ShampBooze® II allows each cruiser to bring aboard 34 oz of their own alcohol, saving a couple of hundred dollars on drinks. The ShampBooze® II holds 17oz of hidden alcohol like the beloved original ShampBooze®, but it also holds 1oz of a diversion shampoo or conditioner. In the unlikely event of a checked luggage inspection, opening the bottle and giving it a squeeze will only reveal a real hair product and its scent.

And to lose the drama entirely, we change the label with every manufacturing run, so it never gets flagged by the cruise lines. You’re welcome.
