Can You Bring Hair Spray on a Plane? Making TSA’s Rules Stick [2023]

Using hair spray is one of the easiest ways to keep your hair on point when traveling. But there is a major point of confusion when it comes to bringing hair spray through airport security and on a plane.

For example, can you bring aerosol cans of hair spray and are there certain size restrictions?

In this article, I will clear up all of the confusion and provide you with clear explanations as to the type of hair spray you can bring and give you tips on the best ways to bring it.

I’ll also inform you about some important FAA restrictions you may not know about.

Can you bring hair spray on a plane?

Yes, you can bring hair spray on a plane. If bringing hair spray as a carry-on you will need to make sure that your liquid or aerosol bottles are under 3.4 ounces.

If you are transporting hair spray in your checked luggage, you can bring larger canisters but you must still comply with FAA size-limit restrictions.

Aerosol versus pump hair spray

Most people probably use aerosol hair spray.

This is the type of pressurized canister that has a small nozzle on top which allows hair spray to be dispersed continuously in a cloud of spray.

Pump hair spray requires you to pump the nozzle in order for it to make its way out of the bottle. This type of hair spray should be treated as a true liquid since it is not an aerosol.

However, for purposes of carry-on and checked baggage TSA rules, it doesn’t really matter if you have an aerosol or pump hair spray.

The only major difference between the two is that aerosol cans will require that the button/nozzle is protected by caps or other suitable means to prevent accidental release.

Make sure you don’t blow off the requirement for a cap. It might seem like such a small requirement but in the past I have been forced to throw out aerosol cans because the cap was missing!

How to bring hair spray on a plane

When traveling on a plane, you will have to decide if you want to bring your hair spray in a carry-on or checked bag. Both are allowed by TSA.

Your carry-on bag comes with you on the plane which means that you will have your hair spray with you for the entire flight. The drawback is that your item is subject to the liquids rule which means you can only bring the smaller sized canisters.

If you bring hair spray in your checked baggage, you will not have access to it during your flight. However, you can bring larger cans in your checked baggage but there are still some FAA size restrictions which I will talk about below.

Putting hair spray in your carry-on

The first thing you need to know about bringing hair spray on a plane is that you’ll be subject to the TSA liquids 3-1-1 rule.

This rule states that your liquids must be contained within a container no larger than 3.4 fluid ounces or (100 mL) and that all of your liquid containers must fit comfortably within a quart sized, re-sealable bag.

A normal size bottle of hair spray will likely range from 8 to 12 ounces. This means that you cannot bring a normal size can of hair spray in your carry-on.

However, the good news is that you can find travel sized hair spray cans pretty easily.

You can buy TSA compliant bottles of shampoo which are basically just travel bottles of hair spray that come in containers smaller than 3.4 fluid ounces.

Some popular travel hair spray bottles include:

You will want to keep your hair spray in your luggage during your flight virtually all the time.

You absolutely do not want to spray your hair spray in the cabin.

The main reason is that because this is a confined space you could send those aerosols flying in the face of other passengers.

Some people can be very sensitive to chemicals and you could actually end up harming someone by spraying your hair spray at your seat.

Indeed, this is why the FAA tells passengers to “consult the flight crew before using items that give off strong odors or vapors.”

Spraying hair spray in the plane lavatory (bathroom) is a different matter.

Personally, I would try to avoid it if you are dealing with a small lavatory and flying economy.

The reason is that there are a lot of economy passengers and the odds of someone coming in right after you are pretty high — if you just sprayed a lot of hair spray, that could be a harsh experience for some passengers.

However, I have flown on some business and first class flights where there are larger lavatories and there were no issues with using hair spray in those.

Putting hair spray in checked baggage

If you want to put your aerosol hair spray in your checked baggage that is permitted but there are special restrictions on the quantity that you can bring.

Basically, the FAA outlaws hazardous materials on planes but they make exceptions for certain medicinal & toiletry items like: hairspray, hand sanitizers, aerosols, rubbing alcohol, inhalers, nail polish and remover, etc.

Below are the two restrictions you need to stick to your memory.

Individual hairspray container size limits

For checked baggage, the FAA states:

The capacity of each container must not exceed 0.5 kg (18 ounces) or 500 ml (17 fluid ounces).

(This limitation can also be found when searching the Department of Homeland Security (DHS).)

The hairspray size limit of 18 ounces or 17 fluid ounces is pretty generous.

As mentioned above, most hairspray containers probably range from 8 to 12 ounces so that gives you a bit of buffer.

Total amount of hairspray allowed

The FAA also has a limit for the total amount of hairspray that you can bring in your checked baggage.

This limit factors in all of the containers in your checked bag subject to this FAA hazardous materials exception.

So, for example, if you had hairspray and perfume in your checked baggage, you would add the size of those containers together and your total would need to be under the limits below.

They state:

The total aggregate quantity per person cannot exceed 2 kg (70 ounces) or 2 L (68 fluid ounces).

The aggregate limit of 68 fluid ounces means that you could probably bring about five to six cans of normal sized hair spray in your checked baggage but not much more than that.

Initially, I suspected that these FAA size-limit rules only applied to aerosol hair spray and not pump-action hair spray.

But if you take a look at the language used you will see that they include aerosol separate from hair spray:

Hairspray, hand sanitizers, aerosols, rubbing alcohol, inhalers, nail polish and remover, etc.

For personal use including aerosols, hair spray, perfumes, colognes, nail polish, rubbing alcohol, shaving cream, inhalers, medicines

Because they specifically list out hair spray separate from aerosols, it suggests that even purely liquid pump action hair spray is subject to this limitation.

Furthermore, they also include other pure liquid items like nail polish, alcohol, etc.

So if you are bringing non-aerosol hair spray you should abide by the above limitations.

The quantity limits are there for good reason.

Placing aerosol cans in the cargo hold of the plane code, under the right circumstances, could result in a catastrophic explosion.

Hair gel

Hair gel is another commonly asked about item related to hair spray. Gels are considered liquids for TSA which means that you will be subject to the same liquids rule above.

The best course of action is to purchase travel sized bottles of hair gel or simply pour your gel into containers no larger than 3.4 ounces.

There are special travel bottles you can buy online that are squeezable and better suited for gels than the bottles that cannot be squeezed.

I don’t see hair gel listed as a toiletry on the FAA restrictions above which makes me wonder if those quantity restrictions for checked baggage don’t apply.

It seems likely that the restrictions would apply based on the nature of the liquid so you may not be able to bring unlimited quantities of hair gel on a plane.

However, TSA does not state that these limitations apply to hair gel in checked baggage.

Dry shampoo

We have an entire article dedicated to the restrictions around bringing shampoo, including dry shampoo. The rules are very similar to bringing hair spray but you can check out the full guide here.
