FT-Raman spectroscopy–Applications in hair research
Chandra M. Pande

Synopsis

FT-Raman (Fourier transform Raman) spectroscopic measurements have been performed on human hair. This technique provides a rapid and non-destructive in situ method for monitoring the disulfide bonds and their oxidation and reduction products in hair. The aromatic amino acids, by virtue of their side chains, are also clearly discernible in the spectra. It is shown that the effect of cosmetic hair treatments that modify the disulfide bonds, such as permanent waving and bleaching, can be conveniently monitored. Hair photodamage studies reveal that besides damage to the disulfide bonds, the peptide backbone is significantly affected. These data suggest that the FT-Raman technique is ideally suited for hair research and will find practical use in the formulation and testing of milder, less damaging, cosmetic products for hair.
