Question:
Why doe's the tensile strength of human hair decrease with temperature increase ?


Replies:
Some denaturing of the protein...i.e., breaking of certain cross linking bonds between the keratin fibers disulfide bonds etc. This is related to why moderate heating and setting of hair is a way to reorganize the appearance of hair...ironing to straighten the hair of curling irons to curl it.
