The Italian coach is believed to have had one installed in City's home ground of the Etihad Stadium in order to straighten up his hair before doing post-match interviews.
"He doesn't like going on TV looking wet," The Mirror quotes a source as saying. "He likes to look good. It's part of his suave image."
Reports have claimed that Mancini keeps the hair accessory in the staff area of the ground away from the players.
