Synopsis

We have developed a new method of fractionating hair components in order to analyze the damaged components and the degree of damage due to perming. We found that the amount of constituent proteins extracted by an anionic surfactant with reductant was influenced by the concentration of the reductant. Using this method, the matrix and the microfibril protein could be easily separated and quantified. Applying this method to the analysis of individual hairs, we found a significant decrease in the “intact” microfibril protein on the tip end of permed hair.
