💇 Hair dryer

Nothing — hair dryers are permitted in both carry-on and checked baggage worldwide, so screeners will simply let it through. There are no wattage or voltage restrictions imposed at the security checkpoint itself, though some countries use different electrical standards that may affect whether the dryer works at your destination.

No. Hair dryers are universally permitted in both carry-on and checked baggage across all regions, including the US, EU, UK, Australia, Canada, and beyond. Unlike some personal care devices, they contain no hazardous components that trigger aviation restrictions.

A hair dryer can show up as a dense object on X-ray and may prompt a bag check, but once identified it will be cleared without issue. If your bag is opened, simply let the officer know what it is — there is nothing to explain or negotiate.

Either works from a security standpoint, but checked baggage is usually more practical given a hair dryer's bulk. If you are traveling carry-on only, it will fit in most standard carry-on bags and poses no security issue.
