Yes, you are permitted to bring a hair curling iron, hair straightener, or hair dryer on a Royal Caribbean cruise. Unlike clothing irons or steamers, which are strictly prohibited due to being high-fidelity fire hazards, hair tools are considered safe for stateroom use. Royal Caribbean's security team requires that these devices be in good working condition without frayed cords. Each stateroom is also equipped with a built-in hair dryer, though many guests prefer to bring their own for better performance. It is worth noting that you should always unplug your curling iron when not in use, as stateroom attendants may confiscate any heat-producing tool left on and unattended for safety reasons. In 2026, the ship's "High-Fidelity" electrical systems are designed to handle these standard personal care appliances, but "travel-sized" versions are still recommended to save space in the compact vanity areas.
