Microspectrophotometry was used to characterize dyed and bleached human hair fibers. The identification of dyed hair is important when investigating a crime scene. If bleaching or dyeing has artificially altered hairs, their evidential significance will increase. Microscopic techniques allow the analyst to examine and compare hair's structural characteristics but are rather limited for similar color comparison. Color is an important feature in hair dye analysis because it helps in reaching conclusions about similarities and differences.

520 $a This research proposed to determine how much dye is required for the visible spectrum of one strand of hair to become consistent with that dye and to compare the microspectra of bleached hair fibers. The results of the hair dyeing analysis determined that the even distribution of the dye varied with each brand name. The results of the hair bleaching analysis demonstrated that there are no significant spectral differences in hair bleaching formulas.
