Hair grows out of tiny pockets in your skin called ‘follicles’. It grows from roots made up of cells of proteins. There are blood vessels under your scalp which feed the blood giving rise to more cells and thereby making the hair grow.

As it grows, it passes the oil glands (sebaceous) which add oil to hair keeping it shiny and lustrous. The hair shaft is the part of the hair you see outside is actually dead hair. It’s only the root that grows!
