The hair shaft is the visible part of the hair that protrudes from the skin surface. It consists entirely of keratinized, dead cells filled with keratin. The hair shaft itself is therefore no longer alive and is continuously regenerated by the hair root. Anatomically, it is divided into three layers: the cuticle (scaly layer), which protects the hair, the cortex (fibrous layer), which determines stability and elasticity, and the medulla (marrow canal), which is only found in thick hair.
