If you’re like many men and women and have discovered the joys of dry shampoo, you might be wondering if you can bring it on your next flight.

According to TSA regulations, you can bring dry shampoo on a plane in both your carry on and checked bags, though if packed in your carry on, the bottle must not exceed 3.4oz/100ml.

But what are the rules when it comes to flying internationally with dry shampoo?

What about other types of shampoo and haircare products – are they allowed?

Can You Bring Dry Shampoo on a Plane?

Carry on Bags

Due to the TSA’s 3-1-1 Rule, you can pack dry shampoo in your carry on bags in containers no larger than 3.4oz/100ml.

This is because the TSA’s 3-1-1 Rule covers liquids, gels, and aerosols, which dry shampoo falls under.

Any container of dry shampoo must be placed in a 1 quart-sized bag, which should be taken out of your bag and placed in a screening bin as you go through airport security.

Checked Bags

You can pack dry shampoo in your checked bags, though there are a couple of limits you need to keep in mind.

The TSA states that any container of dry shampoo must not exceed 0.5 kg (18 ounces) or 500 ml (17 fluid ounces).

The total aggregate quantity of your toiletry products must also not exceed 2 kg (70 ounces) or 2 L (68 fluid ounces), with dry shampoo counting towards this allowance.

Domestic vs. International Flights

Even though the TSA only has authority in the USA, you will find that the same rules apply.

So, if you want to bring dry shampoo on a plane in your carry on, the container must not exceed 3.4oz/100ml regardless if you are flying to or from Canada, Mexico, the UK, Europe, or any other countries.

By Airline

Airlines follow TSA regulations.

So, again, this means that if packed in your carry on, dry shampoo must not exceed 3.4oz/100ml.

If packed in your checked bags, dry shampoo must not exceed 0.5 kg (18 ounces) or 500 ml (17 fluid ounces) per container.

Can You Bring Other Types of Shampoo on a Plane?

Liquid Shampoo

You can bring liquid shampoo on a plane in both your carry on and checked bags, but you are limited to a bottle that does not exceed 3.4oz/100ml if you pack it in your carry on.

Powder Shampoo

If the powder shampoo is greater than 350mL or 12 oz. it is allowed in your carry on bags, but it may require additional screening as you go through airport security.

The TSA recommend that you pack powder shampoo in your checked bags for your convenience.

Medical Shampoo

If medical shampoo has been prescribed, you are allowed to bring a bottle that is larger than 3.4oz/100ml.

It is recommended that you travel with your prescription and declare to a TSA agent that you are traveling with a liquid that exceeds the standard regulations.

How Many Bottles of Dry Shampoo Can You Bring on a Plane?

In total, you are allowed to bring 32 ounces of liquids, gels and aerosols on a plane (or 1 quart of liquids).

This means that you can bring approximately 7-8 bottles of dry shampoo on a plane in your carry on bags, due to the space the bottles themselves will take up in your single quart-sized bag.

Will Dry Shampoo Explode on a Plane?

Due to the changes in pressure and temperature on a plane, dry shampoo has a very small yet unlikely chance of leaking, igniting or even exploding on a plane.

Can You Bring Dry Conditioner on a Plane?

When bringing dry conditioner on a plane, the same rules apply as for dry shampoo.

So, if packed in your carry on, dry conditioner should not be in a container that exceeds 3.4oz/100ml.

Can You Bring Hairspray on a Plane?

You can bring hairspray on a plane in both your checked bags and carry on bags.

If packed in your carry on bags, the container must be less than or equal to 3.4 oz/100 ml.

Note that the TSA state that “release devices (button/nozzle) must be protected by caps or other suitable means to prevent accidental release.”

Can You Bring Hair Gel on a Plane?

If you want to bring hair gel on a plane in your carry on, the container must not exceed 3.4oz/100 ml.

The same applies to hair wax, mousse, paste, pomade, and all other hairstyling products.

Can You Bring Curling Irons or Hair Straighteners on a Plane?

The TSA state that you can bring hair straighteners and curling irons on a plane in both your carry on and checked bags.

If they contain batteries or gas/fuel cartridges, they must be packed in your carry on.
