The Dyson Travel Hair Dryer, Ten Years After Project Lion

The Dyson travel hair dryer is a smaller, lighter Supersonic that switches voltage on its own, so it works almost anywhere you land. Here it is next to other travel dryers and mini hot tools, plus a small carry-on hair kit.

A Dryer in a Silver Briefcase

The first Dyson hair dryer was a secret carried around in a padlocked silver briefcase. Vogue UK reported that the prototype was code-named Project Lion, and Dyson says it took 50 months, 103 engineers and 600 prototypes to make the Supersonic. It launched in April 2016, and the big idea was putting the motor in the handle instead of the head.

Ten years later, Dyson made it smaller. The Supersonic Travel launched on April 20, 2026 in select markets, according to Dyson's own announcement. It is 32% smaller and 25% lighter than the full-size Supersonic, weighs 331 grams without attachments, and runs on 100 to 240 volts, so you do not need a converter abroad.

That last part is why people search for a Dyson travel hair dryer in the first place. Hotel dryers are weak, bolted to the wall and often broken, and a full-size dryer eats half a carry-on.

The first grid is the Dyson with five other travel and folding dryers, plus two mini hot tools for smoothing and curling. The second grid is a small carry-on hair kit: rollers, a brush, heat protection, dry shampoo and oil.

A packing tip: before you leave, check the voltage printed on every hot tool you own. Dual voltage tools switch on their own. Single voltage tools can burn out on a foreign socket, even with an adapter plug.

Travel Dryers and Two Mini Tools

Every dryer here is made to travel, but they are good at different things.

The Dyson Supersonic Travel is the one with the most engineering behind it, and the automatic voltage is the feature I care about most. If you already love the full-size Supersonic, this is the same idea in a bag-friendly size.

The T3 Afar is the other auto dual voltage pick, light and travel-size. Drybar Baby Buttercup is tested, the brand says, to deliver 100 percent of the power of most full-size professional dryers. Mane This Totally Blows is an ionic compact dryer made for frizz-free blowouts. Curlsmith Defrizzion comes with a large diffuser, so it is the one for curls, coils and waves. Shark Beauty SpeedStyle Pro FLEX folds, which is the trick for packing a stronger dryer into a smaller space.

Then two tools for finishing. BondiBoost Mini is one base with two attachments, a straightening brush and a curling iron. Drybar The Baby Brush Crush is a mini heated brush that smooths in one step.

What I would skip: the Shark if you travel carry-on only and pack tight. It folds, but it is still a full-power dryer, and it takes up more room than the compact ones.

A Carry-On Hair Kit

This is the kit I would pack around the dryer. Everything is mini, so it clears a liquids bag.

Mane Roll and Scroll Self-Grip Rollers are six heat-free rollers. Put them in while you do your makeup, take them out before you leave the room, and you get body without a round brush. The Mane Mini Detangling Brush is small enough for a clutch.

Heat protection comes first, always. Moroccanoil Mini Perfect Defense is a weightless heat protectant, and Drybar Mini Hot Toddy is a mist that protects and leaves a smooth finish. Pick one and spray it on damp hair before any dryer touches it.

For second-day hair, Living Proof Mini PhD Dry Shampoo absorbs oil and adds body, and OUAI Mini Melrose Place is a super dry, invisible formula. Spray it at night before bed, and it will have soaked up the oil by morning.

Two oils finish the kit. Moroccanoil Treatment is the original, and the brand says it detangles, speeds up drying and adds shine. Gisou Honey Infused Hair Oil smooths frizz and flyaways, and it smells faintly of honey.

What I would skip: packing both oils. A few drops is all you need on a trip, so one small bottle lasts the whole week.

Pack the Voltage, Not the Weight

I think the best argument for a Dyson travel hair dryer is not speed or shine but simplicity. One dryer that works in every country means one less thing to think about at the airport. Pair it with one heat protectant, one dry shampoo and one oil, and you have a hair kit that fits in the corner of a carry-on. The first Supersonic traveled in a locked briefcase. Yours can go in a shoe bag. If you want to keep browsing, I also put together Dyson Supersonic r Hair Dryer and The Best Hair Dryer for Your Hair Is Not Always the Newest One.
