Hair straighteners and vapes are rarely “banned” outright; most restrictions stem from lithium battery fire risks, making packing method—not the item itself—the deciding factor.
Many travelers have been alarmed by the news that TSA doesn’t allow vapes or hair straighteners. The reality is more complex. “Most things are granted, but it’s how you pack them that makes the difference.”
Direct answer: Vapes must and should be packed in carry-on luggage, which means they are not to be checked, but corded hair straighteners are granted, except for cordless/battery-powered models, because of lithium battery rules and regulations.
Are Hair Straighteners and Vapes Banned?
No. Most of the confusion comes from misinterpreting the regulations.
Banned: Items that pose an unavoidable risk.
Restricted: Items that are granted only if used safely.
This is the reason why a vape in a carry-on is granted but not in checked luggage.
