hair color can then be applied to the hair by means of a brush 38 after the color components have been set on a scale 39 with a product receptacle 40 with peroxide.

Data or selection criteria can be input with a mouse 42. The corresponding programs can be designed for the end user and/or the hairdresser.

The following methods and apparatus can be used:

a) A color measuring instrument for use in identifying a particular classification from a table and a database that identifies appropriate coloring agents based on a selection of coloring actions from a menu and the classifications of hair color.
b) A system for determining hair color treatment, including a processor. The processor is configured for: receiving as input an initial spectrum of a sample of hair, the initial spectrum having a wavelength range; calculating a new spectrum of the hair due to a hypothetical hair color treatment as a direct function of the initial spectrum; and outputting data to a device, the data being based upon the step of calculating.

d) A method to change the color of hair which includes measuring an initial reflectance spectrum of a sample of the hair and analyzing a contribution of a plurality of natural hair factors to the initial reflectance spectrum. The method also includes calculating a hair treatment based on another reflectance spectrum. A system to measure a reflectance spectrum of a sample includes an integrating sphere having a sampling port and an inner surface and a window disposed near to the sampling port. The window is configured for being placed in close contact with the sample. The system also includes a light source configured to project light onto the sample via the window and a light detector configured to analyze light reflected from the inner surface to produce the reflectance spectrum of the sample. e) An apparatus for analyzing a sample hair mixture having a mixture of two hair colors and an overall spectrum representative of the two colors, comprising: a first color selector, configured to select a first spectrum representative of a first color in the hair mixture from a first group of at least one spectrum, and an iterative spectrum combiner, associated with the first color selector and configured to iteratively combine therewith a second spectrum representative of a second color in the hair mixture from a second group of spectra over the first spectrum, thereby to find an optimal combination of first and second spectrum which is a closest match to the overall spectrum. And f) a hair color analysis process comprising the steps of measuring with a measuring instrument the value of a plurality of color factors in the color of an individual's hair, providing an indicator having a plurality of hair color classifications defining ranges of said color factors, and comparing the plurality of color factors to the ranges of the color factors, to indicate a classification of hair color.

The relative proportions of amylose and of amylopectin, and also their degree of polymerization, may vary as a function of the botanical origin of the starches. The botanical origin of the starch molecules used may be cereals or tubers. Thus, the starches may be, for example, chosen from corn starch, rice starch, cassaya starch, tapioca starch, barley starch, potato starch, wheat starch, sorghum starch and pea starch. Starches are generally in the form of a white powder, which is insoluble in cold water and which has an elementary particle size ranging from 3 to 100 microns.
The starches may optionally be C 1-C6 hydroxyalkylated or C 1-C6 acylated (such as acetylated).
The starches may also have undergone heat treatments. Distarch phosphates or of compounds rich in distarch phosphate, for instance the products sold under the references Prejel VA-70-T
AGGL (gelatinized hydroxypropylated cassaya distarch phosphate) or Prejel TKI
(gelatinized cassaya distarch phosphate) or Prejel 200 (gelatinized acetylated cassaya distarch phosphate) by the company Avebe, or Structure ZEA from National Starch (hydroxypropylated corn distarch phosphate), Structure XL from National Starch (hydroxypropylated starch phosphate) may also be used.
The guar gums may be modified or unmodified. The unmodified guar gums are, for example, the products sold under the name Vidogum GH 175 by the company Unipectine and under the names Meyro-Guar 50 and Jaguar C by the company Meyhall. The modified nonionic guar gums are, for example, modified with C1-C6 hydroxyalkyl groups. Among hydroxyalkyl groups, mention may be made, for example, of hydroxymethyl, hydroxyethyl, hydroxypropyl and hydroxybutyl groups. These guar gums are well known in the state of the art and may be prepared, for example, by reacting corresponding alkene oxides, such aspropylene oxides, with guar gum so as to obtain a guar gum modified with hydroxypropyl groups. The degree of hydroxyalkylation, which corresponds to the number of alkylene oxide molecules consumed by the number of free hydroxyl functions present on the guar gum, may, for example, range from 0.4 to 1.2.
Such nonionic guar gums optionally modified with hydroxyalkyl groups are sold, for example, under the trade names Jaguar HP8, Jaguar HP60 and Jaguar HP 120, Jaguar DC 293 and Jaguar HP 105 by the company Rhodia Chimie (Meyhall) or under the name Galactasol 4H4FD2 by the company Aqualon.

(vii) The C12 - C30 fatty alcohols are, for example, chosen from myristyl alcohol, cetyl alcohol, stearyl alcohol, behenyl alcohol or mixture thereof. When fatty alcohols are used as thickeners, at least one additional surfactant with HLB value above about 6 is commonly included to form bi-layers with fatty alcohols. The most useful bi-layer structures include gel network phase where parallel bi-layers of fatty alcohols are swollen by water forming semi-solid creams, and vesicle dispersions where fatty alcohols bi-layers are curved into approximately spherical uni-lamellar or multi-lamellar aggregates.
(viii) The particulate and crystalline thickeners are for example, clays, fumed silica, microcrystalline cellulose, trihydroxystearin (ThixcinR), ethyleneglycol mono-and di-stearate or mixture thereof. The particulate or crystalline thickeners work via mechanisms well known in the art, for example particle aggregation, "house of card" particle arrrangement or crystalline fiber formation.

In addition the dye compositions can be thickend by adding prior to use anionic acrylic polymers as described in WO 01 /97772, which are sold by Arch Personal Care Products, South Plainfield, USA under the tradename ViscUp EZ.
