Computer-Aided Hair Coloring Agent Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hair coloring methods limit the determination of a desired hair color to pre-defined combinations, failing to accurately match the expected and achieved results due to limited options for initial hair states, such as base color, graying, and damage levels.
Innovation Solution
A computer-aided method using predictive analytics to determine the optimal hair coloring agent by analyzing initial hair states and achievable colors based on a relationship between coloring pre-condition parameters and achieved hair colors, allowing for precise calculation of color properties like shade, intensity, and brightness, and selecting the appropriate hair coloring agent to achieve the desired hair color.

1Ease of operation
If conventional pre-defined combinations of initial hair state values are used, then the device complexity is reduced and ease of operation is improved, but the manufacturing precision and reliability of color matching deteriorate
Solution Approach 1:
The patent transforms the discrete, pre-defined parameter values into continuous measurement parameters. Instead of selecting from fixed categories like 'blond', 'medium-blond', 'brown' for base hair color, the system uses optical measurement devices to capture precise colorimetric data (L*a*b* values, reflectance spectra) of the actual hair. Similarly, graying and damage levels are quantified through specific measurement parameters rather than rough estimates. This parameter transformation enables precise calculation of achievable hair colors based on the actual measured initial state.
Solution Approach 2:
The patent replaces the manual, experience-based mechanical selection process with an automated optical measurement and calculation system. Optical measurement devices (spectrophotometers, colorimeters) substitute for visual assessment by technicians. Computer algorithms substitute for expert knowledge and experience in predicting coloring results. This substitution of mechanical/optical measurement and computational systems eliminates human subjectivity and achieves consistent, precise color matching.
2Device complexity
If conventional pre-defined combinations are used, then the device complexity is reduced, but the measurement precision and adaptability to individual hair states deteriorate
Solution Approach 1:
The patent replaces simple selection interfaces with automated optical measurement devices that precisely quantify hair properties. Spectrophotometers measure reflectance spectra across multiple wavelengths to determine exact color values. Specialized measurements detect graying levels by analyzing specific spectral characteristics and damage levels through surface property analysis. These optical measurement systems provide objective, precise data without requiring complex user judgment or multiple device components.
Solution Approach 2:
The measurement system is designed to automatically perform multiple assessments without requiring separate devices or complex user operations. A single optical measurement device simultaneously captures base color, graying level, and damage state through integrated measurement routines. The system self-calibrates and processes measurements automatically, reducing the need for multiple specialized tools while maintaining high measurement precision across all parameters.
3Ease of operation
If pre-defined value combinations are used, then the ease of operation is improved, but the adaptability to individual customer hair states deteriorates
Solution Approach 1:
The system accepts any measured parameter values as input, transforming the fixed combinatorial approach into a continuous parameter space. The calculation algorithm works with precise measured values of base color (L*a*b*), graying percentage, and damage level to predict achievable colors. This parameter continuity allows the system to adapt to any individual hair state within the measurement range, not just pre-defined categories.
Solution Approach 2:
The patent implements a dynamic calculation system that adapts predictions to the specific measured initial state. Rather than static lookup tables for pre-defined combinations, the system dynamically calculates achievable hair colors based on the actual measured parameters. The algorithm adjusts predictions according to the specific interaction between the measured initial state and the coloring agent properties, enabling real-time adaptation to individual customer hair characteristics.
