I was trying to find something new for my DD to do, when I came up with this (it's probably something you're all doing anyway!)... Find large pictures of people's faces (magazine covers are a good place to start) and cut out the head, but cut off the hair. Glue onto white paper or card and let your charge 'create' the hairstyle. They could use pencils, crayons, markers, highlighters, wool, glitter glue, fur...anything that's available really! I'll try and get a pic on to show you our work.
