Abstract
The present disclosure relates to devices and methods for analyzing hair and/or predicting an outcome of hair-coloring treatment. disclosed is method of predicting a result of a hair-color-modifying treatment on a sample of hair, the method comprising: a. for each given region of a plurality of distinct regions, respectively measuring a region-specific spectrum of respective material of the hair-sample respectively disposed within the given region; and b. computing first and second predicted post-treatment spectra respectively from first and second initial spectra by respectively predicting a transformation of the first and second initial spectra following subjecting the sample of hair to the hair-color-modifying treatment, the first and second initial spectra being distinct and (i) derived from the plurality of measured region-specific spectra and/or (ii) corresponding to first and second of the measured region-specific spectra.
