Abstract

For straight perm, the microscopic mechanism is still unclear, especially for changes in the secondary structure of the protein of the hair. Expecting to find a better condition for the straight perm treatment, we made the research on grey hair using the Raman imaging technique and principal component analysis (PCA). We succeeded to detect changes in different secondary structures such as β-turn and α-helix and to visualize their distributions.
