Revlon One-Step Volumizer Plus: What the Specs Say
The cheapest tool we cover carries the longest warranty of anything in our registry. That is worth explaining.
Updated September 2026 · Sawyer V.
Revlon publishes four heat settings — low, medium, high and cool — a ceramic titanium barrel with tourmaline ionic technology, a detachable brush head and a four-year limited warranty. That warranty is double what Dyson, Shark and T3 publish on anything.

The number that stands out
Four years of limited warranty. Dyson publishes two on the Supersonic, two on the Airwrap and two on the Corrale. Shark publishes two on everything. T3 publishes two. ghd publishes three, and it is the longest warranty on any premium tool we list.
The cheapest kind of tool on this site carries the longest written durability commitment on it, by a full year over the nearest premium competitor and by double over the flagships.
A warranty is not a lifespan measurement and we are not going to pretend it is one. It is a commercial decision priced against expected failure rates and the cost of honoring claims — and replacing a cheap tool costs a company far less than replacing an expensive one, which may be the whole explanation. But it is the only durability figure any of these companies puts in writing, and this one is not on the expensive shelf.
Everything Revlon publishes
- Four heat settings — low, medium, high and cool. More heat granularity than the T3 AireBrush publishes.
- Ceramic titanium barrel with tourmaline ionic technology.
- Detachable brush head — the published difference between this and the older Salon One-Step.
- Four-year limited warranty.
And what they do not publish: wattage, weight, cord length, speed setting count, voltage. That is five blank rows in the standard spec block, more than any other product in our registry. It also means no running cost can be computed for this tool.
What the detachable head is actually for
Revlon publishes it as the difference between this and the older Salon One-Step, and it is more consequential than a spec line suggests. A hot air brush pulls hair through heated bristles, so it accumulates shed hair and product residue faster than any other tool in this category.
Residue on a heated barrel bakes on and changes how heat transfers. Hair packed into bristles reduces grip. A head that comes off is a head you can actually clean — and over a four-year warranty period, that is the difference between a tool that still works properly in year four and one that quietly stopped a while ago.
Who it suits
- Fine hair that goes flat. This is the tool’s strongest case, and the four heat settings with a cool option support it — the fine-hair page.
- Anyone who wants a blowout without the technique. One hand instead of two.
- Anyone weighing an air styler. If what you actually want from an Airwrap is smooth volume rather than defined curls, this does that part for a small fraction of the price — the dupe comparison.
Who should skip it
- Anyone who wants genuinely straight hair. This is a smoothing and volumizing tool, not a straightening one.
- Anyone with tight curl patterns. The barrel may be too small to stretch effectively — the curly-hair page.
- Anyone who needs to check the specifications before buying. Five blank rows is five things you cannot verify, and on fragile hair that is a real limitation.
What we cannot tell you
We have not used it. We do not know its wattage, weight or cord length, because Revlon does not publish them. We cannot compute what it costs to run for the same reason. And we have no view on how well it performs relative to anything else, because we have not tested any of these.

Price per use, at 5 uses a week over 5 years
| What you pay | Cost per use | Cost per year |
|---|---|---|
| $30 | $0.02 | $6.00 |
| $60 | $0.05 | $12.00 |
| $100 | $0.08 | $20.00 |
| $150 | $0.12 | $30.00 |
| $200 | $0.15 | $40.00 |
| $300 | $0.23 | $60.00 |
| $400 | $0.31 | $80.00 |
| $500 | $0.38 | $100.00 |
5 uses a week for 5 years is 1300 uses. Both figures are stated assumptions, not measurements — halve the life and every cost per use doubles. We publish the ladder rather than a worked example for one specific product because a price we typed into a sentence would be wrong within a week.
The tools on this page
Prices come from the live price layer. Where none is available the button says so rather than showing a number we cannot stand behind.
Revlon One-Step Volumizer Plus hair dryer and hot air brush
A 4-year limited warranty, the longest in this registry, on the cheapest kind of tool in it. Worth noticing before paying six times more elsewhere.
T3 AireBrush One-Step smoothing and volumizing dryer brush
Six heat-and-speed combinations against the Revlon's four heat steps, and a published weight — but half the warranty.
Questions people actually ask
How long is the Revlon One-Step warranty?
Revlon publishes a four-year limited warranty on the One-Step Volumizer Plus, which is double what Dyson, Shark and T3 publish on any of their tools and a year longer than ghd's three.
What is the difference between the Revlon One-Step Volumizer Plus and the original?
Revlon publishes two differences: the Plus has a detachable brush head where the original does not, and the Plus states four heat settings where no count is published for the original. Both carry the same four-year limited warranty.
How many watts is the Revlon One-Step Volumizer Plus?
Revlon does not publish a wattage on the product page, which also means no running cost can be computed for it. We do not fill that row in from retailer listings.
Is the Revlon One-Step a good Airwrap alternative?
For smooth, voluminous blowouts yes, at a small fraction of the price. It will not wrap hair around a barrel to set a curl, so it is a different tool rather than a cheaper version of the same one.
