Can You Bring Shampoo on a Plane? A Traveler’s Guide

Traveling by plane can be both exciting and daunting. Whether you’re a frequent flyer or a first-time traveler, there are several rules and regulations you need to be aware of when it comes to what you can and cannot bring on a plane. One common question that often pops up is, “Can you bring shampoo on a plane?” In this article, we will explore the ins and outs of traveling with shampoo, so you can have a stress-free journey.

Can You Bring Shampoo on a Plane?

Yes, you can bring shampoo on a plane in your carry-on luggage, but it must be in containers of 3.4 ounces (100 milliliters) or less and placed in a quart-sized, clear, resealable plastic bag.

Understanding TSA Regulations

The Transportation Security Administration (TSA) is responsible for ensuring the safety of air travel in the United States. They have specific rules in place regarding liquids and gels that you can carry in your carry-on baggage. It’s essential to familiarize yourself with these regulations before packing your shampoo.

Traveling with Carry-On Luggage

  1. TSA’s 3-1-1 Rule: The TSA follows the 3-1-1 rule for liquids and gels. This means you can bring liquids and gels in containers of no more than 3.4 ounces (100 milliliters) each. These containers must be placed in a quart-sized, clear, resealable plastic bag, with one bag allowed per passenger.
  2. Shampoo Bottle Size: Most shampoo bottles available in stores are well within the TSA limit. Travel-sized shampoo bottles are usually 3.0 ounces or smaller, making them suitable for carry-on luggage.
  3. Exceptions for Medically Necessary Liquids: If you require specific shampoo for medical reasons, such as a prescribed treatment, you are allowed to bring larger quantities. However, you must declare them to TSA officers for inspection.

Checked Luggage

  1. No Size Limit for Checked Bags: If you prefer to travel with larger bottles of shampoo or other liquids, you can pack them in your checked luggage. There are no size restrictions for liquids in checked bags.

Tips for Hassle-Free Travel

  1. Invest in Travel-Sized Toiletries: To avoid any hassle at security checkpoints, consider purchasing travel-sized toiletries. They are readily available in most stores and come in TSA-approved sizes.
  2. Know Your Shampoo Ingredients: Some shampoos may contain ingredients that are prohibited or subject to additional scrutiny. Check the ingredient list and, if in doubt, transfer your shampoo to a smaller, approved container.
  3. Pack Securely: To prevent leakage, make sure your shampoo bottle is tightly sealed and placed in a resealable plastic bag. You can also use plastic wrap as an extra precaution.


In conclusion, yes, you can bring shampoo on a plane, but there are rules you must follow to ensure a smooth and stress-free journey. Familiarize yourself with TSA regulations, opt for travel-sized toiletries, and pack your shampoo securely to avoid any mishaps during your flight.


Can I bring a full-sized shampoo bottle in my carry-on bag?

No, you cannot bring a full-sized shampoo bottle in your carry-on bag. It must comply with the TSA’s 3-1-1 rule.

What if I have a medical condition that requires a specific shampoo?

If you have a medically necessary shampoo, you can bring it in larger quantities, but you must declare it to TSA officers.

Are solid shampoo bars allowed on a plane?

Yes, solid shampoo bars are generally allowed in carry-on luggage as they are not considered liquids.

Can I bring conditioner and other hair products on a plane?

Yes, you can bring conditioner and other hair products as long as they meet the TSA’s 3-1-1 rule.

Is there a limit to the number of shampoo bottles I can bring in my carry-on bag?

You can bring as many 3.4-ounce (100-milliliter) bottles of shampoo as will fit in a quart-sized, resealable plastic bag, with one bag allowed per passenger.

Now, before you embark on your journey, remember to check the TSA regulations, pack your shampoo wisely, and have a great flight!
