Surface analysis of permanent wave processing hair using DART-MS
After hair is applying permanent wave processing and coloring repeatedly, the chemical structure of a keratin molecule and fine structure in the hair have been damaged and it resulted as damage hair. It is thought that hair becomes dryness and twining if the cuticle which covers hair is damaged, so it is important to investigate the surface structure of hair and its chemical structure changing.
DART (Direct Analysis in Real Time), a direct atmospheric pressure ionization source, is capable of analyzing samples directly with little or no sample preparation. Here, analysis of the ingredient which has deposited on the permanent wave processing hair surface was tried using this DART combined with a mass spectrometer.
