Top 7 Best Hair Brush Straightener Reviews for Apr. 2021 – With Buying Guide
The Groom+Style review team untangle the mysteries of straight hair, and line up a list of the best hair straightening brushes for you!
Why do we always want what we can’t have?
Many women with straight hair fantasize about having lavish curls. Similarly, women with curly or wavy hair would give almost anything to have sleek, shiny, straight hair.
Curling straight hair is relatively easy; perms and curling irons have been around for several years. Those with wavy hair that doesn’t relax even after blow drying, endure more tortuous methods to change the look of their locks. Hair relaxer (straightener) products and hair dryers released over the years have often been hit or miss with many users.
Only recently have hair brush straighteners, like hot combs and modern flat irons, become more reliable and safer to use on a regular basis.
Please find our detailed analysis, buying guide and test results of all the best hair brush straighteners after the summary table.

Buying Guide – Types of Hair Brush Straighteners
There are many women for whom a flat iron simply isn’t the right choice; their sensitive or thin hair is quickly turned to toast by the high temperatures produced by flat irons.
That’s why electric hair brush straighteners became an overnight sensation a few years ago when videos of these often odd-looking contraptions started popping up on YouTube and Facebook. Manufacturers quickly responded, and today there is a wide variety of brush straighteners to choose from.
There are two common types of hair brush straighteners. “Paddle” or flat brushes look and perform very much like standard detangling brushes, with bristles built into a ceramic or tourmaline plate. The heat generated by the plate works to straighten the hair while releasing negative ions that make it shiny and smooth.
“Barrel” or rotating hair brush straighteners also detangle, straighten and add shine. In addition, hot air is directed into the hair as their ceramic or metallic barrels rotate, adding volume to thin hair. These are the best option for long hair, and the fact that the barrels are circular provides the added benefit of being able to curl as well as straighten.
Less common but still worth mentioning are “hybrid” styles of hair brush straighteners. Some are similar to a flat iron but with bristles on each of the plates, while others have a rotating barrel on one side and a plate with bristles on the other. You’ll also see lots of inexpensive, non-heated straightener brushes, but we won’t be focusing on those in our reviews.
For more details about what is right for your hair read Groom+Style’s hair straightener buying and user guide – flat iron or brush, what is best for your hair.
Important Features of Hair Brush Straighteners
Heat levels are most important, and everything else is tied for second place. The true benefit of these appliances is that lower temperatures are suitable for easily-damaged or thin-to-medium hair, so it’s crucial that they’re able to operate at the appropriate temperatures. 365° is considered optimal for medium-thick hair, and straightening very thin or brittle hair calls for temperatures closer to 300°. Some models also have settings as high as 450° for use on very thick or very curly hair.
Before choosing a hair brush straightener, be sure that the heat options match your type of hair and also check how long the model takes to reach temperature.
Type of Straightening Plates Used
Hair brush straighteners will have either ceramic, or ceramic and tourmaline, or titanium plates.
Ceramic is the most common for home hair brush straighteners and is generally the best choice for delicate, fine or color-treated hair because it heats evenly and a bit slower than tourmaline or titanium, and does not generate hot spots.
Tourmaline and titanium, by contrast, heat up extremely quickly and can damage thin or sensitive hair before you’re even aware that it’s happened. You will commonly find tourmaline and titanium straighteners used in professional salons as the stylists have the necessary training to correctly use these products.
Tourmaline has the advantage of producing 20x more negative ions than ceramic straighteners, which is great for making coarse hair shine, and reducing frizz and static.
Titanium heats up even faster (and more evenly) than tourmaline, but due to the fact that it can hold intense heat, it is not recommended for anything other than styling really thick hair, or for those with experience handing these devices.
You will find tourmaline and titanium more commonly used in flat iron hair straighteners rather than hair brush straighteners (although there are some options provided below), due to the fact that flat irons as specifically designed to straighten hair, while hair brush straighteners are used not only to straighten but to style and sometimes to create volume.
Types of Bristles
The bristles on a hair brush straightener should also be considered.
Nylon is best for sensitive scalps or hair that doesn’t become a bird’s nest in the blink of an eye. Some straighteners have bristles tipped with tiny balls made of silicone, rubber or other materials, and they’re a better choice for women whose hair tangles easily because they help “cut through” the tangles without snagging. They’re more comfortable, too.
Other factors may also be important to you, including the weight of the unit, how comfortable the handle feels in your hand, whether there is an LCD display and an automatic shut-off feature, and the length of the power cord. But remember: heat levels come first, because they determine whether your hair comes out straight, shiny and silky – or a damaged, fried mess. Everything else is secondary.
Below is Groom+Style’s list of the best hair brush straighteners on the market. Alternatively, follow this link to find out about the top 5 best flat iron hair straighteners.
