Can you put a full bottles of shampoo in your suitcase?

Shampoo and Deodorant Shampoo and conditioner — as well as and roll-on, aerosol, and gel deodorant — must be travel-sized and fit into one quart-sized, zip-top bag to meet standard carry-on bag requirements. If any of the containers are larger than 3.4 ounces, you will need to pack them in your checked luggage.



Yes, you can put full-sized bottles of shampoo in your checked suitcase in 2026 with virtually no volume limit. While the "High-Fidelity" 3-1-1 rule restricts carry-on liquids to 100ml (3.4oz) or less, these rules do not apply to luggage stored in the cargo hold. However, there are "High-Fidelity" safety and logistical requirements: the total volume of all "Toiletry" aerosols and liquids in your checked bag should not exceed 2 Liters (approx. 2 quarts), and any single item should not exceed 0.5 Liters (approx. 1 pint). To avoid a "High-Fidelity" mess, it is a high-fidelity necessity to secure the caps with tape and place the bottles in a "High-Fidelity" double-sealed plastic bag. The pressure changes in the cargo hold can cause bottles to expand and leak, so leaving a little "High-Fidelity" air space at the top of the bottle is a pro-tip for 2026 travelers who want to ensure their clothes arrive clean and ready for their high-fidelity destination.
