GENERAL HISTOLOGY

Detailed explanation-1: -The shaft is the visible part of the hair that sticks out of the skin. The hair root is in the skin and extends down to the deeper layers of the skin. It is surrounded by the hair follicle (a sheath of skin and connective tissue), which is also connected to a sebaceous gland.

Detailed explanation-2: -Your hair shaft is the part of your hair that can be seen above your scalp. It is made of a protein called keratin, compacted and fused together.

Detailed explanation-3: -The hair shaft is formed of three layers: The medulla – the deepest layer of the hair shaft, only seen in large and thick hairs. The cortex – the middle layer of the hair shaft which provides the strength, colour and texture of a hair fibre. The cuticle – the outer layer of the hair shaft is thin and colourless.

Detailed explanation-4: -The cortex is the middle layer, and it composes most of the hair shaft. It also contains much of the melanin that gives hair its color. The outermost layer is called the cuticle.
