A thermal brush is how you get a salon-style blowout at home without wrestling a round brush and a dryer in separate hands. It heats its own barrel and shapes and smooths in far fewer passes, so a bouncy finish stops feeling like a two-person job once your hair is already dry. But barrel size and heat technology vary more than shoppers expect, and picking the wrong size for your length is the most common mistake. We analyzed thousands of verified buyer reviews, recent sales data, and expert evaluations to find six thermal brushes that shape cleanly and hold up over time.
Our Best Overall pick: Wavytalk's streamlined thermal brush with a 1.5 inch ionic round barrel, three straightforward heat settings up to 410F, and dual voltage for travel, combining strong buyer feedback with a reasonable price.
Our Best Affordable pick: the five-setting Wavytalk, independently tested by CNN Underscored, with a 1.5 inch tourmaline ceramic barrel, heat up to 420F and negative ion technology for a gentler, bouncy blowout at a discounted price.
The size-up Wavytalk sibling, carrying the same 5-setting tourmaline ceramic and negative-ion formula as the Blowout Boost into an oversized 1.77" barrel built for long or thick hair.
L'ANGE Le Volume 2-in-1 Titanium Blow Dryer Brush (60mm)
4.7
60mm oval barrel · 1100W airflow · 10 speeds
Our Best for Everyday Blowouts pick: a titanium ionic barrel with a built-in dryer fan that dries and styles damp hair in one step instead of needing hair dry first.
The mass-market original 2-in-1: a large 2.8 inch oval brush with a built-in dryer that dries and volumizes damp hair in one step, with ceramic ionic technology, 3 heat settings and a 4-year warranty.
Short on time? These three cover most buyers: our top-graded pick is Wavytalk's streamlined Blowout Express, our most affordable pick is the five-setting Wavytalk Blowout Boost, and our everyday-blowout pick is the L'ANGE Le Volume, a 2-in-1 that dries and styles damp hair in one step.
Understand the category before you buy - what the science actually says, and which specs matter.
Every thermal brush promises a smoother, fuller look, but barrel size and the heat technology inside it change what a given brush can actually do for your hair. Here is how they work and the features worth comparing before you buy.
What does a thermal brush actually do?
A thermal brush combines the bristles of a round brush with a heated or heat-holding barrel, so the tool that shapes your hair is also the tool that sets it. As you roll a section around the barrel, heat relaxes the hair and the bristles guide it into a curve, and when the section cools it holds that shape. Depending on the model, the same tool can build volume at the roots, bend the ends under, or smooth frizz on a straight finish.
It wraps hair around a barrel like a round brush.
Heat sets the shape as the hair cools on the barrel.
Ceramic, tourmaline, ionic, and infrared features aim to spread heat evenly and cut frizz.
Barrel size and heat technology are what separate these brushes
Every round brush in this comparison heats its own barrel rather than blowing warm air through it, so most are meant for hair that is already dry or nearly dry - plan on a normal blow-dry first, then use one of these to shape and set the finish. The ELLA BELLA even specifies dry hair only; the L'ANGE Le Volume is the exception, with a built-in dryer fan that dries and styles damp hair in one step, and the L'ANGE Le Vite is a flat straightening brush rather than a round barrel.
What changes from model to model is barrel diameter. A larger barrel builds volume and soft, sweeping bends, while a smaller one grips shorter hair and adds tighter curl. This lineup runs from matching 1.5 inch round barrels on the Wavytalk Blowout Boost and Express, up to the 1.77 inch Wavytalk Grande and the 1.8 inch ELLA BELLA for the biggest, loosest curls. The L'ANGE Le Volume takes a different shape entirely with a 60mm oval barrel built around a dryer fan, and the L'ANGE Le Vite skips a barrel altogether in favor of flat ceramic plates for straight, smooth results.
Heat technology is the other differentiator. Ceramic and tourmaline aim to heat evenly, ionic and negative-ion features target frizz, and infrared, found on the ELLA BELLA, warms hair more gently from within. Match the barrel to your length and the technology to how gentle you need the heat to be.
