This pilot study found that prebleaching either virgin or previously colored hair only slightly affects the SERS spectra of dyes applied afterward, without impacting the accuracy of dye identification, supporting the technique's robustness for forensic analysis of hair dyes.

This study observed that bleaching brown human hair with persulfate salts and hydrogen peroxide induced significant conformational changes in keratin, particularly affecting disulfide bridges and oxidized sulfur species, which may inform the development of hair restorative treatments.

This study found that the PLEE method increased hair protein extraction efficiency threefold and that bleaching hair reduced the coverage of keratin and associated proteins, leading to poorer hair quality, though it did not affect the overall protein identification.

This study found that hair pH normalization occurs in three predictable phases within 72 hours after bleaching, and the authors propose a structured stabilization protocol to improve hair recovery during this period.

In this study, researchers observed that cosmetic peroxide bleaching causes oxidative damage and protein loss in human hair, not only affecting the cuticle but also deeper cortical structures, correlating with bleaching severity.
