You’ve seen it. That chunky, neon-pink-tipped oval brush that looks like it belongs in a 1990s salon but somehow took over every bathroom vanity in the world. It’s the Revlon One Step Hair Dryer and Volumizer Hot Air Brush. If you’ve spent more than five minutes on TikTok or Instagram over the last few years, you’ve watched someone transform their damp, frizzy "just out of the shower" mane into a bouncy, Kate Middleton-esque blowout in roughly ten minutes.
It looks like magic. But honestly? It’s just clever engineering meeting a desperate need for convenience.
For decades, we were told that a professional blowout required the dexterity of an octopus—one hand wielding a heavy ionic dryer, the other twisting a round brush, all while trying not to burn your scalp or tangle your hair into a bird’s nest. Most of us just gave up and used a flat iron. But the flat iron killed the volume. The Revlon One Step changed that because it combined the two tools into one awkward, loud, but undeniably effective wand. It’s not perfect. It’s definitely not a Dyson Airwrap. Yet, it remains a best-seller for a reason.
The Design Flaw That Actually Works
The shape is weird. It’s not round; it’s oval. That’s the "secret sauce" people usually miss when they first buy a Revlon One Step Hair Dryer and Volumizer Hot Air Brush. A round brush gives you curl, but an oval brush gives you lift at the root and a smooth finish on the lengths.
If you use the curved edges, you get that flipped-under look. If you use the flat sides, you’re basically ironing the hair with hot air. The bristles are a mix of nylon pins and tufted boars’ hair. The nylon detangles (mostly), while the tufts create the tension needed to smooth the cuticle.
But let’s be real about the build quality. It’s plastic. It’s bulky. It sounds like a jet engine taking off three inches from your ear. If you have small hands, holding the base can feel like a workout. Despite these "budget" vibes, the airflow is surprisingly consistent. It uses ionic technology to reduce frizz, which basically means it emits negative ions to break down water molecules faster. Does it work? Yes. Is it as sophisticated as the tech in a $500 Italian dryer? No. But for under $60, the results are shockingly close.
Heat Management and the "Toasted Hair" Problem
We need to talk about the heat. This is where most people get it wrong and end up with split ends.

The Revlon One Step Hair Dryer and Volumizer Hot Air Brush gets hot. Very hot. In some independent thermal testing, the "High" setting has been clocked at over 200°F (about 93°C). If you’re pressing that directly against damp hair for extended periods, you are basically slow-cooking your protein bonds.
Expert stylists, like those featured in Allure and Good Housekeeping over the years, consistently warn that the biggest mistake is using this tool on soaking wet hair.
Don't do it.
Your hair is at its weakest when it’s saturated with water. If you start tugging at it with a motorized brush while blasting it with 200-degree air, you’re going to see breakage. The pro move is to air-dry or rough-dry with a normal blow dryer until your hair is about 70% to 80% dry. At that point, your hair is "damp-dry," and the hydrogen bonds are ready to be set into a new shape without the extreme risk of heat damage.
Also, use a heat protectant. Not "maybe" use one. Use it every single time. Look for something with silicones like dimethicone or lightweight oils that can handle high temperatures.
Who Is This Actually For?
If you have fine hair, this tool is your best friend. It creates an illusion of density that a flat iron just can’t touch.

If you have thick, curly, or coily hair (Type 3 or 4), the Revlon One Step Hair Dryer and Volumizer Hot Air Brush is a great "pre-styler." It won't give you a bone-straight silk press—you'll still need a flat iron for that—but it will stretch the curls and dry them much faster than a traditional comb attachment on a blow dryer.
However, if your hair is extremely damaged or chemically bleached to within an inch of its life, be careful. The mechanical tension of the bristles combined with the heat can be a lot. In those cases, the "Cool" or "Low" settings are your only safe zones. Honestly, the "Low" setting on the 2.0 version of this brush is much better than the original, which only had a lukewarm Low and a scorching High.
Versions Matter: The 1.0 vs. The Plus 2.0
Revlon eventually listened to the feedback. They released the "Plus" version (often called the 2.0).
- The Head: It’s detachable now. This is huge because the original was a nightmare to pack in a suitcase.
- The Motor: It’s a bit slimmer, making it easier to grip.
- Heat Settings: They added a medium setting. This was the "missing link." Medium is usually enough to style without feeling like you’re singeing your bangs.
- The Size: The brush head is slightly smaller (about 2.4 inches versus the original 4.2-inch monstrosity), which makes it way better for shorter hair or getting closer to the roots.
If you are buying one today, don't bother with the original "Original" unless it's on a massive clearance sale. The 2.0 is superior in every functional way.
Real Talk: The Longevity Issue
Let's address the elephant in the room. These tools don't last forever.
Because the Revlon One Step Hair Dryer and Volumizer Hot Air Brush pulls a lot of power and generates intense heat, the motors can burn out after a year or two of heavy use. You might notice a burning smell (that’s usually hair or dust trapped in the intake filter at the bottom) or a rattling sound.

To make it last, you have to clean the lint filter at the base. It unscrews or pops off. If that filter gets clogged, the motor overworks, overheats, and dies. Also, pull the dead hair out of the bristles after every use. It’s gross, but if you leave it, the old hair traps heat and ruins the bristle integrity.
How to Get the Best Results (The Step-by-Step)
If you want the "just walked out of a $75 blowout" look, don't just brush your hair like you’re using a regular hairbrush.
- Prep: Apply a volumizing mousse or a smoothing cream depending on your goal.
- Sectioning: This is non-negotiable. If you try to do the whole head at once, the inner layers stay damp and frizz up an hour later. Clip your hair into at least four sections.
- The Root Lift: Place the brush under the section, right at the scalp. Hold it there for 3 seconds. Pull upward, not downward. This defies gravity.
- The Roll: As you reach the ends, rotate the brush. If you want a "C-shape" curl, keep spinning it as you pull through.
- The Cool Shot: If your version has a cool setting, hit the section with it for a few seconds before releasing. This "sets" the style.
The Competitive Landscape
Is it better than the Shark FlexStyle or the Dyson Airwrap?
No. Those tools use the Coanda effect—using air to wrap the hair around a barrel—which is much gentler and more versatile. They also cost between $300 and $600.
The Revlon is a "hot air brush." It uses friction and direct heat. It’s a different beast. But for the average person who just wants to look decent for a 9:00 AM Zoom call or a Friday night dinner without spending forty minutes in front of the mirror, the price-to-performance ratio of the Revlon is unbeatable. It’s the "Honda Civic" of hair tools: reliable, affordable, and gets the job done, even if it’s not flashy.
Moving Forward With Your Hair Routine
To keep your hair healthy while using a hot air brush, consider a "hair diet." Don't use it every single day. Give your hair a break with air-drying or heatless styles a few times a week.
If you decide to pick up the Revlon One Step Hair Dryer and Volumizer Hot Air Brush, start with the "Low" or "Medium" setting first. You might be surprised at how little heat you actually need once the hair is mostly dry.
Actionable Next Steps:
- Check your current hair moisture levels; never use this tool on dripping wet hair.
- Clean the bottom air intake filter on your device every two weeks to prevent motor burnout.
- Invest in a high-quality microfiber hair towel to speed up the pre-styling drying process without causing frizz.
- Rotate your wrist while styling to ensure the oval edges are doing the heavy lifting for volume.
