TSA regulations are clear—liquids must be in containers no larger than 3.4 ounces. That means large shampoo bottles, full-size perfumes, or big lotions are a no-go.

If you try to sneak them through, they’ll be confiscated. To avoid losing your favorite products, opt for travel-sized bottles instead.

2. Sharp Objects

Sharp items like scissors, knives, and box cutters are prohibited in carry-ons. Even small ones can get flagged at security, causing delays.

If you need them, pack them in your checked luggage instead. It’s not worth the hassle of losing your favorite nail scissors or pocket knife.
