  • Method for determining parameters specific to the custom-made coloring of the hairs of a given individual
    Patent number: 12446679
    Abstract: The present invention relates to a method for determining a parameter specific to the custom-made coloring of hairs of a given individual, the method including the following steps: receiving magnitudes representative of a first target color and of a first initial color in a colorimetric space, determining a cosmetic product composition according to magnitudes received and a colorimetric rendering model, applying a cosmetic product having the determined composition on the hairs to be colored of the individual in order to obtain colored hairs, evaluating the color of the colored hairs in order to a magnitude representative of a first final color in the colorimetric space, and determining a colorimetric deviation parameter specific to the individual according to magnitudes representative of the first final color and of the first target color.
