Can Hair Straighteners Be Checked In?

Yes
‌Hair straighteners can be checked in, but you need to pay attention to whether they contain lithium batteries. The specific regulations are as follows:

‌Lithium battery handling‌: If the hair straightener contains lithium batteries, according to aviation safety regulations, the lithium batteries must be carried with you and cannot be checked in. If there are no batteries, you can check them in with confidence.

‌Packing requirements‌: When checking in, make sure that the hair straightener is packed intact to avoid damage or safety hazards.

‌Airline differences‌: Although it is generally allowed to be checked in, it is recommended to confirm the baggage regulations of the specific airline before departure to avoid accidents.

In summary, hair straighteners without lithium batteries can be checked in normally, while those with built-in lithium batteries need to remove the batteries and carry them with you.
