In 2026, MSC Cruises officially allows guests to bring their own hair dryers, hair irons, and hair straighteners on board. Unlike clothes irons or electric kettles, which are strictly prohibited fire hazards, hair styling tools are considered safe for cabin use. However, MSC cabins are already equipped with a standard hair dryer—usually located in the vanity drawer rather than the bathroom—so most travelers find they can save luggage space by leaving theirs at home. If you do bring your own, 2026 cruise veterans recommend checking the voltage, as some ships use 220V European-style outlets while others have 110V US-style outlets. High-wattage devices like the Dyson Airwrap can sometimes trip the cabin's circuit breaker or fail to function properly due to the ship's unique electrical grid. If your personal dryer causes an electrical surge, it may be confiscated by the ship's security team and returned to you at the end of the voyage for the safety of the vessel.
