Disclosed is a method with different exemplary embodiments for determining a degree of damage to hair. Said method can comprise the following steps: during the exposure of a hair sample to near-infrared and/or infrared light, recording a spectrum of at least part of the near-infrared and/or infrared light that has interacted with the hair sample, comparing at least part of the spectrum with a spectroscopic calibration model obtained by near-infrared and/or infrared spectra and degrees of damage of a plurality of calibration hair samples, and determining the degree of damage to the hair using said comparison.

Method and device for determining a degree of damage of hair, and method for determining a user-specific hair treatment agent

The present disclosure relates to a method for determining a user-specific hair treatment with determination and inclusion of the state of the hair. To this end, the content of at least one hair constituent is firstly determined with the aid of near-infrared and/or infrared and/or VIS and/or Raman spectra of the hair of an individual and a hair state is derived via a calibration model. Individual treatment advice is output on the basis of the determined hair state.

System and method for establishing a user-specific hair treatment

In various embodiments, a method of providing a hair treatment agent is provided. The method can have a detecting of at least one sensor value on hair of a user by employing at least one portable sensor, a determining of a hair condition of the user by employing the detected at least one sensor value, a computer-assisted determining of a user-specific hair treatment agent including the determined hair condition, and a preparing of the determined user-specific hair treatment agent by employing a hair treatment agent mixing device.

Method and device for providing a hair treatment agent

In various embodiments, a method for determining a homogeneity of complexion is provided. The method may include provision of a digital image on which skin is portrayed and which is parameterized in a color space which is defined by a parameter set in which one of the parameters is a hue, identifying and/or defining at least one skin examination area in the transformed image, calculating a hue distribution in the at least one skin examination area, and determining at least one homogeneity value for the complexion based on the calculated hue distribution.

Method and device for determining the homogeneity of skin color

The present disclosure relates to a method for determining a user-specific hair treatment with determination and inclusion of the degree of damage of the hair. To this end, the content of cysteic acid is firstly determined with the aid of near-infrared and/or infrared spectra of the keratin fibres of an individual and a degree of damage is derived via a calibration model. Individual treatment advice is output on the basis of the determined degree of damage.

Method for determining a user-specific hair treatment

A method for determining a user-specific hair treatment by determining and inclusion of the degree of damage of hair is provided. To this end, initially, with the aid of near-infrared and/or infrared spectra of the keratin fibres of an individual, the amino acid oxidation product content is determined and a degree of damage is derived from it via a calibration model. Individual treatment advice that is based on the determined degree of damage is issued.

A method and data processing device is described herein for computer-aided determination of a hair coloring agent for coloring of hair in a desired hair color. A device for production of an individually determined hair coloring agent is also described herein.

Method and data processing device for the computer-assisted determination of a hair dyeing agent for dyeing hair in a desired hair color and device for producing an individually determined hair dyeing agent

In various exemplary embodiments, a method for computer-supported determination of properties of hair colors is prepared. The method can include: preparing hair color data, wherein the hair color data has values for a multitude of color pre-condition parameters and for at least one coloring result parameter for a multitude of coloring processes, wherein the multitude of coloring processes includes a first concentration of a first dye precursor and a second concentration of a second dye precursor for each coloring process of the multitude of coloring pre-condition parameters, wherein the multitude of coloring processes of the at least one coloring result parameters has a measured specification with a property of hair colors and determining a relationship between the multitude of coloring pre-condition parameters and the at least one coloring result parameter by employing predictive analytics based on the hair color data.

Method and data processing device for ascertaining properties of hair colors in a computer-assisted manner

Devices and methods for determining the thickness of hair are provided. An exemplary device includes a computing unit with a processor and a local memory. The processor is connected to the local memory and configured to read data from and/or to write data into the local memory. The device further includes a user input/output unit configured for interaction with a user. Also, the computing unit includes an image data input interface for receiving image data of at least one individual hair. The image data input interface is connected to the processor. Further, the computing unit includes a user interface connected to the user input/output unit and to the processor. The computing unit is configured to process the image data of the at least one individual hair to create hair thickness values of the at least one individual hair and to output the hair thickness values to the user interface.

Determining the thickness of hair on the head in a damage-free way

A method for determining a degree of damage to hair is provided in the form of various embodiments. Said method can comprise the following steps: during the exposure of a hair sample to UV light (for example by employing a UV-LED), detecting fluorescence light emitted by the hair sample, determining a fluorescence intensity by employing the detected light, and determining the degree of damage to the hair using said fluorescence intensity.

Method and device for determining a degree of damage to hair

A method and device for determining the color homogeneity of hair is provided. In accordance with various exemplary embodiments, a method comprises providing a digital image in which hair is depicted and which is parameterized in a color space which is defined by employing a parameter set in which one of the parameters is a hue, defining at least one hair analysis region in the digital image, determining a hue distribution in at least one hair analysis region, and determining at least one color homogeneity value on the basis of the determined hue distribution.
