Your hair begins growing from a root in the bottom of the follicle. The root is made up of cells of protein. Blood from the blood vessels in your scalp feeds the root, which creates more cells and makes the hair grow. The hair gets pushed up through the skin as it grows, passing an oil gland along the way.
