Abstract:
The present disclosure relates to hair readers, dispenser devices, and related systems and methods. For example the present aaplication relates to a method of optically acquiring data from keratinous fibers, the method comprising: a. illuminating the keratinous fibers such that light reflected and/or deflected and/or transmitted by the fibers is incident upon a detector and converted into electrical signals by the detector; and b. computing, from electrical signals, a plurality of spectra of the keratinous fibers such that each spectrum of the plurality of spectra respectively corresponds to (i) a different respective portion of the keratinous fibers and/or (ii) material within a different sub-region of space within which at least a portion of the keratinous fibers are disposed.

Abstract:
A system for preparing a hair-coloring composition comprising: a. a plurality of containers including first and second containers; b. a plurality of tablets disposed within each of the containers, each tablet comprising at least one of (i) permanent hair-coloring dye precursor and (ii) permanent hair-coloring dye coupler such that, a majority (e.g. at least a substantial majority) of the tablets in the first container comprise permanent hair-coloring dye precursor and are substantially free of permanent hair-coloring dye coupler, a majority of the tablets in the second container comprise permanent hair-coloring dye coupler and are substantially free of permanent hair-coloring dye precursor; c. a dispenser configured to dispense the tablets so as to provide multi-container tablet combinations comprising tablets from the first and second containers.Preferably, the dispenser is configured to dispense the multi-container combinations in accordance with at least one of (i) a hair coloring target and/or (ii) hair spectroscopy data.
