Your hair consists of hair shafts.

How is elasticity test done?
This is to test the internal strength of the hair (the cortex). Hair that has been damaged due to chemical treatments may have lost much of its natural strength. This type of hair may stretch over two-thirds of its original length and may even break off. It is important to carry out this test before perming. Hair that is in good condition will stretch and then return to its original length. Take one strand of hair and hold each end firmly between the thumb and forefinger of each hand and gently pull. If the hair stretches more than half of its original length then it is over elastic and may snap or break during chemical processing.
