Which Shampoos Are Allowed on Airplanes?

Traveling by air entails meticulous planning and adherence to regulations set forth by aviation authorities, including the Transportation Security Administration (TSA). Among the essential items travelers often carry is shampoo, a staple in personal hygiene routines. However, understanding TSA rules regarding the transportation of shampoo is imperative to ensure a smooth travel experience. This article aims to elucidate TSA regulations governing the transportation of shampoo on both carry-on and checked luggage, addressing common queries and providing practical guidelines for travelers.

Is Shampoo Allowed on a Plane?

According to TSA regulations, passengers are permitted to bring shampoo on a plane, whether in their carry-on or checked luggage. However, certain restrictions and guidelines must be observed to comply with TSA rules and facilitate hassle-free travel.

Carry-on Bag Regulations

Passengers can bring shampoo in their carry-on bags, subject to the TSA’s liquid rule (3-1-1). This rule stipulates that each container of liquid, gel, or aerosol must be 3.4 ounces (100 milliliters) or smaller and placed in a single clear, quart-sized plastic bag. Therefore, travelers can carry up to 3.4 ounces of shampoo in their carry-on bag, ensuring compliance with TSA regulations.

Checked Luggage Regulations

In contrast to carry-on luggage, there are no specific restrictions on the size or quantity of shampoo that can be packed in checked luggage. However, travelers are advised to pack shampoo in sturdy containers to prevent leaks and spills during transit. Additionally, wrapping the container in bubble wrap or plastic wrap provides added protection against leaks, minimizing the risk of damage to other items in the luggage.

Types of Shampoo and Additional Guidelines

Dry shampoo spray, powdered shampoo, and medicated shampoo are subject to varying regulations:

  • Dry Shampoo Spray: Travelers can bring dry shampoo spray in their carry-on bag, adhering to the 3.4-ounce limit imposed by the TSA. For quantities exceeding 3.4 ounces, passengers may pack dry shampoo spray in their checked luggage.
  • Powdered Shampoo: Powdered shampoo exceeding 12 ounces may be packed in a carry-on bag but will undergo additional checks at airport security checkpoints. However, the TSA recommends avoiding packing powdered shampoo in checked baggage to prevent potential complications.
  • Medicated Shampoo: Passengers are permitted to bring medicated shampoo exceeding 3.4 ounces, provided they inform TSA personnel during security screening.


In summary, travelers are allowed to bring shampoo on a plane, with regulations governing its transportation in both carry-on and checked luggage. Adhering to TSA guidelines, including the 3-1-1 liquid rule, ensures compliance and facilitates a seamless travel experience. By understanding and following TSA regulations about shampoo, passengers can navigate airport security with confidence and embark on their journeys well-prepared.
