Beschreibung
Zusammenfassung:	An apparatus and method for customized hair-coloring is disclosed. In some embodiments the method comprises: a. performing a plurality of light-scattering measurements upon a sample of hair such that for each light-scattering measurement, the sample of hair is illuminated from a different respective direction; b. comparing the results of the light-scattering measurements; c. in accordance with results of the comparing, computing an initial damage-state of hair of the sample by comparing the results of the light-scattering measurements; d. obtaining an initial color-state of the hair of the sample; and e. computing a hair-coloring composition that is predicted to transform the hair sample from the initial color-state to a target color-state such that in response to a determining of a greater (lesser) extent of initial damage, a concentration of artificial-colorant(s) within the computed coloring composition is reduced (increased).