Which specs actually matter?
A few features decide the fit:
Barrel diameter and shape: Bigger barrels (the 1.8 inch ELLA BELLA and the 1.77 inch Wavytalk Grande) favor volume and loose bends; smaller ones (the 1.5 inch Wavytalk Blowout Boost and Express) grip short hair and add curl. The oval 60mm Le Volume blow-dry brush takes a different shape entirely, drying and shaping hair in one step rather than requiring hair to already be dry, and the L'ANGE Le Vite swaps the barrel for flat ceramic plates.
Technology: Ceramic and tourmaline aim to heat evenly, ionic and negative-ion features target frizz, and infrared, found on the ELLA BELLA, warms hair more gently from within.
Heat settings: Range and control matter for matching your hair. This lineup spans from 3 settings on the Wavytalk Express and the L'ANGE Le Volume up to 5 on the Wavytalk Blowout Boost and Grande, with maximum temperatures from 392F to 450F, so finer or color-treated hair can stay on the lower end.
Dual voltage: Most brushes in this lineup are dual voltage, which means they work abroad without a converter if you travel - the Le Volume 2-in-1 dryer brush is the exception, built for 125V household current only.
Safety features: Look for auto shut-off and a swivel cord, both of which the ELLA BELLA includes, so a forgotten hot tool powers down on its own.
Weight: These range from under a pound up to 2.12 lb, and a lighter tool is easier on your arm through a full styling session.
How we grade products
Graded Picks rankings are aggregated from several independent signals: verified buyer ratings and the size of the review base for credibility, recent monthly purchase volume for relevance, assessments from trusted hair and styling publications, and how each product places in leading category lineups. For thermal brushes we weigh:
Heat source type and how it fits real routines
Barrel size and shape versatility
Evenness of heat and frizz control technology
Range and precision of heat settings
Ease of handling and weight
Safety features like auto shut-off
Overall value for the price
Heat safety note: These tools reach up to 420F, hot enough to damage hair and burn skin. Start on the lowest setting that gets results, keep the barrel moving rather than resting it against your scalp, and use a heat protectant. Unplug a heated brush after every use, and lean toward models with auto shut-off if you tend to rush out the door.
In-Depth Reviews
Everything we learned from buyer reviews and expert testing, product by product.
Our Best Overall pick. The Blowout Express is Wavytalk's updated, simplified take on the round thermal brush: a 1.5 inch ionic barrel built to smooth and add shine on dry hair, with three fixed heat settings at 330F, 370F, and 410F that keep the controls simple rather than fiddly. It runs on negative ion technology to cut frizz, weighs about 14 ounces, and is dual voltage so it travels internationally. It shares the same 1.5 inch barrel size as the flagship Blowout Boost below while paring the heat range down to three settings, and it combines that simplicity with consistent heat performance and a reasonable price to edge out its siblings as the top-graded pick in this comparison. It carries Wavytalk's standard 1 year warranty.
The Blowout Boost is our Best Affordable pick: it carries the widest heat range among the 1.5 inch brushes here at roughly $47 with an active discount, and it is the one CNN Underscored put through independent testing, coming away calling it worth the hype for the price. Its 1.5 inch tourmaline ceramic barrel heats in about 30 seconds and offers 5 temperature settings from 300 to 420F, with negative ion technology working alongside the ceramic coating to cut frizz, add shine, and keep heat stress lower than plain-ceramic brushes. It is dual voltage for travel and, per that same testing, performs best on wavy or curly hair after soft, bouncy volume rather than pin-straight hair chasing maximum curl tension. Its Express sibling keeps the same 1.5 inch barrel size with a simpler three-setting heat range and edges it out as our Best Overall pick, while other products in this lineup, like the ELLA BELLA, take a different barrel size and technology entirely.
