In response to a couple of comments. This image is in fact just one image. When we were trying to compose it, the model leaned her head forward and pushed as much flour as she could onto her hair and then threw her head back for the shot. This did not work so I suggested she try the same method but to lean as far back as possible and throw her head forward. She required to keep her arms out to balance herself which worked well for the final image. It took 4 takes until I was happy with the hair and flour flow. Again thank you everyone for your comments. Bob.
