BJECTIVE More parameters have been used for more detailed description of mechanical properties of human hair as a fibre than in analogous studies. All measured samples were taken from five different locations on the heads of 60 women of varied age.
METHODS For each hair, the diameter was determined optically and then the test in the Deform Type 2 testing machine was carried out. Deformation curves were obtained by testing 10 mm long samples up to the rupture point at constant temperature, humidity and constant crossbar speed of 2 mm/min.
The curves were processed with software for the calculation of mechanical parameters of the hairs. This specialized software has been designed by us for that purpose.
Resulting values were arranged into tables and figures.