Barrel/plate shape & sizeRound barrel, 1.5"
Max temperature420°F
Heat settings5 settings (300-420°F)
TechnologyTourmaline ceramic, negative ion
Power source & voltageCorded, dual voltage
Weight13.44 oz
Warranty1-year manufacturer warranty
Pros
Independently tested by CNN Underscored with a positive verdict, at a discounted price
5 heat settings cover a wide range of hair types
Tourmaline ceramic and negative ion technology for shine and frizz control
Dual voltage and fast sub-minute heat-up for travel
Lightweight and easy to maneuver for a heated barrel brush
Cons
Testing found it best suited to wavy or curly hair rather than max curl tension on straight hair
Corded design limits reach compared with cordless styling tools
The single 1.5" barrel means longer or thicker hair may do better with a larger-barreled option elsewhere in this comparison
Who is it for?
Budget-minded buyers who want five heat settings and a tested Wavytalk brush for bouncy blowouts across most hair types and lengths.
Who is it not for?
Anyone with very long or thick hair who'd benefit from a larger barrel (see the ELLA BELLA below), or naturally straight hair chasing maximum curl tension.
ELLA BELLA's entry has the largest barrel in this comparison at 1.8", positioned as a volumizer-and-curler-in-one for dry hair, with infrared heat meant to warm hair from within and negative ion technology plus aloe-enriched bristles for a gentler glide through the hair. Its dial adjusts across a 140-200°C (roughly 284-392°F) range, and it includes an auto shut-off and swivel cord alongside dual voltage for travel. It's the newest and least-established brand in this lineup, with far less independent testing behind it than the Wavytalk or L'ANGE products, so the case for it rests mainly on the large barrel size and feature list rather than a proven track record.

Auto shut-off and swivel cord for everyday convenience
Cons
The newest, least-established brand in this comparison
Far less independent testing available to confirm performance claims
Noticeably heavier than the compact 1.5" brushes in this lineup
Who is it for?
Buyers chasing big, voluminous curls from the largest-barrel round brush in this comparison.
Who is it not for?
Anyone who wants an established, heavily-tested brand track record or a lighter, more compact tool.
4. Wavytalk Blowout Boost Grande 1.77" Thermal Brush
4.7
The Grande carries the Blowout Boost's core recipe (tourmaline ceramic, negative ion technology, the same 300-420°F range across 5 settings, all aimed at cutting frizz and heat stress) into a scaled-up 1.77" barrel specifically for long or thick hair that would otherwise need many more sections with the compact 1.5" siblings. Dual PTC heaters keep heat distribution even across the larger surface, which matters more as barrel size increases. It's the size-based option in this Wavytalk trio: the standard Boost is the balanced all-rounder, the Express is the simplest, top-graded option, and the Grande is for buyers who specifically want fewer passes on longer or thicker hair with the same gentle formula.
Barrel/plate shape & sizeRound barrel, 1.77"
Max temperature420°F
Heat settings5 settings (300-420°F)
TechnologyTourmaline ceramic, negative ion
Power source & voltageCorded, dual voltage
Weight0.5 lb
Warranty1-year manufacturer warranty
Pros
Oversized 1.77" barrel covers more hair per pass than the standard Boost
Same 5-setting, 300-420°F range as the Blowout Boost
Dual PTC heaters for even heat across the larger barrel
Tourmaline ceramic and negative ion technology for shine and frizz control
Dual voltage for travel
Cons
Bulkier and heavier to maneuver than the compact 1.5" siblings
Overkill for short or fine hair that doesn't need the extra barrel size
Shares the same brand-wide durability questions common to budget thermal tools
Who is it for?
Buyers with long or thick hair who want to cover more hair per stroke and cut overall styling time.
Who is it not for?
Short-hair or fine-hair users who'll get better control from the compact 1.5" Boost or Express.
