Detailed explanation-1: -But all the hairs you see on your body have at least one thing in common: They’re actually dead. Under a microscope, each of your individual hairs looks like a thick tube. This structure is called a filament, or hair shaft. A strong protein called keratin is what most of your hair is made of.
Detailed explanation-2: -The root is the living part of the hair that sits in the dermis, the middle layer of the skin. The root is surrounded by the follicle, which is typically attached to a sebaceous (oil) gland in the skin.
Detailed explanation-3: -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.
