The short answer
Yes, if the blades are less than 4 inches (10 cm) long measured from the pivot point. Larger scissors must go in checked luggage. Rounded kids’ scissors and nail scissors are almost always under the limit.

How to measure
Put a ruler at the screw where the two blades cross and measure to the tip of the blade. If that distance is under 4 inches (10 cm), the scissors are allowed in your carry-on. The handles don’t count. The officer can still refuse anything they judge to be a risk.
