TL;DR
- The Revlon One-Step Volumizer combines a hair dryer and an oval round brush to dry and style in one step (Ulta, 2026).
- It has 1100 watts, ionic technology and heat/speed settings with a cool option; exact settings vary by model (Ulta, 2026; Do it Best, 2026).
- Nylon pin and tufted bristles help detangle and give volume at the roots (Ulta, 2026).
- The US model is made for 120V outlets only, and Revlon does not recommend a voltage converter (Ulta, 2026).
- Bottom line: a fast, easy way to get a salon-style blowout at home; buyers outside the US should get the local-voltage model.

What Is the Revlon One-Step Volumizer?
The Revlon One-Step Volumizer is a hot air brush. It looks like a large oval round brush with a hair dryer built into the handle. Revlon describes it as giving the power of a dryer with the volume of a styler, so you can dry and style your hair in one pass (Ulta, 2026).
The first version was released in 2016, and Revlon later added newer models (iFixit, 2022). It remains one of the best-selling hair tools online.

What Stands Out
Oval brush shape
The flat sides of the oval smooth the hair, while the rounded edges create volume at the root and curve at the ends in a single pass (Ulta, 2026). This is what makes the result look like a salon blowout.
Can sit closer to the scalp
Revlon says that, unlike a normal hair dryer, the volumizer can be placed closer to the scalp for lift (Ulta, 2026). This is how it creates root volume.
Ionic technology
A built-in ion generator helps hair dry fast and helps reduce heat damage, according to Revlon (Ulta, 2026). Ionic air also helps reduce frizz and static (Do it Best, 2026).
Detangling bristles
The mix of nylon pins and tufted bristles helps detangle and grip the hair for volume and control (Ulta, 2026).
Important Voltage Warning
Revlon states that the US model is designed for 120V outlets only, and that it does NOT recommend a voltage converter because it will damage the unit (Ulta, 2026). Many countries, including much of Asia, Europe and Africa, use 220 to 240V. If you live outside the US, buy the version sold for your country's voltage rather than the US model from Amazon.com.
Who Should Buy It and Who Should Skip It
Good fit: medium to long hair, people who struggle to blow dry with a separate brush, and anyone who wants volume and smooth ends quickly. One retailer lists it as ideal for medium to long hair (Littlewoods, 2026).
Maybe skip: very short hair, very fine and fragile hair that should avoid regular heat, and buyers outside the US who cannot get a local-voltage model.
How to Use It
- Towel dry hair to remove extra water (Ulta, 2026).
- Apply a heat protectant.
- Separate hair into manageable sections (Ulta, 2026).
- Brush through each section slowly from root to end.
- Finish each section on the cool setting to set the style.
Tips for Less Heat Damage
- Start on the lowest setting and only raise it if needed.
- Do not use it on soaking wet hair; towel dry or air dry first.
- Keep the brush moving rather than holding it in one spot.
- Use it a few times a week rather than daily if your hair is damaged.
- Clean hair from the bristles regularly so air flows freely.
Care and Durability
Some buyers report that bristle tips can break after long use (Ulta customer reviews, 2026). Remove hair from the brush after each use, unplug it to cool before storing, and do not wrap the cord tightly around the handle. The swivel cord helps reduce tangles (Life Pharmacy, 2026).
Pros and Cons
Pros
- Dries and styles in one step
- Strong root volume and smooth ends
- Ionic technology for less frizz
- Lower price than many premium hot air brushes
Cons
- US model is 120V only
- Large brush is awkward on short hair
- Regular heat can damage fragile hair
Our Verdict
The Revlon One-Step Volumizer makes salon-style blowouts easy at home, with volume at the roots and smooth, curved ends. Use a heat protectant and lower settings to protect your hair. Buyers outside the US must choose a model made for their local voltage, as the US version is 120V only.
Choosing Accessories That Help
- Heat protectant spray: apply before drying to reduce damage.
- Sectioning clips: make it easier to work in small, even sections.
- Wide-tooth comb: detangle wet hair gently before using the brush.
Working in small sections gives smoother, longer-lasting results than trying to dry large chunks of hair at once.
Making the Style Last
Finish each section with a blast of cool air to set the shape. Avoid touching your hair too much after styling, and sleep with it loosely tied on a smooth pillowcase. On the second day, brush the ends with the brush on the cool setting to refresh the bend without extra heat.
