Are you looking to travel soon but don’t want to sacrifice your hair care routine? Many people wonder if they can bring dry shampoo on a plane. The short answer is yes, you can bring aerosol dry shampoo on carry-on and checked baggage as long as it adheres to the TSA’s 3-1-1 liquid rule.

But there are some regulations around aerosols you need to keep in mind.

In this comprehensive guide, we’ll walk through everything you need to know about bringing dry shampoo on a flight. We’ll cover TSA rules for aerosols in carry-on vs. checked bags, how much you can bring, tips for getting dry shampoo through security, and safe alternatives if yours gets confiscated.

TSA Rules for Aerosols in Carry-On Bags

When it comes to traveling with aerosols, such as dry shampoo, it’s important to be aware of the Transportation Security Administration (TSA) rules. These rules are in place to ensure the safety and security of all passengers on board.

Before packing your dry shampoo in your carry-on bag, it’s essential to understand the guidelines set by the TSA.

3-1-1 Liquid Rule

The 3-1-1 liquid rule is a fundamental guideline that applies to all liquids, gels, and aerosols in carry-on bags. According to this rule, all containers must be in a size of 3.4 ounces (100 milliliters) or less and placed in a single, clear, quart-sized plastic bag.

Each traveler is limited to one plastic bag, and it must be easily accessible for the TSA screening process. This rule also applies to aerosols, including dry shampoo.

Limits on Size and Quantity

When it comes to the size and quantity of aerosols, there are specific limitations imposed by the TSA. Each aerosol container must be 3.4 ounces (100 milliliters) or less and must fit within the quart-sized plastic bag.

It’s important to note that the TSA does not allow passengers to combine multiple containers to meet the limit. Each container must be individually within the size restrictions.

Additionally, there is a limit on the total quantity of aerosols allowed in carry-on bags. The TSA restricts passengers to a total of one quart-sized bag per person. This means you cannot bring multiple quart-sized bags filled with aerosols on the plane.

It’s crucial to adhere to these limits to ensure a smooth and hassle-free screening process.

TSA Screening and Approval

During the TSA screening process, all carry-on bags, including those containing aerosols, go through an X-ray machine. The TSA officers will visually inspect the bag and its contents to ensure compliance with the rules.

If there are any concerns or questions regarding the aerosol containers, additional screening may be required.

It’s worth mentioning that while dry shampoo is generally allowed in carry-on bags, it’s always best to check with the airline or the TSA directly for the most up-to-date information. Rules and regulations can vary, and it’s better to be well-informed before your trip.

TSA Rules for Aerosols in Checked Bags

No Size or Quantity Limits

When it comes to bringing aerosols, such as dry shampoo, in your checked bags, the Transportation Security Administration (TSA) does not impose any specific size or quantity limits. This means that as long as the aerosol canister fits within the size and weight restrictions of your checked baggage, you can bring it with you on the plane.

So, feel free to pack as many cans of dry shampoo as you need for your trip without worrying about exceeding any limits.

Must be Properly Packed

While there are no size or quantity limits for aerosols in checked bags, it is important to ensure that they are properly packed to comply with TSA regulations. The TSA requires that aerosols be packed securely to prevent accidental discharge.

This means that the canister should be tightly sealed and placed in a sturdy zip-top bag to contain any potential leaks or spills.

Pro Tip: To avoid any mishaps, it’s a good idea to place the zip-top bag containing the aerosol cans in the middle of your checked luggage, surrounded by soft items such as clothing or towels. This will provide an additional layer of protection and help prevent any damage to the cans during transportation.

It’s also worth noting that the TSA recommends notifying the airline or airport security if you are carrying any aerosols in your checked bags. While it may not be a mandatory requirement, it can help facilitate the screening process and avoid any potential misunderstandings or delays.

Tips for Getting Dry Shampoo Through TSA

Check Container Size Beforehand

Before you pack your dry shampoo for your upcoming flight, it’s important to check the container size to ensure it meets TSA regulations. The current rule states that liquids, gels, and aerosols must be in containers that are 3.4 ounces (100 milliliters) or less.

So, if your dry shampoo container exceeds this limit, unfortunately, you won’t be able to bring it on the plane in your carry-on bag. However, you can still pack it in your checked luggage without any issues.

