💈 Aerosol spray (hairspray, deodorant)

A full-size aerosol can over 100ml will be confiscated at the checkpoint because aerosols are treated as liquids under carry-on rules. This applies to hairspray, spray deodorant, dry shampoo, and any other non-hazardous aerosol. Travel-size cans of 100ml or less fit in your clear liquids bag and pass through without issue, as do stick and roll-on deodorant formats which have no size restriction at all.

The 100ml carry-on limit for non-hazardous aerosols such as hairspray and deodorant is consistent across all 14 regions we cover. Aerosols labeled as hazardous materials — such as spray paint, insecticides, or flammable industrial sprays — are banned from both carry-on and checked baggage in all regions. Standard personal care aerosols are fine in checked baggage in any quantity as long as the cap is secured.

Screeners look at the label and any HAZMAT symbols on the can. A standard consumer hairspray or deodorant has no HAZMAT markings and passes without issue. If a can has flammability warnings, hazard pictograms, or industrial labeling, officers can and will remove it. Stick to name-brand personal care products in their original packaging and you are unlikely to face any questions.

Always replace the cap securely on any aerosol before packing it in your checked bag, since caps prevent accidental discharge during handling. Seal the aerosol in a zip-lock bag as an extra precaution in case the nozzle is activated by pressure or impact. There is no stated quantity limit for personal-use aerosols in checked baggage, but most airlines follow IATA guidance capping personal care aerosols at 0.5kg or 500ml per can.
