An apparatus for sequentially and individually heating hair rollers incorporates a turn tray having a plurality of receptacles. The turn tray rotates, and if a roller is disposed in the receptacle, the turn tray will stop at a steam stage area where the roller is subjected to heat and steam. After a predetermined of time selected by the operator, e.g., when the hair roller is sufficiently treated with heat and steam, the roller is removed and applied to a length of hair of the operator. The turn tray will then automatically rotate to place the next successive roller within the steam stage area.
