Hair shaft anatomy. Cutaway artwork showing the internal structure and anatomy of a human hair. Hair is made of a fibrous protein called keratin,with an outer cuticle layer protecting the inner cortex and medulla layers. The medulla is at the centre of the shaft,surrounded by cortical bundles that consist of various sizes of fibrils and filaments. The hair shaft arises from a hair follicle below the surface of the skin,with the emergence from the skin shown at bottom | |
