Figure 3: Typical stress–strain plots obtained from single fiber tensile testing of hair collected from four positions (P1–P4) of the scalp. (a) Male 15 years and (b) Female 29 years. In both cases, R1 is the Hookean or preyield region, R2 indicates the start and end of the yield regions (plateau of almost constant stress), and R3 and R4 are postyield regions-1 and 2. Note that yield does not correspond to the onset of plastic deformation
