Can You Bring Hairspray on a Plane?
QUICK ANSWER
Yes, you can bring hairspray on a plane. In your carry-on, it follows the 3-1-1 rule, so the can or bottle must be 3.4 ounces or less and fit in your quart bag. In checked luggage, you can pack full-size hairspray up to 18 ounces per container with the cap protected.
Hairspray sits in a middle zone: it is a personal-care product, which keeps it allowed, but it is also usually an aerosol, which brings a few extra checked-bag limits. The rules are easy once you separate carry-on from checked. Here is how much hairspray you can bring and where to pack it.
Can you bring hairspray on a plane?
Yes, hairspray is allowed in both carry-on and checked baggage as a personal-care product. In your carry-on, the TSA liquids and aerosols rule applies, so the container must be 3.4 ounces (100 milliliters) or less and fit in your quart-size bag, whether it is an aerosol can or a pump bottle. For full-size hairspray, checked baggage is the answer, with some quantity limits that come from the FAA because most hairspray is flammable. Unlike truly hazardous aerosols such as spray paint, personal-care hairspray is permitted within these limits, so you are not choosing between carrying it and leaving it home; you are just choosing the right bag and size.
How much hairspray can you bring in your carry-on?
Travel-size only. To bring hairspray through the checkpoint, the can or bottle must be 3.4 ounces or less and fit in your single quart-size bag with your other liquids and gels. Plenty of brands sell travel-size aerosol and pump hairsprays made for exactly this. A full-size can will not pass security, even if it is mostly used up, because officers go by the container's labeled size. If travel-size hairspray is hard to find in your brand, a small non-aerosol pump bottle you fill yourself works too, as long as it is under the limit. Keep the cap on so it does not discharge against your other toiletries in the bag.
Can you pack full-size hairspray in checked luggage?
Yes, and this is where your regular can goes. The FAA allows personal-care and medicinal aerosols in checked bags with limits: each container can be up to 18 ounces (500 milliliters), and the total of all such aerosols cannot exceed 70 ounces (about 2 kilograms) per passenger. The release nozzle must be protected by its cap or another means so it cannot spray by accident. A standard can of hairspray falls well within the 18-ounce limit, so a full-size can is fine to check. Just keep the cap on and pack it upright among soft items, since pressure changes in the hold can stress an unprotected nozzle.
Does aerosol versus non-aerosol hairspray matter?
For your carry-on, no; for checked bags, a little. Both aerosol and pump (non-aerosol) hairspray follow the same 3-1-1 rule in the cabin, so either type must be 3.4 ounces or less in your quart bag. The difference shows up in checked luggage: aerosol cans fall under the FAA's 18-ounce-per-container and 70-ounce-total aerosol limits with a protected cap, while a non-aerosol pump bottle is treated as an ordinary liquid with no size limit in checked bags. So if you want to check a very large bottle, a pump hairspray gives you more room. For most travelers, a travel-size can in the carry-on or a standard can in the checked bag covers the trip.
Yes, you can bring hairspray on a plane. In your carry-on it follows the 3-1-1 rule, so it must be 3.4 ounces or less in your quart bag. Full-size hairspray goes in checked luggage, where aerosol cans are allowed up to 18 ounces each with the cap protected. Pump bottles have no size limit when checked.
