The REVLON One-Step Volumizer Hair Dryer and Styler is Amazon's best-selling hot-air brush — a 4.6-star average across more than 350,000 ratings and an Editors' Choice pick from Reviewed.com. Reviewers who've run it side-by-side against a separate blow dryer and round brush generally land in the same place: it genuinely cuts styling time in half, but it isn't the gentle, low-heat miracle its viral reputation sometimes implies.
What reviewers consistently praised
Speed is the single most-repeated praise point. Reviewed.com's Rachel Jacoby Zoldan, testing it herself, wrote that on her first try she "couldn't believe how quickly the Revlon Volumizer dried my hair: literally six minutes," crediting the wide, oval barrel and ionic technology for distributing air quickly and evenly. In a separate hands-on test for the same outlet, Jessica Kasparian confirmed the tool's own marketing claims held up under scrutiny: she went "right from wet, limp hair to dry, straight strands" without needing a flat iron afterward, saving roughly 15 minutes she'd normally spend on a straightener. NBC News' Shop TODAY guide adds the styling-expert context for why it works — celebrity stylist Stefan Bertin noted the ceramic coating "evenly distributes heat and leaves hair shiny," while stylist Kevin Murphy pointed to the ionic technology's role in cutting frizz and adding bounce. The tool also went genuinely viral: Shop TODAY reported the #revlonhairdryerbrush TikTok tag had racked up 117.2 million views, with hairstylist Brad Mondo calling it "legit" after trying it himself.
What reviewers consistently pushed back on
The most detailed pushback comes from Reviewed.com's own lab test. Concerned that the metal barrel might run dangerously hot against hair, Kasparian's team placed a heat sensor in the bristles and ran the tool for 30 minutes, recording a maximum of 165–175°F — compared with 153°F for Reviewed's "Best Overall" hair dryer pick, the Bio Ionic. The barrel itself reached 160–165°F, still well below a flat iron's 300–400°F range, but the takeaway was clear: this is "in the same ballpark as a typical hair dryer," not a cool-running alternative. Independent long-term reviewer Hailey at Feeling Good as Hail echoed the heat concern from personal use, and separately flagged that the tool is "moderately loud" — enough that she suggests people with thin walls or noise sensitivity reconsider — and that it carries a plastic smell for the first couple of uses that fades with time. Reviewed.com also dinged the barebones control scheme: only Low, High, and a Cool shot, with no specific temperature readout, which Zoldan called a real drawback for readers with fine hair who prefer to stay in a precise 300–325°F range.
What reviewers liked
- Cuts drying and styling time dramatically — testers clocked full dry-and-style sessions in 6–10 minutes
- Ceramic coating and ionic technology tame frizz without a separate flat iron
- Oval barrel lifts roots for volume while smoothing the rest in one pass
- Praised by working stylists, not just marketing — Bertin, Murphy, and Brad Mondo all endorsed the mechanics
- Far cheaper than premium hot-air stylers like the Dyson Airwrap
What reviewers flagged
- Runs about as hot as a standard hair dryer — lab-tested at 165–175°F on the bristles over 30 minutes
- Only Low/High/Cool settings, no exact temperature control
- Noticeably loud on High; some owners recommend earplugs for repeated use
- Feels bulky and genuinely needs two hands to control well
- New units carry a plastic smell for the first couple of uses
How it compares to alternatives
Reviewed.com directly compared the Volumizer to Revlon's own paddle-brush version, the One-Step Hair Dryer and Styler, and preferred the round-barrel Volumizer for achieving volume more easily. Against pricier hot-air stylers, NBC's Shop TODAY guide frames the value case plainly: the Revlon typically runs under $60, versus roughly $100 for the amika Hair Blow Dryer Brush and about $550 for the Dyson Airwrap — with the Revlon offering six color options where most competitors ship in a single colorway. The tradeoff reviewers describe is precision and cooler operating temperatures on the premium end versus speed and price on the Revlon's end.
Before you buy: what to check
Every source agrees the tool performs best on damp, not soaking-wet or bone-dry, hair — Shop TODAY's usage guide recommends towel-drying and applying a heat protectant before you start, then working in clipped sections. Because there's no exact temperature dial, reviewers with fine or previously damaged hair (Zoldan among them) suggest defaulting to the Low setting and reserving High for thicker, coarser hair. If you're sensitive to noise or already deal with headaches or migraines, factor in the loud, high-pitched motor that multiple independent reviewers describe — the sound itself, more than the heat, is the complaint that shows up most often outside the two Reviewed.com features.
Quick answers to common questions
Does it damage hair? Reviewers are consistent that any heat styling tool carries some risk, and the Revlon's lab-tested temperatures land close to a standard blow dryer rather than a flat iron. Using a heat protectant spray and sticking to the Low setting on fine or color-treated hair is the advice repeated across sources.
Can I use it on fully dry hair? It's designed for damp hair. Reviewed.com's testers and independent owner reviews both prep with towel-dried, detangled hair rather than starting from soaking wet or completely air-dried strands.
Is it worth the price?
Amazon prices shift regularly, so check the live price on the button below rather than relying on a fixed number here. Reviewed.com named it an Editors' Choice pick and Jessica Kasparian's verdict was unambiguous — "Yes, yes, yes" — while still flagging the heat and lack of precise settings as real tradeoffs, not dealbreakers. The consensus across sources is that it earns its reputation on speed and results, provided you're comfortable with a tool that runs warm and loud in exchange for cutting a blowout routine down to single digits of minutes.
Our take, based on the roundup
The reviewers we read are unusually aligned: this brush does what it claims, and does it fast, with real stylist and lab-testing backup rather than just marketing copy. The honest caveats — dryer-level heat, no precise temperature dial, a loud motor, and a break-in smell — are consistent enough across independent sources that they're worth taking seriously if noise sensitivity or fine, damage-prone hair are concerns for you. For everyone else, reviewers agree it's an easy way to cut a blowout down to minutes without buying a separate dryer, brush, and flat iron.

Keeping this review current
Revlon periodically updates colors and bundles, and Amazon pricing shifts often, so we revisit this review periodically rather than treating it as a one-time snapshot. If that changes what's written here, we'll update this page rather than leave outdated claims up.
