I once did a full blow dry the morning of a nine hour flight. Straightened it, everything. By the time I landed it was flat on one side, frizzy on the other, and slightly greasy at the roots.
Nine hours of dry recycled air and a headrest will do that to anyone. And I had done nothing to protect against either.
So here are the twelve styles I actually use now, sorted roughly from short haul to long haul. Number four is the product habit that made the biggest difference for me, and it takes thirty seconds.
What flying actually does to your hair
Cabin air sits at around ten to twenty percent humidity, which is drier than most deserts. Your hair loses moisture through the whole flight, which is why it feels straw-like and static by the time you land, and why curls in particular go frizzy and undefined.
Then there is friction. Anything resting against a headrest for hours gets flattened and roughed up, which is why the back of your head always looks worse than the front. That is the reason every style on this list either lifts the hair away from the seat or is loose enough not to hold a dent.
1. Loose low bun at the nape

The most comfortable option for a long flight because it sits low enough to lean back against without a lump digging into your skull. Twist rather than braid, secure with a claw clip rather than an elastic, and it comes out with soft waves instead of a hard kink.
2. Two loose plaits

Sounds childish and it is genuinely the best thing for hair that gets frizzy. Braid loosely, secure at the ends only, and you land with soft waves and no tangles. Do them on slightly damp hair with a little leave in conditioner and it doubles as a treatment.
3. Silk scrunchie, never a thin elastic
Small swap, real difference. Thin elastics with a metal join dig in over hours and leave a permanent dent plus breakage where they sit. A silk or satin scrunchie spreads the tension and slides out without pulling. Worth about five pounds and it lasts years.
4. Apply a leave in oil before you leave the house

Here is the habit that changed my landings. A small amount of light oil or leave in cream through the mid lengths and ends before you set off, so it works against the dry air for the whole flight. Not on the roots, since that goes greasy under a headrest.
5. Half up claw clip

For short haul where you want to look reasonably normal on arrival. Twist the top section up into a medium claw clip, leave the rest down. It keeps hair off your face through security and takes about four seconds to redo before you land.
6. High bun, only if it is not a headrest flight

A proper high bun looks tidy and it is impossible to lean back against. So it is great for a two hour hop where you will be sitting upright, and miserable on an overnight. Ask yourself whether you plan to sleep before choosing this one.
7. Braided crown or a wrapped headband braid

A braid taken across the top of the head and pinned behind the ear. It keeps everything secured without any bulk at the back, so you can lean back comfortably. Use two crossed grips rather than one, since a single pin works loose over a long flight.
8. Silk scarf tied over the length

Wrap a silk scarf around a low ponytail or over the whole length. It protects against friction and static, and it looks deliberate rather than like you have given up. Silk rather than cotton, because cotton grips the hair and causes exactly the breakage you are trying to avoid.
9. A cap over unwashed hair

There is no shame in this. Day three hair under a plain cap, with the length in a loose plait out the back. Do not put a hat over a fresh blow dry though, since the pressure line at the forehead is impossible to fix without rewashing.
10. Sleek low ponytail with a wrapped section

For anyone arriving straight into something. Smooth it back with a little cream, secure low, then wrap a thin section around the elastic and pin it underneath. It survives a flight far better than anything voluminous because there is nothing to flatten.
11. Protective styles for textured hair

Braids, twists or a silk bonnet over a loose style. Dry cabin air is particularly harsh on coily hair, so moisturise well before you fly and cover if you can. A large satin bonnet under a hood on an overnight flight is not glamorous and it works.
12. Pack a two minute fix kit

A small pouch with a scrunchie, two grips, a travel dry shampoo under 100ml, and a folding brush. Ten minutes before landing, redo whatever has collapsed. That tiny window is the difference between arriving looking tired and arriving looking fine, and it costs almost nothing.
How to choose based on your flight
Match the style to the flight length and whether you plan to sleep. Anything under three hours where you stay upright, you can wear a high bun, a claw clip or a ponytail without issue. Anything over six hours, or an overnight, needs to be low and soft, because you will lean back and whatever you are wearing will get pressed flat for hours.
Then think about what happens on arrival. If you are going straight from the airport to see people, choose something that improves as it comes out, so loose plaits or a twisted bun that leaves waves rather than a style that just collapses. And prep matters more than the style itself: hair that is properly moisturised before boarding lands in a completely different condition to hair that is not. I now put oil in at home rather than packing it, because a bottle in the hold does absolutely nothing for you at 35,000 feet, which took me an embarrassing number of flights to work out.
Frequently asked questions
What is the best hairstyle for a long haul flight? A loose low bun or two loose plaits, secured with a silk scrunchie or a claw clip. Both sit low enough to lean back against comfortably and neither leaves a hard dent after several hours.
Why does my hair get so frizzy on planes? Cabin humidity sits around ten to twenty percent, which is drier than most deserts, so hair loses moisture throughout the flight. A leave in oil or cream applied before boarding is the most effective protection.
Should I wash my hair before flying? Ideally the day before rather than the morning of. Freshly washed hair goes flat and greasy faster under a headrest, while day two hair holds a style better and copes with the dry air more comfortably.
Can I take dry shampoo on a plane? In hand luggage it needs to be under 100ml and inside your liquids bag, since aerosols count as liquids. A powder dry shampoo avoids the issue entirely and takes up less space.
How do I protect curly hair on a flight? Moisturise well before boarding, wear it in twists or a loose protective style, and cover with a satin bonnet or scarf. Cotton headrests and dry air are the two things that undo curl definition fastest.
Final thoughts
Airport hair is one of those small things that has an outsized effect on how the first few hours of a trip feel. Arriving already a bit dishevelled sets a tone I would rather avoid.
If you are flying soon, try the oil before you leave and a silk scrunchie instead of your usual elastic. Two tiny changes, neither costs much, and they will probably do more for how you land than any style on this list.
