The study "Vibrational Raman and IR data on brown hair subjected to bleaching" used Raman and infrared (IR) spectroscopy to examine the structural changes in brown hair after multiple bleaching treatments. The findings showed that bleaching significantly degrades keratin proteins and disrupts disulfide bonds, leading to changes in hair's secondary structure and increased oxidation products like cysteic acid. These molecular alterations were more pronounced after the third bleaching treatment. The study's detailed spectral data on these changes could help develop gentler hair treatments and effective restoration agents post-bleaching.
