Shampoo — TSA Rules Explained

You can bring Shampoo in your carry-on bag, but certain conditions apply. It is also allowed in checked baggage without restrictions. Shampoo is allowed with conditions in carry-on bags — 3.4 oz (100ml) or less, in quart-sized bag. Travel-sized containers of 3.4 oz (100ml) or less must fit in one quart-sized, clear, resealable plastic bag. TSA officers have the final say on what is allowed through the checkpoint. If you are unsure, check the TSA website or ask an officer at the airport.

How to pack shampoo for a flight

  • Carry-on: use travel containers of 3.4 oz (100 ml) or less. The printed capacity on the bottle is what matters, not how full it is.
  • All your liquids, gels, aerosols, creams, and pastes must fit inside one quart-sized resealable bag — one bag per passenger.
  • Solid shampoo bars are not liquids and are exempt from the 3-1-1 rule entirely, so they can be any size in carry-on.
  • Checked baggage: any bottle size is allowed. Seal the cap with tape and place the bottle inside a zip bag to contain leaks caused by cabin pressure changes.
  • Leave a little air space in refillable travel bottles so they do not burst or ooze at altitude.

What happens if your shampoo is too big for carry-on

  • The bottle shows on the X-ray and your bag is pulled for a quick bag check.
  • You can surrender the bottle, return it to your car, or check the bag if you still have time before your flight.
  • Oversized liquids are discarded — they are not held for you or returned after your trip.
  • Most airport shops past security sell travel-sized toiletries if you need a replacement.
