Abstract
A method to measure heat damage of keratin fibers comprising eluting a peptide from a hair sample with an aqueous solution; extracting the peptide using a suitable solvent sample; analyzing the peptide samples with MALDI-MS; resulting in peptide results; identifying presence of a marker peptide and identifying the m/z ratio for the peptide.
