MICROANATOMY

Detailed explanation-1: -The living tissue that makes your hair grow is hidden inside the hair follicle. The shaft, the part of a hair that you see, is made of cells that aren’t living anymore.

Detailed explanation-2: -Hair is also made both of living and non-living components below and above the level of the epidermis. Above the level of the epidermis, the hair shaft is a thin, flexible cylinder of non-living, keratinized epithelial cells.

Detailed explanation-3: -Each hair has a hair shaft and a hair root. 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-4: -Hair is consisted of two distinct structures: follicle-the living part located under the skin and hair shaft-fully keratinized nonliving part above the skin surface. The arrector pili muscle, takes place between the hair bulge area and dermoepidermal junction.

Detailed explanation-5: -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.
