Our verdict

The Single Shot is the Double Shot's round-barreled sibling, and the shape change is the whole story: at 2.25 inches it grips short hair, bangs and bob lengths that ovals cannot tension, while keeping Drybar's ionic smoothing. Premium priced and slower on long hair, it is the specialist pick for shorter styles that want a true blowout bend.

What we like

  • 2.25 inch round barrel reaches roots, bangs and bob lengths the big ovals skate over
  • Ionic technology reduces frizz and adds shine as it dries
  • Nylon and tufted bristles grip for tension without pulling
  • Three heat settings including a cool option for setting the finish

What to watch out for

  • Round barrels ask for more sections than ovals on medium hair
  • Premium Drybar pricing for a single-purpose tool
  • Not the lightest travel option in this guide

What owners report: Drybar The Single Shot Round Blow-Dryer Brush

Synthesized from recurring themes in long-term owner feedback.

Most praised

  • The round barrel finally gives short hair a real blowout shape instead of a flattened oval pass
  • Bangs and fringe come out polished instead of blown sideways
  • Ionic finish leaves ends smooth enough to skip the flat iron on most days

Common complaints

  • Sectioning short hair around a round barrel takes practice before it gets fast
  • Owners with long hair find it slow and reach for the oval instead
  • The premium price stings for a tool some use only on fringe and roots

Who it is for

Short to medium hair owners who want salon round brush results, especially on bobs, lobs, bangs and layers.

Why round matters

Oval volumizers smooth and lift, but they cannot wrap a section the way a round barrel does. The Single Shot's 2.25-inch round head curls ends under, bends layers and shapes a fringe, which is why Drybar positions it for shorter hair and bangs.

Ionic smoothing

Drybar's Ionic Technology is the same frizz-reducing, shine-adding system as the Double Shot, delivered here with strategically placed vents for maximum airflow and a nylon and tufted bristle mix that tensions without snagging.

Settings and handling

Three temperature settings, cool, medium and high, cover fragile fringe through coarse roots, and the ergonomic body keeps the 1100-watt tool manageable through a full short-hair routine. Long, thick hair will find the round barrel slow going compared with the oval.

Questions, answered

What barrel size is the Single Shot?

2.25 inches, a true round barrel sized for shorter hair, bangs and bob to lob lengths.

How is it different from the Double Shot?

Shape and brief: the Single Shot is round for bend and fringe control on shorter hair; the Double Shot is oval for faster smoothing and volume on longer hair. Both use Drybar's ionic technology.

Does it reduce frizz?

Yes, its ionic technology is designed to reduce frizz and add shine, and the bristle tension seals sections as they dry.
