Apparatus and method for analyzing hair and/or predicting an outcome of a hair-coloring treatment

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. 本发明涉及用于分析毛发和/或预测毛发染色处理的结果的方法与装置。本发明公开的是在毛发样品上预测毛发颜色改变处理的结果的方法，该方法包括：a.对于多个区别区域的每
