Dyson Supersonic vs Revlon One-Step: is the splurge worth it?
One costs about ten times the other. Only one of them is a hair dryer in the normal sense.
This comparison gets framed as luxury versus dupe, which misses the point: these are two different tools. The Dyson Supersonic is a very fast, very controlled hair dryer. The Revlon One-Step is a hot air brush — a dryer and a round brush fused into one thing, designed to give you a blowout without coordinating two hands.
So the real question is not which is better. It is which job you are trying to do.

Side by side
| Dyson Supersonic | Revlon One-Step Volumizer | |
|---|---|---|
| What it is | A hair dryer with attachments. | A hot air brush — dryer and round brush in one. |
| Learning curve | You still need brush skills for a blowout. | Almost none. Section, roll, done. |
| Heat control | Measures air temperature many times a second to avoid heat damage. | Fixed heat settings. No active regulation. |
| Speed | Very fast drying, high airflow. | Slower — it is styling and drying at once. |
| Weight & balance | Motor sits in the handle, so it is well balanced but not light. | Light, but the brush head makes it bulky to manoeuvre. |
| Best hair type | All types, especially thick or long hair that takes forever to dry. | Fine to medium hair wanting volume. Struggles on very thick hair. |
| Longevity | Built to last, with a long warranty. | A consumable. Many people replace it every year or two. |
| Best for | Someone drying hair daily who values speed and heat protection. | Someone who wants a decent blowout with no technique. |

The two picks
Supersonic Hair Dryer
The dryer that reset expectations for the category. A small, fast digital motor in the handle instead of the head, which fixes the balance, plus heat measurement many times a second to keep the air from getting hot enough to damage hair. If you dry thick or long hair every day, the time saved is real and the heat protection is the actual argument for the price.
One-Step Volumizer Hair Dryer & Brush
One of the best-selling hair tools ever made, and deservedly. It merges the dryer and the round brush so you can get a bouncy, voluminous finish with one hand and no technique — the exact thing most people find impossible with a normal dryer. It is slower, hotter and less refined. It also costs roughly an eighth as much.
If you have never managed a decent blowout with a normal dryer, the Revlon will change your mornings and the Dyson will not — a better dryer does not give you brush skills. If you already blow-dry well, or you have thick hair and dry it daily, the Dyson buys you speed and genuine heat protection. They solve different problems, and owning both is not irrational.
Where the money actually goes
The Dyson premium is not marketing alone. Two things are real: the motor is small enough to sit in the handle, which changes how the tool balances in your hand over a long dry, and the dryer measures its own air temperature continuously to stop it running hot enough to cook your hair. On fine or colour-treated hair used daily, that matters over years.
What the price does not buy you is technique. A Dyson in untrained hands still produces a mediocre blowout, just faster.
Where the Revlon wins outright
The One-Step’s advantage is that it removes the hard part. Holding a dryer in one hand and rolling a round brush with the other is a genuine skill. Fusing them means anyone can section, roll and get volume at the root on the first try.
It is worth being honest about the trade: it runs hot, it is slower on thick hair, and it is a consumable — plenty of owners are on their second or third. At the price, most consider that acceptable.
If you want the Dyson result for less
There is no true Dyson dupe. The motor and the heat regulation are the product. What exists are good hot air brushes, of which the Revlon is the most proven. Buy it for what it is rather than as a substitute, and it is one of the best-value tools in the category.
FAQ
Is the Dyson Supersonic worth the money?
If you dry thick or long hair most days, the time saved and the heat regulation are real and compound over years. If you dry your hair twice a week, the honest answer is probably not — the gap in results is much smaller than the gap in price.
Is the Revlon One-Step a Dyson dupe?
No, and treating it as one leads to disappointment. It is a hot air brush, not a dryer. It competes with the Dyson Airwrap concept far more than with the Supersonic.
Does the Revlon One-Step damage hair?
It runs hotter and with less control than a premium dryer, so used daily on fine or bleached hair it can cause damage over time. Use the lower heat setting, keep it moving, and use a heat protectant.
Which is better for thick hair?
The Dyson. The One-Step struggles to dry very thick hair efficiently and you will spend a long time on it. Thick-haired users are the group who most often say the Dyson justified itself.
Can I use the Revlon on wet hair?
Rough-dry to about 80 percent first. Using it on soaking hair is slow and gives a worse result — this is the most common mistake people make with it.
