The bizarre look is created by injecting saline into the forehead until
it swells up, and then pressing in the center of the swollen area with a
thumb. The result gives the appearance that someone has the
doughnut-shaped bread stuck to their head. The process takes two hours
to complete, but lasts just 16-24 hours, after which the saline is
absorbed by the body and the forehead shrinks to its normal size.
