Hair fulfils versatile functions such as heat & light protection, moisture protection & regulation and camouflage.
In humans and mammals, hair is roughly composed of three layers: From inside to outside the medulla, cortex and cuticle. The cuticle, also called the cuticle layer, consists of keratinized dead cells.

In healthy hair, this outer layer lies close together and ensures the healthy shine of the hair.
We can quickly and accurately check the structure and quality of this outer cuticle layer with the scanning electron microscope.

Background information: Humans have between about 75,000 and 150,000 head hairs. As a rule, most hair is blonde, the fewest redheads. Hair has a variable diameter of about 0.05 mm. They can be round, oval or even triangular. This can be observed particularly well with hair cross sections.
