In this current study, we showed the structure and surface morphology of human hair with scanning electron microscopy. The effects of strain rate, relative humidity and temperature are investigated comprehensively, and the results show that the hair exhibits a changed tensile property under these influences. The elasticity and plasticity of hair after stretching to different strains are shown with cyclic tests. Finally, a constitutive equation is proposed based on the two-phase model and the experimental results. This model is considered to help to understand and analyze tensile behaviors of similar α-keratin fibers under certain conditions. Therefore, it is hoped that this study will be helpful in not only providing guidance in designing better cosmetic products, but also broadening our knowledge in the keratinous materials, which include wool, nail, horn and feathers.
