Caucasian blond Hair

This image shows the surface of a strand of hair taken from a Caucasian woman. The cuticle of the hair is the outermost layer. It is made up of a transparent, scale-like layer of overlapping cells. The function of these is to protect the cortex, the layer below the cuticle. This is a blond hair, which only contains two layers (lacks the inner medulla layer) and is, therefore, often thinner than other hair types.