5. L'ANGE Le Volume 2-in-1 Titanium Blow Dryer Brush (60mm)
4.7
Our Best for Everyday Blowouts pick. The L'ANGE Le Volume is built to work on damp hair, a job it shares only with the Revlon One-Step below: its oval 60mm titanium, ionic barrel pairs with a built-in dryer fan across 10 airflow speeds and 3 heat settings, so it dries and shapes hair in one pass rather than requiring a separate blow-dry first. Reviewers consistently praise the smooth, shiny, frizz-reduced results and note the snag-resistant bristles grip hair firmly enough to build real volume at the roots. The tradeoffs are size and power: at 1.32 pounds it is bulkier than the barrel-only brushes here, and its 1100 watt motor is more modest than a dedicated dryer, so very curly hair or humid climates can need extra passes. Against the Revlon it trades a smaller barrel for titanium and finer airflow control. As with its L'ANGE siblings, weigh the brand's recurring minority of reports about heating elements not lasting as long as expected. It carries a 1 year manufacturer warranty.
Barrel/plate shape & sizeOval barrel, 60mm
Max temperature200°C (392°F)
Heat settings3 heat settings, 10 airflow speeds
TechnologyTitanium barrel, ionic technology, built-in dryer fan
Power source & voltageCorded, 1100W, 125V
Weight1.32 lb (600g)
Warranty1-year manufacturer warranty
Pros
Titanium ionic barrel dries and styles in a single pass
10 airflow speeds plus 3 heat settings for fine control
Snag-resistant bristles grip hair for volume and tension while smoothing frizz
Includes a protective storage cover and cleaning brush
Cons
Bulkier oval barrel than the pure thermal brushes in this lineup - some buyers find it less nimble on short hair
1100W airflow can struggle to fully tame very curly or humid-climate hair in a single pass
Shares the brand-wide pattern of scattered reports of heating elements failing sooner than expected
Who is it for?
Buyers who want to dry and style in one step rather than blow-drying first and then using a separate heated barrel.
Who is it not for?
Anyone who wants a lighter, more compact tool or prefers styling only fully dry hair with a dedicated thermal barrel.
The Revlon One-Step is the familiar drugstore-shelf version of the dryer-brush idea: a 2.8 inch oval paddle brush with a built-in 1100 watt dryer, ceramic coating and an ionic generator, so damp hair is dried and given lift at the roots in one pass. Reviewers at Reviewed, TechRadar and Marie Claire praise how quickly and easily it dries hair compared with juggling a round brush and a dryer, how well the mixed nylon and boar bristles grip fine hair, and how affordable it is, with a swivel cord and 3 heat settings for flexibility. The oval shape can be slid under the hair to lift the roots and add swing, and Revlon backs it with a 4-year limited warranty. The tradeoffs are bulk: the wide handle can tire the thumb, it is heavy for the category and not well balanced, and the large barrel is awkward on short hair. Compared with the L'ANGE Le Volume above, it offers a bigger barrel and a longer warranty but no titanium barrel or multi-speed airflow control, and unlike the barrel-only thermal brushes it is a drying tool rather than a dry-hair finisher.
Barrel/plate shape & sizeOval barrel, 2.8"
Max temperatureAbout 165 to 175°F (measured air temperature)
Heat settings3 heat settings
TechnologyCeramic coating, ionic technology, built-in dryer fan
Power source & voltageCorded, 1100W, 120V
WeightAbout 1 lb (16 oz)
Warranty4-year limited warranty
Pros
Dries and volumizes damp hair in one step, faster than a round brush and dryer
Large 2.8 inch oval barrel lifts roots and adds swing on mid-length to long hair
Ceramic and ionic technology for a smoother, shinier finish
Swivel cord and 3 heat settings for flexibility
4-year limited warranty is the longest in this comparison
Cons
The wide, heavy handle can make thumbs ache and feels poorly balanced
Not easy to use on short hair, and the bristles can bend if not stored upright
Fewer controls than the L'ANGE Le Volume, with no titanium barrel or multi-speed airflow
Who is it for?
Buyers with mid-length to long hair who want a simple, affordable one-step dryer brush for damp hair.
Who is it not for?
Short-haired buyers, anyone sensitive to a heavy handle, or those who style fully dry hair and want a slim heated barrel.