1. Glamfields Heated MCH Hair Straightening Brush
When is a “big head” a positive instead of a negative? When the head is on a high-quality hair brush straightener, of course. This Glamfields product jumped to the top of our rankings because the Groom+Style review team simply loved the large size and shape of its rectangular brush head; it’s bigger and wider than on other straightening brushes, allowing it to grab more hair on each pass. That, plus the comb’s dense teeth, lets you get the job done more quickly, whether your hair is thick or thin, lustrous or dry.
The Glamfields straightener, like most of our top-ranked models, releases negative ions to fight frizz while preventing split ends and knotting. Performance, though, sets it apart from the pack. Hair is straightened beautifully and quickly with the unit’s metal ceramic heater requiring just a 40-second warm-up, eliminating a long wait for the brush to reach temperature. And speaking of temperature, there are 12 heat settings ranging from 250° (ideal for brittle hair) to 450° (hot enough to straighten extremely thick or wavy hair).
This hair brush straightener is well-designed and comfortable to hold, with a 360° swivel power cord that lets you position the brush at any angle you find optimal. It comes packaged with a heat-resistant glove, in a gorgeous gift box. And somewhat surprisingly for a high-end product, it’s priced very reasonably. The team had no trouble ranking the Glamfields brush at number one.
There’s almost nothing negative to say about the Glamfields hair brush straightener, which does a terrific job on every type of hair – and does it quickly, for a great price.
Checking the specifications of the Glamfields Heated Hair Straightening Brush:
No products found.
Here’s a slight caveat to our effusive praise of the Glamfields model as “the best” hair straightener brush: this AsaVea is slightly better for thicker hair. However, it’s usually more expensive and not as good for thin hair.
Once again, the key to this brush’s performance is a big comb which grabs large volumes of hair, with a curved base that funnels hair right to the comb. It also delivers heat via metal ceramic (MCH) technology; the combination guarantees very fast hair straightening, as it does with Groom+Style’s #1 straightening brush. Heat-up time for the AsaVea is about 60 seconds, slightly longer than it is with the Glamfields but not bad at all.
There are 12 heat settings on this brush with a selectable temperature range from 250-450°, so it can be used on all types of hair even though it’s best on thick locks. However, this model does not generate negative ions, which are the best weapon against frizz and create smoother, shinier hair. (The AsaVea 4 does use ionic technology and sells for a similar price, but the review team prefers the 3.0 because it uses MCH for more consistent heat delivery, doesn’t have brush tips that can catch on hair, and has more heat settings.)
An additional nice touch is that the AsaVea’s has an anti-scald feature similar to the Glamfields, which ensures that the hot brush won’t touch or burn your skin.
The AsaVea 3.0 is the best straightening brush for those with very thick hair, but it isn’t the best choice for thinner or brittle hair and won’t defrizz hair quite as efficiently as the Glamsfield.

3. MiroPure 2-in-1 Ionic Hair Straightener Brush
Now it wouldn’t be fair to highlight a straightening brush that’s great for thick hair without also selecting a product that’s best for extremely thin or damaged hair. The MiroPure has 16 different heat settings and is capable of reaching 450° to straighten all types of thick and normal hair. What’s most notable, though, is that it can straighten hair at temperatures as low as 170°, perfect for very thin hair that’s likely to be fried at higher temperatures. It’s difficult to find a model suitable for that type of hair; the review team recommends the MiroPure.
The high-density bristles on the professional-style nano comb are designed to prevent curly hair from catching in the teeth. However, that also means straightening your hair can take longer than it does with the Glamsfields or AsaVea, because you may need to make more passes with the brush. Heat-up is fast (60 seconds) and the heat is evenly-distributed thanks to metal ceramic technology. The double-ionic generator works to prevent frizz and split ends.
This model has anti-static control and comes with a heat-resistant glove. You’ve probably guessed by now that the MiroPure, like its major competitors, is only meant for use on dry hair. And it’s usually priced lower than both of the models ranked higher by Groom+Style, making this an excellent alternative to those products.
The MiroPure 2-in-1 is a very good brush straightener for all types of hair, and it’s the best choice for those with damaged or thin hair.

4. Apalus Brush Hair Straightener
The Apalus is another flat heated hair brush, primarily for use on dry hair. It applies constant heat when you turn it on, although it takes longer to warm up than models which use metal ceramic heating technology (this one simply uses ceramic plates). It can reach 180°F in 60 seconds, but will take three minutes to hit its top temperature of 450°. That can make this unit frustrating to use if you have to straighten thick hair.
The brush is automatically programmed to operate at 365° which is suitable for delicate hair, but has optional settings for hair with a natural texture (410°) or is very thick or wavy (450°). The brush has no-scald tips, so there are no concerns about the high temperatures damaging your hair or your hands.
