Layers of Hair:-

Structurally hair is composed of three basic layers:

Cuticle is made from protein and water and responsible for the hair’s straightness, curliness, toughness, weakness, thickness and thinness. Cortex is the middle layer of the hair in between the cuticle and medulla, and responsible for most of the hair’s width, weight and visual properties. Inside the cortex there is medullary canal and it contains only air.
