01The rules in detail
Standard plug-in hair tools are unrestricted. Cordless lithium-battery models follow battery rules — cabin only. Gas-powered curling irons with a butane cartridge are allowed in carry-on (one device, cover on) but spare cartridges are banned everywhere; some airlines ban the device outright. Check voltage compatibility abroad — many straighteners aren’t dual-voltage and will burn out.
02Tips
- Confirm dual voltage (100–240 V) before packing for another continent.
- Let it cool before packing; a heat-proof pouch helps.
03Frequently asked
Can I bring a hair straightener or curling iron in my carry-on?
Yes, with limits. Corded straighteners and curling irons are fine in both bags. Cordless (battery) models: carry-on only with the battery protected. Butane (gas) cartridge models: one on your person or in carry-on with a safety cover, no spare cartridges.

Are the rules the same outside the US?
Mostly similar for liquids and batteries, which follow international standards, but sharp objects, tools, lighters and self-defense items vary widely by country. Check the departure airport's rules and the destination's laws.
TSA and other agencies allow officers to refuse any item they judge unsafe, and rules change. This page summarises published guidance as of the verified date; confirm on tsa.gov or your airport's site before packing anything unusual.
