While most 2026 cruise lines like Royal Caribbean, Carnival, and Norwegian provide basic soap and shampoo, they generally do not provide hairspray in cabins due to fire safety and aerosol regulations. You are, however, allowed to bring your own personal-sized hairspray in your luggage. If you forget yours, high-end "Luxury" lines like Seabourn or Silversea may include it in their upgraded vanity kits, or you can purchase it at the "onboard boutique" found on almost every major ship. In 2026, the "pro-tip" is to pack a non-aerosol pump spray to ensure it passes all security scans smoothly. Most cabins come equipped with a hairdryer, but for specialized grooming products like hairspray, travelers are expected to bring their own or visit the ship’s full-service onboard salon for professional styling.
