The Best Hair Dryer Brush: 3 Picks for an At-Home Blowout

A classic oval volumizer, a titanium brush with a bigger barrel and a lighter ionic brush with mixed bristles, plus how to limit heat damage.

By BeautyFounded Editorial Team · Updated · 7 min read

The best hair dryer brush for most people is the REVLON One-Step Volumizer: a 2.8-inch oval barrel that dries and smooths in one step, with Cool, Low and High settings. For a bigger, rounder blowout, the L'ANGE HAIR Le Volume has a 75 mm titanium oval barrel. If you want a lighter tool for detangling as you dry, the Conair All-in-One Hot Air Brush has 136 flexible bristles and an ion generator.

Any hot tool can damage hair if you overdo it. The American Academy of Dermatology (AAD) suggests air-drying when you can and using the lowest heat setting when you blow-dry.

How we picked

We searched Amazon's Beauty department for hair dryer brushes, set aside sponsored results, and chose three oval or paddle-style hot air brushes from established brands, each for a different need. Our curling iron guide covers curling tools, and our dry shampoo guide helps stretch a blowout between washes.

Every product detail comes from the Amazon listing on the day we checked it. Brand claims about frizz, shine and speed are labeled as claims. Heat advice comes from the AAD and a 2011 study in the Annals of Dermatology.

REVLON One-Step Volumizer black oval hair dryer brush
1. Best Overall

REVLON One-Step Volumizer Hair Dryer and Styler, 2.8 in

Shipped and sold by Amazon.com

This is the classic oval dryer brush. Revlon says the 2.8-inch oval barrel smooths hair while its rounded edges create lift, volume and curled ends, and that you use it on damp hair to dry and style at once, without juggling a separate dryer and round brush.

It has three settings, Cool, Low and High, so you can follow the AAD's advice to use the lowest heat that works. Revlon recommends this larger barrel for mid-length to long hair; nylon pins and tufted bristles grip the hair.

What the listing says

  • 2.8-inch oval barrel
  • Cool, Low and High settings
  • Nylon pins and tufted bristles
  • Recommended by Revlon for mid-length to long hair

Keep in mind

  • Revlon itself steers shorter hair toward a smaller barrel
  • Start on Low; the AAD recommends the lowest heat setting
  • Use on damp, not soaking wet, hair, per the listing

Best for: Mid-length to long hair and a classic, high-volume blowout.

L'ANGE HAIR Le Volume titanium blow dryer brush
2. Best Big-Barrel Blowout

L'ANGE HAIR Le Volume 2-in-1 Titanium Blow Dryer Brush

Sold by L'ange Hair Inc. and shipped by Amazon

Le Volume has the biggest barrel of our three: a 75 mm oval with a titanium finish that L'ANGE says spreads heat evenly. The brand says its 360-degree airflow lifts hair at the root and its frizz-control technology seals the cuticle for a smooth, shiny finish.

It has adjustable heat settings and a 360-degree swivel cord to stop tangles. L'ANGE says it suits fine, thick, wavy and curly hair.

What the listing says

  • 75 mm oval barrel with titanium finish
  • 360-degree airflow, per L'ANGE
  • Adjustable heat settings
  • Swivel cord

Keep in mind

  • The frizz-sealing and salon-blowout claims are L'ANGE's
  • A large barrel can be awkward on short hair
  • The listing's shipping weight is the heaviest of our three; the tool weight isn't stated

Best for: Long or thick hair when you want a big, round blowout.

Conair All-in-One ionic hot air brush with mixed bristles
3. Best for Detangling

Conair All-in-One Hot Air Brush, Ionic, 1000W

Shipped and sold by Amazon.com

Conair's brush is built around detangling: 136 flexible, epoxy-tipped nylon bristles that the brand says glide through wet or dry hair without pulling. It dries, detangles and smooths in one step, so you can use it on towel-dried hair straight from the shower or between wash days.

Conair says its ion generator helps reduce frizz and flyaways. The listing gives 1,000 watts, multiple heat settings, a cool shot button and a 6-foot cord, and says it weighs 1.8 pounds.

What the listing says

  • 136 flexible, epoxy-tipped bristles
  • Ion generator, per Conair
  • Multiple heat settings and cool shot
  • 6-foot cord; 1,000 watts

Keep in mind

  • The bullet says 1.8 lb but the spec lists 1.61 lb
  • Frizz reduction is Conair's claim
  • The listing doesn't give a barrel diameter; check the photos for the head shape

Best for: Hair that tangles easily, and quick between-wash-day touch-ups.

What to look for

Barrel size

Bigger barrels make bigger, rounder blowouts; Revlon recommends its 2.8-inch barrel for mid-length to long hair.

A low setting

The AAD recommends the lowest heat setting when you blow-dry. All three picks have more than one setting.

Bristles

Nylon pins grip for smoothing; flexible tipped bristles help detangle.

Cord and weight

A swivel cord helps stop tangles, and a lighter tool is easier on your arm in a long session.

The bottom line

  • Best Overall: REVLON One-Step Volumizer: a 2.8-inch oval barrel with three settings.
  • Best Big-Barrel Blowout: L'ANGE HAIR Le Volume: a 75 mm titanium oval barrel.
  • Best for Detangling: Conair All-in-One: 136 flexible bristles and an ion generator.

Questions, answered

Is a hair dryer brush bad for your hair?

Any heat can damage hair. In a 2011 study in the Annals of Dermatology, damage to the hair's outer cuticle rose as drying temperature went up and the dryer moved closer to the hair. The AAD suggests using the lowest heat setting and air-drying when you can.

Can I use a hair dryer brush on wet hair?

Use it on damp hair. Revlon says to use the One-Step on damp hair, and Conair says its brush can go on towel-dried hair straight from the shower.

Which barrel size should I choose?

Revlon recommends its 2.8-inch barrel for mid-length to long hair. A bigger barrel, like L'ANGE's 75 mm oval, makes a rounder, fuller blowout but can be awkward on short hair.

How often can I use a hair dryer brush?

The AAD suggests limiting heat styling and, for hot combs and curling irons, using them about once a week or less. Air-drying partly first and using a low setting both reduce heat exposure.

Do ionic hair dryer brushes reduce frizz?

Conair says its ion generator helps reduce frizz and flyaways. That is the brand's claim; we didn't find independent testing.
