The multi-chamber tube package can be a tube-in-tube package with an outer tube with an outer chamber that contains a conditioning composition and an inner tube with an inner chamber that contains a warming composition. The inner chamber is fluidly connected to one or more central orifices by an inner nozzle channel and the outer channel is fluidly connected to one or more outer orifices by an outer channel. The ratio of the area of the central orifice(s) to the outer orifice(s) can be greater than 1. The ratios can help the product dispense as a single stream with two visible phases, which has been found to prompt the consumer to intuitively mix the composition, thereby activating a warming sensation.
