Ex-vivo Hair Testing by Eotech

Among the physical properties which describe the hair, its surface at the microscopic level shows small scales that affect the hair appearance. Hair with a shiny aspect has a smooth surface, well-shaped, where the scales are slightly raised and more spaced.

The hair surface topology is measured to evaluate smoothing or sheathing or even restorative effects.

According to a well-defined protocol we are doing these hair relief measurements thanks to an interferometric microscope technique on treated and not treated hair samples.

It quantifies the decrease of variables like the roughness parameters Rz and Ra as well as the parameter Lr which reflects the surface complexity.
