Sometimes in shopping centres you will see people selling little glass-like cubes containing tiny bubbles forming an image. Those that offer to place your own image in the cubes have a laser scanner that resembles a passport photo booth. The cubes start at around £10, and you should be to persuade them to let you have a copy of the .XYZ file if you have a memory stick.
It doesn't do the back of the head- or under the chin!- but 'hair' would need massaging before 3D printing anyway.
In El Reg's last 3d printing article, they made a small 2D vulture... since there is a stuffed vulture in the office, why haven't you scanned that with the Kinnet?
