Based on a series of experiments, the authors put forward the Fractional Damage Theory of Hair Scales: not all types of hair scales are prenatally formed. When environmental factors work on the hair, fractional damages happen on a few types of scales like regular smooth type to form the irregualr wave type. The complexity of irregular wave type is related to the fraction mode and intensity. Physical and chemical factors may promote or weaken scale damage degree. Fractional damage of hair scales is effective protective adaptation. The Fractional Damage Theory of Hair Scales is of great importance in promoting fur products process, caring fur products, beautifying and caring hair as well as species identification techniques by hair morphology.