Pack Smartly in Your Bag

If your dry shampoo container is within the allowed size limit, the next step is to pack it smartly in your bag. To avoid any spills or leaks, it’s recommended to place the dry shampoo bottle in a sealed plastic bag.

This will not only keep your other items in the bag safe but also make it easier for TSA agents to inspect if needed. Additionally, consider placing the dry shampoo container in an easily accessible part of your bag, as you may be asked to remove it during the security screening process.

Declare it at Security

When you reach the security checkpoint, it’s important to declare your dry shampoo, just like you would with any other liquid or aerosol item. This means taking it out of your bag and placing it in a separate bin for screening.

By doing so, you are following the proper procedure and ensuring a smooth security screening process. Remember, honesty is the best policy when it comes to airport security, and declaring your dry shampoo will save you from any unnecessary delays or complications.

Follow All Other Liquid Rules

While dry shampoo is not a liquid, it is still considered an aerosol. Therefore, it’s important to follow all other liquid rules enforced by the TSA. This includes placing all liquids, gels, and aerosols in a clear, quart-sized bag and limiting each container to 3.4 ounces or less.

Remember, these rules are in place to ensure the safety of all passengers, so it’s crucial to comply with them.

What Happens if Dry Shampoo is Confiscated?

When traveling with dry shampoo, it’s important to be aware of the rules and regulations regarding carry-on items. While dry shampoo is generally allowed on planes, there may be instances where it is confiscated by airport security. Here’s what can happen if your dry shampoo is confiscated:

You Can Opt to Leave Security to Remove It

If you are informed that your dry shampoo is not allowed in your carry-on baggage, you have the option to leave the security area and either dispose of it or place it in your checked luggage. This allows you to keep your dry shampoo and continue with your journey without any further issues.

However, it’s important to note that leaving the security area may cause delays, so it’s best to familiarize yourself with the rules beforehand to avoid any inconvenience.

TSA Will Dispose of It

If you choose not to leave the security area and decide to surrender your dry shampoo, the Transportation Security Administration (TSA) will dispose of it properly. The primary concern for airport security is the safety of all passengers, and if a particular item is deemed potentially hazardous or non-compliant with regulations, they have the authority to confiscate and dispose of it.

It’s always best to adhere to the rules to ensure a smooth and hassle-free travel experience.

You May Be Charged a Fee

In some cases, if you have oversized or prohibited items in your carry-on baggage, you may be required to pay a fee to have them placed in your checked luggage. This fee is typically charged by the airline and can vary depending on the airline’s policies.

It’s important to check with your specific airline regarding their regulations and fees for prohibited items to avoid any unexpected charges.

Safe Alternatives to Bring on a Plane

Leave it Behind and Purchase at Your Destination

If you’re worried about bringing your favorite dry shampoo on a plane, one safe alternative is to simply leave it behind and purchase a new one at your destination. Most airports have a wide range of beauty and personal care stores where you can find popular brands of dry shampoo.

This way, you can avoid any potential issues with TSA regulations and still have the convenience of using dry shampoo during your travels.

Switch to Dry Shampoo Sheets/Powder

If you prefer to bring your own dry shampoo, there are safe alternatives that you can consider. Dry shampoo sheets or powder are great options that are TSA-friendly and won’t cause any issues at security checkpoints.

These sheets or powders work similarly to traditional dry shampoo sprays, absorbing excess oil and refreshing your hair without the need for water. They are compact and easy to carry in your carry-on bag, making them a convenient choice for travelers.

Use Cornstarch as a DIY Dry Shampoo

If you’re in a pinch and don’t have access to dry shampoo or its alternatives, you can use a DIY option using cornstarch. Cornstarch works as a natural absorbent and can help remove excess oil from your hair. Simply sprinkle a small amount of cornstarch onto your roots and massage it in.

Let it sit for a few minutes, then brush it out thoroughly. This method can be a temporary solution until you can get your hands on a proper dry shampoo.

Remember, it’s always important to check the TSA guidelines and regulations before packing any personal care items in your carry-on bag. While dry shampoo is generally allowed, it’s always better to be safe than sorry.

By considering these safe alternatives, you can ensure a hassle-free travel experience without compromising on your hair care routine.


We hope this guide gave you all the details on whether or not you can bring dry shampoo in your carry-on or checked bags for a flight. The TSA has specific regulations for flying with aerosol containers, but you can likely get yours through security by following the tips above.
