What Toiletries Can You Take on a Plane?

That moment at security when you suddenly wonder whether your toothpaste counts as a liquid is exactly why travellers ask what toiletries can you take on a plane. The rules are manageable once you know them, but they do catch people out - especially if you are travelling with hand luggage only and every item has to earn its place.

For most UK travellers, the real issue is not whether toiletries are allowed at all. They are. The issue is how they need to be packed, which items count as liquids, and when it makes more sense to swap full-size products for travel-size versions. If you get that right, you save time at security, avoid having items removed, and make better use of limited cabin bag space.

What toiletries can you take on a plane in hand luggage?

You can take most everyday toiletries on a plane in hand luggage, including toothpaste, shampoo, conditioner, shower gel, moisturiser, deodorant, sunscreen, face wash, mascara and shaving gel. The catch is that many of these are treated as liquids, even when they do not look especially runny.

Under standard airport security rules, liquids in hand luggage usually need to be in containers of no more than 100ml each. They also need to fit inside a single clear plastic bag of around 20cm x 20cm, with a total capacity of about one litre. That means your toiletries can be perfectly allowed but still not permitted through security if the bottle is too large or the bag is overfilled.

This is where people often get caught out. A half-used 200ml bottle is not acceptable just because there is less than 100ml left inside. Security looks at the container size, not how much product remains. If the bottle says 200ml, it is too large for cabin liquids.

It is also worth remembering that airport rules can vary slightly by airport, particularly as some UK airports are introducing new scanners. Even so, it is safest to pack as though the standard 100ml rule applies unless your departure airport clearly states otherwise.

Which toiletries count as liquids?

This is the part that causes the most confusion. In airport security terms, liquids include more than obvious fluids. Creams, gels, pastes and aerosols are usually included too.

That means products such as toothpaste, liquid foundation, moisturiser, lip gloss, hair gel, face serum and roll-on deodorant all count as liquids. Mascara does too. So does shaving foam. If it can be squeezed, sprayed, spread or poured, there is a good chance security will treat it as a liquid.

Solid toiletries are much simpler. A bar of soap, solid deodorant stick, lipstick, powder make-up, make-up wipes and solid shampoo bars are generally easier to pack because they do not fall under the same liquid limits. If you are trying to travel light, switching some products from liquid to solid can make a noticeable difference.

There is a practical trade-off, though. Solid toiletries are useful for compliance and space-saving, but not everyone wants to change products just for a short trip. Many travellers would rather take familiar brands in the correct travel sizes and avoid the risk of leaking, overpacking or buying the wrong thing in a rush.

Common toiletries and whether you can take them

Most standard personal care items are allowed on a plane, but how you pack them matters.

Shampoo, conditioner and shower gel are allowed in hand luggage if each container is 100ml or under. The same goes for face wash, body lotion, sunscreen and perfume. Toothpaste is also allowed, but it must follow the liquid rules. Deodorant is usually fine, whether it is aerosol, roll-on or stick, though aerosols should still be travel-size for cabin bags.

Razors are a slightly separate issue. Disposable razors and cartridge razors are usually allowed in hand luggage. Traditional razor blades are more restricted and are better packed in hold luggage if you are unsure. Nail scissors and tweezers are often permitted if small, but security staff have final discretion, so it is sensible to keep anything sharp to a minimum.

If you use contact lens solution, that also counts as a liquid. Essential medication and baby items can follow different rules, but for standard toiletries the safest approach is still small containers, one clear bag, and only what you genuinely need.

What toiletries can you take on a plane in hold luggage?

If you are checking in a suitcase, the rules are more relaxed. You can usually pack full-size toiletries in hold luggage, including larger bottles of shampoo, conditioner, body wash, deodorant and other personal care items.

That said, hold luggage creates its own problems. Bottles can leak under pressure, lids can loosen, and heavy toiletries take up more weight and space than people expect. If you are paying extra for a checked bag, that may not matter much. If you are trying to keep luggage costs down, full-size toiletries can become expensive dead weight.

For short breaks, cabin-approved toiletries are often the more practical option even if you do have hold luggage. You avoid unpacking oversized bottles, you waste less product, and you are not carrying a week’s worth of shampoo for a two-night stay.

How to pack toiletries without problems at security

Packing toiletries well is less about clever hacks and more about keeping things simple. Choose travel-size versions of the products you actually use. Check every container size before you pack. Put liquid items together in a clear bag before you leave home rather than trying to sort them at the airport.

It also helps to be realistic about what you need. For a weekend break, you probably do not need a full skincare shelf in your cabin bag. A few essentials usually cover it: toothpaste, deodorant, face wash, moisturiser, shampoo and anything trip-specific like sunscreen or shaving products.

Pre-packed travel toiletry kits can make this much easier because they remove the guesswork. Instead of buying separate miniatures, decanting products into unlabelled bottles or discovering that your deodorant is too large at the last minute, you start with items already chosen for airport compliance and short-trip convenience. That is particularly useful for business travel, couple breaks and carry-on-only holidays where time and space are limited.

Hand luggage only? Focus on space as well as rules

When people ask what toiletries can you take on a plane, they are often really asking how to pack enough without wasting space. Compliance matters, but so does practicality.

Bulky bottles are not the only problem. Random single items take up more room than you expect and make packing feel disorganised. A proper travel-size set keeps everything proportionate to the length of your trip. That matters when your airline cabin bag allowance is tight and every centimetre counts.

There is also a convenience factor that should not be ignored. Hunting down travel minis in different shops, only to end up with mismatched products you would not normally buy, is not a great use of time. Familiar brands in cabin-friendly sizes are usually the easiest option because they let you pack quickly and travel with confidence.

A few grey areas worth knowing about

Not every toiletry decision has a single answer. Aerosols are generally allowed in hand luggage if they meet size rules, but some travellers prefer to avoid them because they take up liquid bag space quickly. Dry shampoo can be useful, but again, it usually counts towards your liquid allowance if it is aerosol.

Make-up can be mixed. Powder products are usually straightforward, while liquid foundation, cream blush and concealer go in your liquids bag. If you are unsure, pack it as a liquid. That is usually the safer call.

If you are travelling from different airports on the way out and back, it makes sense to follow the stricter interpretation. It reduces the chance of confusion, especially on return journeys when you are packing in a hotel room and trying not to forget anything.

The easiest rule of thumb is this: if a toiletry can spill, smear, spray or squeeze, treat it like a liquid. If it is solid and dry, it is generally easier to carry.

The practical answer most travellers need

So, what toiletries can you take on a plane? Almost all the essentials, provided they are packed correctly. In hand luggage, keep liquids to 100ml or less per container and place them in a clear bag. In hold luggage, full-size products are usually allowed, but they take up more room and can leak.

For most short trips, the best setup is simple: take only the toiletries you will actually use, keep them cabin-approved, and avoid repacking where possible. That is the difference between arriving at security feeling organised and standing there trying to explain why your half-empty 200ml shampoo should be fine.

If your goal is to get through the airport with less hassle, less waste and no last-minute packing doubts, the right toiletries are not just the ones you are allowed to take. They are the ones already sized, sorted and ready to
