Cortex (hair) - Wikipedia
The cortex of the hair shaft is located between the hair cuticle and medulla and is the thickest hair layer. It contains most of the hair's pigment, giving the hair its color. The major pigment in the cortex is melanin, which is also found in skin. The distribution of this pigment varies from animal to animal and person to person.
Layers of Hair Shaft - Cuticle, Cortex and Medulla - Biology Reader
What are the layers of the hair shaft? The answer is there are three layers in the hair shaft; the medulla, cortex and cuticle. The medulla is the deepest layer of hair seen only in thick hairs. The cortex is the central layer of the hair shaft, giving strength, shine, colour and texture to your hair.

2024年3月17日 · The hair shaft is the visible, nongrowing portion of a hair protruding from the skin. This part of the hair is not anchored to the hair follicle. The hair shaft has three layers: a central medulla, a keratinised cortex and an outer layer, known as the cuticle, which is highly keratinised and forms the thin hard cuticle on the outside of the hair.
