Furthermore, since hair is dead, it cannot be nourished, only preserved.

The hair gets pushed up through the skin as it grows, passing an oil gland along the way. The oil gland adds oil to the hair and keeps it shiny and soft. It can make it greasy, too.

Hair is considered both dead and alive. Hair follicles include tiny blood vessels that are designed to keep it growing. This part of the hair is alive.
