One more change of direction
Drew opened a page of new Airwrap sets and paused. The original handle still worked. Replacing it felt premature, even with the two curling barrels beginning to get on Drew’s nerves.
Drew’s old US HS01 had separate barrels for clockwise and counterclockwise curls. Drew liked alternating adjacent sections of below-shoulder hair, which meant repeatedly exchanging one barrel for the other.
Doing all the sections that needed the same direction together would reduce the exchanges. That was a reasonable way to keep using the pair. Drew wanted to keep the chosen section order, though, and went looking for the small control visible on newer barrels.
The handle can stay
The control was a rotating cool tip. On Dyson’s 1.6 inch long barrel in Black/Rosé, it selected either direction through the same attachment. That suited Drew’s taste for a physical control with a clear job.
Compatibility took a closer look. Dyson’s first-generation upgrade announcement explicitly allowed owners to retain their original machine. Its current Airwrap i.d. guidance says the new attachments work with previous Airwrap devices. Together with the exact barrel’s place in that range, those statements support keeping Drew’s HS01.
There is a newer boundary to watch. Co-anda2x has a separate attachment system. A Co-anda2x barrel is unsuitable for this older handle, even though the Airwrap name appears on both.
Drew chose the genuine Dyson 1.6 inch long barrel in Black/Rosé. Dyson identifies it as part 974158-01. The linked Amazon listing matches the brand, diameter, long format, color and single-barrel package, but does not display that part number. Check those details and the current seller before ordering, especially when moving between variants or similar-looking accessories.
Keep the familiar routine around it
Drew already had the pre-styling dryer, comb, clips and filter brush. The 1.6 inch diameter was a deliberate choice for the long hair and style Drew wanted. Someone wanting another diameter or length would need to choose that accessory separately.
The new control would remove exchanges made solely to reverse direction. Preparation and care would continue. Secure the attachment, pre-dry before curling, use the cool tip and switch the appliance off to release the hair. Other parts of the attachment can be hot and need to cool before handling.
The original US handle also keeps its own instructions. Use it away from water on a suitable US supply, without an extension cord or voltage converter, and carry out the manual’s ALCI safety-plug check before each use. Unplug after use. For filter care, unplug and cool the appliance, keep water off the filter mesh and dry the washed cage before refitting it.
Drew checked the accessory against the personal budget, then closed the page of replacement sets. The old handle would stay.
When this does not matter
Your existing barrel already switches direction, or you are happy grouping sections by direction so that swapping the old pair is a minor part of the routine.
The practical fix
- Confirm that you have the original US HS01 with a working attachment lock, cord and plug. A new barrel is not a repair for a faulty handle or lock.
- For this long-hair, 1.6 inch choice, select the genuine Dyson Black/Rosé long barrel, manufacturer part 974158-01. The linked ASIN is B0FWMK35MG. Amazon does not show the part number, so check brand, size, long format, color, single-barrel package, seller and total. Exclude Co-anda2x and third-party lookalikes.
- Follow the HS01 manual for its suitable US power supply, dry location, ALCI check and clean, dry, fitted filter cage. Do not use an extension cord or voltage converter.
- Secure the attachment and pre-dry before curling. Use the rotating cool tip to choose direction between sections. Switch off to release hair, allow hot parts to cool before handling and unplug after use.
This applies if…
- You own a working original US Airwrap HS01, want a 1.6 inch long barrel and regularly alternate direction between sections.
- You want to retain the handle and continue its normal preparation, handling and filter care.
The answer changes if…
- The handle or attachment lock is faulty, or the accessory is for Co-anda2x.
- Your hair length or preferred style calls for another barrel size or format.

What to check in your own setup
- This upgrade removes barrel exchanges made solely to change direction. It does not establish faster styling, longer-lasting curls, better results or less heat damage.
- The compatibility conclusion combines Dyson’s exact accessory information with its current previous-device guidance and first-generation upgrade announcement. The exact parts page does not separately list HS01.
- The Amazon identity match uses the displayed brand, size, length format, color and package. Its manufacturer part number is absent. Price, seller and availability may change.
- Match the Dyson Airwrap 1.6 inch long barrel listing to model Manufacturer part 974158-01. Variant: Black/Rosé, one long barrel attachment for the earlier Airwrap and i.d. attachment system.
