Planning to bring sprays on your international trip but not sure if they’re allowed on planes? Can you bring hair spray on a flight? What about pepper spray?
Today, the Trip.com team is here to answer them one by one about everything you might wonder while packing your bags for a flight. Come along and take a look!
The short answer is yes but not all sprays are allowed.
Common personal care sprays like facial mists, toner sprays, makeup setting sprays, and similar everyday products are usually allowed on flights, provided they meet airport security requirements.
If you’re carrying them in your hand luggage, these sprays are treated as liquids, so you’ll need to follow standard cabin baggage rules:
This applies when departing from airports like Singapore Changi Airport as well as most international airports.
Some spray products are considered more restricted, especially aerosols labelled with a flammable symbol (🔥).
If your spray bottle has a flammable warning label, it may be allowed in carry-on luggage, even if it’s under 100ml as long as they are for personal use (e.g. hairspray, deodorant).
Yes, but there are restrictions.
If you want to bring sunscreen spray in your carry-on bag:
If the sunscreen spray has a flammable aerosol warning symbol (🔥), it may be allowed in cabin baggage.
Make sure it is under 100ml if it is in carry-on.
When in doubt, pack it in your checked luggage instead.
Yes, but checked baggage usually allows more flexibility👇
As long as your sunscreen spray contains safe, non-hazardous ingredients and is in compliant packaging, you can pack it in your checked bag.
Even aerosols labeled as flammable can usually go in your checked baggage, as long as they meet the "personal-use aerosol" rules set by civil aviation authorities and your airline:
✔ For personal care, grooming, or hygiene use only (e.g., sunscreen, antiperspirant, hairspray)
✔ Each container must not exceed 500ml or 0.5kg
✔ Total aerosol products must not exceed 2L or 2kg per passenger
✔ The bottle must have a safety feature to prevent accidental activation (such as a nozzle cap).
❌ Not permitted for industrial or cleaning purposes (such as insecticides or spray paint)

Sure, but please confirm the "type" and "capacity" first.
When checking your bags, please keep the following restrictions in mind:
More Info
The answer is no.
Pepper spray is generally not prohibited in both:
Many airports and countries classify pepper spray as a controlled weapon.
This includes destinations such as Hong Kong and Macau, where strict penalties may apply if prohibited items are discovered. To avoid delays, fines, or confiscation, leave pepper spray at home.
Buying spray products at duty-free shops? Keep these tips in mind:
If you’re transiting through airports especially in Europe duty-free liquids and aerosols often need to remain sealed in the official tamper-proof bag.
If you open the bag during transit, airport security may confiscate the item during your next screening.
The safest option? Buy duty-free sprays after clearing your final security checkpoint.
If you’re flying from Singapore Changi Airport, always double-check both airline baggage policies and destination customs rules before packing spray products.
When unsure, pack non-essential aerosols in checked luggage or skip them entirely for a smoother airport experience.
