Planning your next adventure and wondering, “Can you bring hairspray on a plane?” Whether you’re jetting off to Singapore, flying with AirAsia, or boarding any international flight, here’s everything you need to know about packing hairspray and aerosols safely and legally.
Carry-On Rules for Hairspray
The 100 ml Rule
Yes, you can bring hairspray in your carry-on luggage — but it must comply with the standard liquids, aerosols, and gels (LAGs) rules:
- Each container must hold no more than 100 ml (3.4 oz)
- Even a partially full can must still meet this size limit
- All LAGs must fit inside a single transparent, resealable plastic bag (approximately 20 cm × 20 cm, no more than 1 litre total capacity)
- Larger cans must go in your checked baggage
How Many 100 ml Bottles Can You Take in Hand Luggage?
You may pack as many 100 ml containers as fit comfortably inside one one-litre clear zip-top bag. Each container must individually hold no more than 100 ml of liquid, gel, or aerosol. The bag must seal properly without being overfilled.
Hairspray on AirAsia Flights
AirAsia follows the standard LAGs policy. Hairspray is permitted in carry-on if:
- The container is 100 ml or less
- It is placed in your clear, resealable plastic bag alongside other liquids and gels
Hairspray on Flights to/from Singapore
Singapore’s Changi Airport enforces the same international standard:
- Each aerosol container: 100 ml maximum
- Total carry-on liquids bag: no more than 1 litre
- Bag must be transparent and resealable

Checked Baggage and Aerosol Rules
Can You Pack Hairspray in Checked Luggage?
Yes. Full-size aerosol products — including hairspray, deodorant, sunscreen, shaving foam, and hair mousse — are generally permitted in checked baggage. Pack them securely to prevent accidental discharge.
Non-Flammable Aerosols in Checked Baggage
Non-flammable aerosol canisters are allowed in checked luggage. Before packing, check that:
- The can does not display a flammable hazard symbol (red diamond)
- The contents comply with your airline’s quantity limits
Aerosols on International Flights
The standard international rule applies:
- Each aerosol: 100 ml or less in carry-on
- In checked baggage: full-size non-flammable aerosols are generally permitted
- Always verify limits with your specific airline before travel, as restrictions can vary by country
What Aerosols Are Not Allowed on Planes?
The following aerosols are prohibited in both carry-on and checked luggage due to flammability or safety risks:
- WD-40
- Spray paint
- Spray starch
- Cooking sprays
- Any aerosol not classified as a medicinal or toiletry product and displaying a flammable hazard sign
Other Common Travel Packing Questions
What Is Not Allowed in Checked Baggage?
The following are prohibited in checked luggage regardless of size:
- Firearms, ammunition, and replicas (without prior airline approval)
- Fireworks and explosive materials
- Petrol and highly flammable liquids
- Toxic chemicals and pesticides
- Improperly packaged lithium batteries
Does Toothpaste Count as a Liquid?
Yes. Transportation security classifies toothpaste as a liquid. It must follow the same LAGs rules as hairspray, perfume, and aerosol deodorant — 100 ml maximum per container, packed in your single clear resealable bag.
Is Hairspray Flammable?
Many hairsprays contain flammable propellants and solvents. While permitted on flights in travel-sized containers, avoid using hairspray near open flames or heat sources. Always check your airline’s specific guidelines before travelling with aerosol personal care products.
Conclusion
Yes, you can bring hairspray on a plane. Keep it in a container of 100 ml or less, pack it in your clear resealable LAGs bag for carry-on, or stow a full-size can in your checked luggage. Following these straightforward rules means no hold-ups at security and no surprises at the gate.