The Apalus works relatively quickly, taking approximately ten seconds per pass to straighten most types of hair, although you will have to straighten small sections at a time. That makes it an inexpensive lifesaver if you need a quick straightening before heading off to work. The Apalus hair straightener can also be used as a detangling brush and massager to straighten frizzy or unmanageable hair, if used in conjunction with Agam essential oil or Moroccan oil.
A great straightener to be used on dry hair which works quickly.
Features of the Apalus Brush Hair Straightener:
The Revlon One-Step Hair Dryer and Volumizer is combines a hair dryer and a brush in one appliance. Its ideal use is for styling longer hair or creating greater volume.
The Revlon One-Step works best on partially dry hair. Hot air blows from inside the brush while the soft bristles brush to take the curl and tangles out of your hair. Alternatively, you can leave the ends of your hair curly while straightening the rest. The added benefit of a unit that has hot air blown from the inside is that you don’t have to wait for the straightener to heat up.
The brush has three heat settings, which includes a cold shot button to cool things down when required.
The Revlon One-Step is very effective, but it does have a very large handle which can make it difficult to maneuver. It comes with an unusual two-year warranty; most competitors only offer one year of buyer protection.
A very good straightening/volumizing tool at a reasonably low price, the Revlon One-Step is a wonderful and versatile hair appliance for those people who want greater volume, and don’t necessarily like to blow dry their hair.
Features of the Revlon One-Step Hair Dryer and Volumizer:
At first glance, the InStyler appears to be similar to a flat iron. However, the side with the flat plate actually has a brush mounted onto it; the other side contains a rotating titanium barrel.
This rotating iron can be used on semi-wet, towel-dried hair. The barrel side goes closest to your head, and as it rotates (in either direction) while being pulled through your hair, it dries it. Meanwhile, the heated brush straightens the hair. There are also ionic bristles to fight frizz.
The end result is straight hair that has more fullness than if you used a flat iron. The InStyler performs best if you run the appliance through each hair section twice.
The brush uses MCH technology, it takes approximately 30 seconds for the brush to reach temperature, and there are four temperature options that range up to 425°. There’s an automatic shut-off safety feature as you’ll find on most straighteners. As an added benefit, the InStyler can also be used to curl hair or flip ends, just by wrapping the hair around the barrel and letting it rotate for approximately five seconds.
This brush is more expensive than the other models in our rankings, so the review team has placed it at #6. However, despite its slightly strange appearance, the InStyler is a powerful hair straightening tool that is more versatile than most options if you want to style as well as straighten.
Features of the InStyler Wet To Dry Rotating Iron:
7. DAFNI The Original Hair Straightening Ceramic Brush
The DAFNI is the top-quality hair straightening brush that set social media on fire when videos featuring the tool started appearing a few years ago. You can only use it at 365° (when all four LEDs light up, you know it’s ready) so it doesn’t get hot enough to work effectively on extremely thick or knotty hair, and it may be a bit too hot for severely damaged or thin hair. But 365° is perfect for medium-to-thin hair, making the DAFNI easy and rewarding to use for most women.
The Groom+Style review team was amazed at how quickly the ceramic-coated plate on this hair straightening brush heats up, taking well under a minute to be ready for use. The bristles themselves are slightly less comfortable than on some competitors since they don’t have supplemental tips.
But the DAFNI is the only straightener with springs underneath the bristles, which ensure they won’t hurt at all as you run them across your scalp. For the majority of users the entire detangling, straightening and de-frizzing (there’s a negative ion function) will take less than five minutes.
The DAFNI, like most hair straighteners, is designed to work only on clean and dry hair and works best if you use a keratin treatment before straightening. By following that recommendation from the company, even naturally-curly hair will stay straight and smooth for as long as several days.
You’ll pay a somewhat higher price for the DAFNI’s brand name, but the tool is worth it – as long as you’re not trying to straighten really thick, problem locks or thin, damaged hair.
Features of the DAFNI The Original Hair Straightening Ceramic Brush:
Bonus Straightener #1 – CNXUA Ionic Hair Straightener Brush
CNXUA is (understandably) not a name as well known as the brands that came in ranked 1-7 by our review team, but it makes a very comparable straightener brush when it comes to features and results. This brush is another ceramic model powered by metal ceramic heater (MCH) chips, known for their high thermal efficiency– in short, it means they transfer heat quickly and uniformly, and do it well.
The bristles are also ceramic but in a nice touch, they’re surrounded by plastic bristles which minimize the danger of accidental burns to the hand or scalp. The CNXUA heats up fully in 60 seconds or less, and makes short work of curly hair that needs straightening. G+S likes the fact that the five heat settings can hit a low of 300°, which is ideal for most thin or easily-breakable hair. On the other end of the spectrum, it can heat to 450°to straighten stubborn thick or African-American hair.
