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 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-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.
