If you have a particular hair routine you want to maintain during your vacation, it's important to be aware that TSA has banned these hair tools.

“Cordless hair straighteners that contain lithium metal or lithium ion batteries or are gas or butane fueled are only allowed in carry-on bags,” a notice on the TSA website states. “A safety cover must be securely fitted over the heating element. The device must be protected from accidental activation.”

In addition to the enactmentment of the REAL ID requirement in May, earlier this year, TSA banned portable chargers and power banks with lithium-ion batteries from checked luggage, according to the FAA. Lithium batteries can pose a fire hazard and are subject to overheating and creating sparks, especially if damaged.