This brush also features negative-ion technology which nourishes hair from within, making it stronger and healthier while reducing frizz. This is a dual-voltage capable hair straightener, with a swiveling power cord, auto-shutoff and an LED display that can toggle between °F and °C.
If you don’t find anything you like in our top 7 then the CNXUA is worth your consideration. It’s just about as good, at a comparable price.
Features of the CNXUA Ionic Hair Straightener Brush:
Bonus Straightener #2 – Larmhoi Ceramic Hair Straightener BrushNo products found.
Even the hair brush straighteners at the top of the Groom+Style rankings aren’t budget busters. If you’re searching for something that’s a little less expensive but can still do a very good job on your thick, curly hair, though, the review team is partial to this Larmhoi brush. It’s a 3-in-1 brush that you can also use to blow dry or curl hair, but where it shines is in straightening the types of hair that’s been resistant to other tools.
The Larmhoi uses ceramic plates which heat up quickly (in just 30 seconds), and the dense arrangement of ceramic bristles on the brush transfer the heat efficiently and evenly. There are three heat settings on this hair straightener, with a low of 365° and a high of 450°. The low setting is fine for normal hair (although probably too high for very thin or brittle hair), but not all competitors can hit the sweet spot of 450° required for really thick and stubborn hair. That’s where the Larmhoi excels.
This model has the usual temperature lock, anti-scald and auto-shutoff safety features you’d expect. What it doesn’t have is the negative-ion function many people look for in a hair brush straightener. Considering the results the Larmhoi produces, though, we didn’t miss it.
The Larmhoi straightening brush can usually do its work in five minutes or less, leaving hair smooth and silky, for a price that will fit most budgets.
Features of the Larmhoi Ceramic Hair Straightener Brush:
The Groom+Style team worked flat out to bring you this review, we hope you enjoyed it! And, of course, once you have removed the curls you might actually want to add them back, if that is the case then one of our best curling irons will do the trick.
That is it for our updated list of the top 7 best hair brush straighteners for Apr. 2021 – if you are curious about our choices from previous years then continue reading.
FemJolie Electric Hair Straightening Brush
Note: Sorry this brush is currently out of stock on Amazon – we are checking to see what the problem is. Until then please check out our #2 choice.
This is the review team’s choice for the best hair brush straightener on the market, because of its convenience and flexibility.
The FemJolie flat straightening brush is convenient because of its lightweight, less than one pound. It’s extremely flexible because it allows you to select temperatures as low as 176° (too low for most users, but not bad for a brief touch-up) and as high as 450° (the right setting for those with very thick hair) in increments of 9°. The brush auto-locks at your selected temperature so you can’t burn your hair by mistake and so it automatically heats to the right temperature every time you use it; you can easily override the auto-lock if you choose.
The ceramic plate on the FemJolie heats in just a minute or two, and the silicone tips on the bristles are quite comfortable on the scalp and gentle as they detangle, straighten and de-frizz. It’s important to note that this straightening brush is only designed to work on clean, dry hair; you won’t see the results you expect if you use it right after jumping out of the shower, and because it’s a flat brush it won’t add volume to your hair the way a barrel model would.
Several other smart features impressed Groom+Style reviewers: there is an LED temperature indicator and an auto-shutoff function, the six-foot power cord swivels 360° to make the brush easy to use, and a glove is included to protect your hand against the straightener’s heat.
At a very reasonable price, the FemJolie is a great choice for straightening nearly any type of hair quickly and effectively and is easy to tuck into a bag or suitcase for use on the road.
Features of the FemJolie Electric Hair Straightening Brush:
Scalpmaster Ceramic Thermal Hair Straightener
*Currently this hair straightener is out of stock. We encourage you instead to take a look at one of the other excellent choices listed on this review page*
The Scalpmaster straightener looks like a flat iron but has two brushes mounted on the plates. The way you use this straightener is straightforward; you heat the hair by aiming a dryer into the vents on the back and pull the appliance through your hair. The short nylon bristles detangle and straighten the hair as you pull.
The Scalpmaster can be used without heat to detangle thick hair and is more effective on long, thick or frizzy hair (particularly African-American hair) than most of the other options the Groom+Style team has investigated. It is relatively inexpensive, and once you get the hang of using it, it’s quite effective in straightening hair.
An inexpensive option that is very effective on thick hair.
Features of the Scalpmaster Ceramic Thermal Hair Straightener:
Babyliss Pro Nano Titanium 2 Inch Rotating Hot Air Brush
The Babybliss is a rotating hair brush straightener, similar to Revlon Perfect Heat, however, it is made from titanium instead of ceramic and is more expensive. This model has three heat settings, but it does not have a cold shot button. Some believe the titanium makes a difference in the way their hair feels but the team doesn’t see it; we think the performance is virtually identical to the Revlon Perfect Heat.
