Scarlett – How does you grow your hair?

2 comments:

  1. Hair grows out of little pockets in your skin called follicles. The hair gets pushed up through the skin passing an oil gland along the way. The oil gland adds oil to the hair making it shiny and soft. It can make hair greasy too, which is why you need to wash your hair. The hair dies when it pokes through the skin and that is why it doesn’t hurt to cut your hair. Blood from blood vessels in your scalp feed the root of your hair which creates more cells and makes the hair grow.
