Is Hair Product Considered a Liquid When Flying?

In the world of travel, whether for business or leisure, one thing that often raises questions is what items are allowed in carry-on luggage, especially when it comes to liquids. Many travelers are unsure about whether their hair products fall into the category of liquids and what rules and regulations apply to them.

In this article, we’ll dive into the intricacies of carrying hair products on flights, discussing what constitutes a liquid, the TSA guidelines, and tips for hassle-free air travel with your favorite haircare essentials.

Is Hair Product Considered a Liquid When Flying?

Yes, hair products are generally considered liquids when flying. Most airports and airlines follow the Transportation Security Administration (TSA) guidelines, which classify gels, creams, and liquids as part of the 3-1-1 rule. This means that each passenger can carry containers of liquids, gels, or creams that are 3.4 ounces (100 milliliters) or less per item, and they must be placed in a quart-sized, clear, resealable plastic bag.

Understanding the Definition of Liquids

Before we delve into the specifics of flying with hair products, it’s essential to understand what qualifies as a liquid in the context of airport security. Typically, a liquid is considered any substance that flows freely, takes the shape of its container, and can pour or drip. This includes common items like water, shampoo, lotion, and even gels. However, not all products you use for your hair necessarily fit this definition.

Classifying Hair Products

Hair products come in various form, including liquids, gels, creams, and sprays. To determine whether your hair product is considered a liquid when flying, you should look at its consistency. Here’s a breakdown:

1. Liquid Hair Products

Liquid hair products, such as hair serums and oils, are undoubtedly classified as liquids. They have a flowing consistency and typically come in bottles with screw caps or pumps.

2. Gels and Creams

Gels and creams can also be considered liquids if they meet certain criteria. If they have a viscous, pourable texture, they may fall under the liquid category.

3. Solid Hair Products

Solid hair products, like wax or pomade, do not qualify as liquids. They have a firm, non-flowing texture and are generally safe to carry in your hand luggage.

TSA Guidelines for Hair Products

Now that we’ve clarified how different hair products are categorized let’s explore the Transportation Security Administration (TSA) guidelines regarding these items.

Carry-On Liquid Limitations

The TSA enforces strict rules for liquids in carry-on bags. Each passenger is allowed to bring a quart-sized, clear, resealable bag containing containers of liquids, gels, and aerosols. These containers must not exceed 3.4 ounces (100 milliliters) each.

Exceptions for Medically Necessary Products

It’s important to note that the TSA makes exceptions for medically necessary liquids, including prescription hair products. However, you must inform the security personnel about these items during the screening process.

Additional Considerations

To ensure a smooth experience at the airport, consider the following:

  • Travel-Size Containers: Transfer your hair products into travel-sized containers that meet TSA regulations.
  • Check-In vs. Carry-On: If you have larger quantities of hair products, consider checking them in rather than carrying them in your hand luggage.

Tips for Traveling with Hair Products

Traveling with your favorite hair products doesn’t have to be a source of stress. Here are some tips to make the process easier:

1. Plan Ahead

Before your trip, review TSA guidelines and ensure your hair products comply with the regulations. This can help you avoid last-minute inconveniences at the airport.

2. Choose Wisely

Opt for travel-sized versions of your hair products whenever possible. These are not only convenient but also reduce the chances of exceeding the liquid limitations.

3. Secure Containers

Ensure that your hair product containers are tightly sealed to prevent leaks during the flight.

4. Carry a Travel-Size Hairdryer

Consider packing a compact travel-size hairdryer in your checked luggage to avoid the need for bulky styling tools in your carry-on bag.

5. Be Prepared to Declare

If you’re carrying medically necessary hair products, have documentation ready to declare them at security checkpoints.


In conclusion, the classification of hair products as liquids when flying depends on their consistency. While liquid and pourable products fall under the liquid category, solid products are exempt. It’s essential to familiarize yourself with TSA guidelines, plan ahead, and choose the right containers to ensure a hassle-free travel experience with your hair products.
