Having a bagel head is the latest beauty craze. In Tokyo, forehead saline injections -- which basically make you look like a mini-bagel has been inserted between your skin and your skull -- are the current body-mod craze. After the bulge is created, the artist manipulates it with his fingers, creating an indentation with his thumb. On the scene since around 2008, the bagel head isnt permanent. In fact, it only lasts around 16 hours, at which point your body absorbs the saline and your head goes back to normal.
