On a Carnival cruise, the availability of toiletries depends largely on your stateroom category, but there is a baseline for every guest. In standard interior, ocean-view, and balcony staterooms, Carnival provides liquid soap and shampoo via wall-mounted dispensers in the shower. It is important to note that, unlike some luxury lines, Carnival typically does not provide a separate conditioner in these dispensers; it is usually a basic "shampoo" formula. Many guests find this product to be somewhat drying for certain hair types, so bringing your own travel-sized conditioner is a common "pro-tip" for Carnival cruisers. However, if you are staying in Cloud 9 Spa staterooms or certain high-end suites, you will often find upgraded, individual-use Elemis brand toiletries which include separate shampoo, conditioner, and body lotion. For everyone else, the basic dispensers are there for convenience, but they are utilitarian. If you have specific hair care needs or prefer a certain brand, you should pack your own, as the onboard "Fun Shops" sell these items at a significant premium compared to landside drugstores.
