Can you bring eyebrow scissors on a plane? Key regulations explained
In the United States, small eyebrow scissors are generally allowed on planes, but whether you can bring them depends on their size and type. According to the explicit regulations of the U.S. Transportation Security Administration (TSA), as long as the blade of the eyebrow scissors measures less than 4 inches (10.16 cm) from the center point to the tip and does not fall under the category of hazardous materials, they can be carried in carry-on luggage; if the blade length exceeds 4 inches, they must be checked in and cannot be carried on board.
Three methods: Verify if eyebrow scissors meet carry-on standards
To quickly determine if eyebrow scissors meet U.S. airline carry-on regulations, use the following practical methods.
First, the ruler measurement method
Use a centimeter ruler or inch ruler. Open the scissors and measure from the center point where the two blades meet to the tip of the blade. If the result is less than 4 inches, it meets the requirements.

Second, refer to the product specifications
Check the scissors’ product manual or packaging. Some manufacturers clearly indicate the blade length. If it is less than 4 inches, you can carry them on board directly.
Lastly, the common item comparison method
If you don’t have a ruler, you can compare them with a credit card (approximately 3.37 inches/8.56 centimeters in length). If the scissors’ blades are significantly shorter than the credit card, they typically meet the regulations.
Carrying eyebrow scissors on U.S. flights: 2 important notes
Even if the eyebrow scissors meet TSA regulations, there are two points to note.
First, different airlines may have different requirements
TSA regulations are the basic standard, but some airlines may have more detailed requirements. It is recommended to confirm the specific carry-on rules of the target airline through its official website or customer service before traveling.
Second, cooperation is required during security screening
When carrying eyebrow scissors through security screening, they must be removed from luggage and inspected by security personnel. Only after confirmation of compliance with regulations can they be successfully carried through.
