The Revlon One-Step and the Shark FlexStyle promise the same thing: salon hair at home, no skill required. One costs as much as a nice dinner. The other starts at $250 and goes up to $379. Both lineups got bigger in 2026. Revlon fixed the original’s biggest problems with the PLUS update. Shark added the IonCurl for curls and the Glam for ceramic styling.
Quick take: You just want a big bouncy blowout? Buy the Revlon One-Step PLUS for $42 and you’re done. Side by side, its blowout looks as good as the Shark’s at one-fifth the price. You want one tool that dries, curls, smooths, and diffuses? That’s when the FlexStyle makes sense. That versatility is what your extra $200+ buys you. All six tools were live on Amazon when we checked.

We looked at the full 2026 lineups from both brands. Three Revlon brushes: the PLUS, the Original, and the Root Booster. Three Sharks: the standard FlexStyle, the new IonCurl, and the Glam. All live Amazon listings. Prices from $42 to $379. We checked styling range, heat control, how barrels and attachments fit different hair lengths, weight, ergonomics, and what each price jump actually gets you.
The Real Question: Blowout Tool or Multi-Styler?
These products solve different problems. The Revlon is a blowout brush. Hot air plus a big bristled barrel dries and volumizes your hair in one pass. The FlexStyle is a multi-styler. It’s a dryer wand that takes curling barrels, smoothing brushes, concentrators, and diffusers. You only ever dry your hair with volume? The extra $200 buys you attachments you’ll never use. You switch between blowouts, curls, and waves? One FlexStyle replaces three tools.
Detailed Reviews
1. Shark FlexStyle Multi-Styler (HD440BK) - Best Overall
Shark FlexStyle Air Multi-Styler (HD440BK)
The standard FlexStyle is still the best value in Shark’s range at $250. You get a powerful dryer whose head rotates from wand to compact dryer. The coanda curlers wrap your hair using airflow instead of extreme heat. Plus you get an oval brush, paddle brush, and concentrator. Blowouts look great. Curls work even if you’re not an expert. The no-extreme-heat approach is easier on fragile ends. Two complaints carry into 2026. You have to swap barrels to change curl direction. That’s tedious. And at five times the Revlon’s price, you need to actually use that versatility.
2. Revlon One-Step Volumizer PLUS - Budget Pick
Revlon One-Step Volumizer PLUS (2.4" Barrel)
The famous pink-and-black brush grew up. The PLUS update brings a slimmer 2.4” oval barrel that gets closer to your roots. Detachable head for travel. A fourth heat setting in the medium range. Charcoal-infused pins. A longer-lasting motor. Revlon fixed the original’s weak spots. The blowout itself is the same magic trick. Damp hair to smooth bouncy finish in one pass for $42. It still runs hot. Use the medium setting and keep it moving. And it does exactly one thing. But that one thing is what most people bought a FlexStyle for.
3. Revlon One-Step Original 2.8” - Best for Maximum Volume
Revlon One-Step Volumizer Original (2.8" Barrel)
This is the tool that started the blowout-brush wave. Still around $47 and still the volume king. The oversized 2.8” barrel grabs big sections and gives you max root lift and bouncy rounded ends. On medium-to-long hair it out-volumizes everything here. Including the Shark. The trade-offs are what the PLUS fixed. Bulky fixed head that fights short styles. Three heat settings. No travel-friendly disassembly. Your hair’s past your shoulders and you want volume? The original is still the pick.
4. Revlon One-Step Root Booster - Best for Short or Fine Hair
Revlon One-Step Root Booster (1.5" Barrel)
Short hair, bobs, bangs, and flat fine roots are where big oval barrels fail. That’s where this 1.5” round brush earns its $50 price tag. It delivers real lift at your crown. Bends layers under or out. Shapes fringe without creasing. It’s slow on long thick hair. Wrong tool for that job. But for short-and-fine hair it beats both the big Revlons and the Shark’s brush heads at root work.
5. Shark FlexStyle IonCurl - Best for Curls
Shark FlexStyle IonCurl (HD840PU)
Shark dropped this in July 2026 to fix the FlexStyle’s known weakness: curls that fall out by lunch. IonCurl pairs CoandaBoost airflow with Ion Smooth Technology. The result is bouncier more defined curls that hold past lunchtime with way less frizz than the standard model. At $299 it’s the one to buy if curls are your default style. Not blowouts. It’s also brand new. Its long-term durability record is still being written. Early signs look strong.
6. Shark FlexStyle Glam - Worth the Upgrade
Shark FlexStyle Glam (HD6051SPK)
The Glam tops the range at $379. It adds the one thing air-only stylers can’t do: ceramic contact styling. It combines heated ceramic surfaces with FlexStyle airflow. Works on both wet and dry hair. So day-two touch-ups don’t need a full rewash-and-restyle. It produces the most polished salon-finished results of anything in this comparison. It’s more tool than a casual user needs. But you style your hair daily and you want dryer, curler, and finisher in one premium device? It’s the upgrade that earns its price.
Which Should You Buy?
- You want volume, full stop: Revlon One-Step PLUS (~$42) — or the Original 2.8” if your hair is long.
- Short hair or flat roots: Revlon Root Booster.
- You style multiple ways weekly: Shark FlexStyle HD440BK (~$250).
- Curls are your signature: Shark IonCurl ($299).
- You want the whole salon in one handle: Shark Glam (~$379).
FAQ
Is the Shark FlexStyle really better than the Revlon One-Step? For blowouts alone? Barely. Side-by-side results are surprisingly close. The FlexStyle wins on versatility. Curls, diffusing, smoothing, and a genuinely good standalone dryer.
Which Revlon One-Step should I buy in 2026? The PLUS (2.4”) for most people. Detachable head, better heat control, easier handling. The Original 2.8” for maximum volume on longer hair. The Root Booster for short or fine hair.
Is the new Shark IonCurl worth $299 over the regular FlexStyle? If curl definition and hold are your priority? Yes. The ion technology and CoandaBoost measurably improve both. You mostly do blowouts? The standard model does the job for less.
Do these tools damage hair? All hot tools stress your hair. These are gentler than flat irons because they style at lower temperatures with moving air. Use the lowest heat that works. Keep tools moving. Use a heat protectant spray.
Can the Shark FlexStyle replace my hair dryer? Yes. The wand rotates into a compact dryer with strong airflow. That’s a real part of its value story versus buying a separate dryer and styler.
The Bottom Line
The honest math hasn’t changed. The Revlon One-Step PLUS delivers 80% of the blowout for about 17% of the price. That makes it the default answer for most people. The Shark FlexStyle wins when versatility is the point. And in 2026 the line finally offers real choices. The $250 standard model for all-rounders. The IonCurl for curl devotees. The Glam for those who want ceramic polish and wet-or-dry flexibility in one premium tool. Buy for the styles you actually wear. Not the ones the attachment box promises.
