8 Best Ceramic Round Brushes Worth a Look
Published 10/04/2026
A ceramic round brush has a ceramic barrel you use with a dryer. Barrel diameter changes the bend, and an extra-long body reaches further through a section. These are not heated by themselves. We kept ceramic round brushes and left boar-only rounds off. Here are eight ceramic round brushes worth trying.

Our picks, explained
Best 1.75-inch ceramic round
Olivia Garden Ceramic + Ion Round Brush 1.75 Inch CI-45
Olivia Garden Ceramic + Ion round thermal brush, 1.75 inch barrel, CI-45.
The CI-45 is Olivia Garden's Ceramic + Ion round with a 1.75 inch barrel, and the listing says it is not electrical. A mid barrel suits a soft bend on shoulder-length hair when you roll with a dryer. The ceramic coat is the heat surface. Skip the 2 1/8 inch CI-55 if this narrower barrel is the bend you want.
Why it makes the list
- 1.75 inches is printed as the barrel diameter.
- The brush is a thermal round, not a plugged-in styler.
What to keep in mind
- You still need a hair dryer.
- A 1.75 inch barrel is slow on very long thick hair.
Best 2 1/8-inch ceramic round
Olivia Garden Ceramic + Ion Round Brush 2 1/8 Inch CI-55
Olivia Garden Ceramic + Ion round brush with a 2 1/8 inch barrel, CI-55.
CI-55 uses the same Ceramic + Ion line with a 2 1/8 inch barrel, so the curl is looser than the 1.75 inch brush. The listing again says the brush is not electrical and the barrel is ceramic coated. Roll larger sections if you want volume more than a tight bend. Skip CI-45 if this wider barrel is the one in your hand.
Why it makes the list
- 2 1/8 inches is a wider barrel in the same line.
- Ceramic coating is stated on the listing.
What to keep in mind
- A wide barrel is awkward on a short bob.
- It will not curl as tight as the 1.75 inch brush.
Best extra-long 1 3/4-inch round
Olivia Garden Ceramic + Ion Speed XL 1 3/4 Inch
Olivia Garden Speed XL extra-long round brush, 1 3/4 inch barrel.
Speed XL keeps a 1 3/4 inch ceramic barrel and lengthens the brush body, which helps when the hair is past the shoulders. The listing points it at normal to thick hair and mentions ionic bristles with soft tips. It is still a dryer brush, not a hot tool you plug in. Skip a short-handle round if this extra-long body is what you need to reach the ends.
Why it makes the list
- Extra-long is the difference from the standard Ceramic + Ion.
- 1 3/4 inches is the stated barrel.
What to keep in mind
- A long handle needs more room in a drawer.
- Thick hair still takes sectioning. The length does not replace that.
Best 1 3/4-inch NanoThermic
Olivia Garden NanoThermic Ceramic + Ion 1 3/4 Inch NT-44
Olivia Garden NanoThermic ceramic round brush, NT-44, 1 3/4 inch.
NT-44 is the 1 3/4 inch NanoThermic, with a vented barrel the listing calls a turbo barrel. Vents change how the dryer air moves through the brush. Tourmaline ion is the bristle claim, and the brush is not electrical. Skip the 2 3/4 inch NT-64 if you want this smaller NanoThermic.
Why it makes the list
- NT-44 names the 1 3/4 inch NanoThermic.
- Extra vents are the point of this barrel.
What to keep in mind
- Vents can catch a fine section if you roll too fast.
- It is a professional-priced brush.
Best 2 3/4-inch NanoThermic
Olivia Garden NanoThermic Ceramic + Ion 2 3/4 Inch NT-64
Olivia Garden NanoThermic ceramic round brush, NT-64, 2 3/4 inch.
NT-64 is the wide NanoThermic, a 2 3/4 inch barrel with the same vented ceramic idea as the smaller one. A barrel this wide is for smoothing and root lift on longer hair. The listing says normal to thick hair. Skip NT-44 if you wanted the tighter 1 3/4 inch bend.
Why it makes the list
- 2 3/4 inches is the largest barrel in this set.
- The vented NanoThermic barrel is called out on the listing.
What to keep in mind
- A 2 3/4 inch brush is heavy in a small hand.
- Short layers will not wrap this barrel.
Best small 1.3-inch ceramic round
Osensia Small Ceramic Ionic Round Brush 1.3 Inch
Osensia small ceramic ionic thermal round brush, about 1.3 inch barrel.
Osensia's small round is listed around 1.3 inches, the tightest barrel on this page. A small ceramic barrel grips a bang or a face-framing piece. The title calls it a thermal brush for blow-drying. Skip a 2 inch brush if this short bend is the job.
Why it makes the list
- About 1.3 inches is the small-barrel size.
- Ceramic ionic is in the product name.
What to keep in mind
- A tiny barrel means many sections on long hair.
- It is the wrong width for a loose blowout.
Best 2-inch ceramic round
Osensia Large Ceramic Ion Round Brush 2 Inch
Osensia large ceramic ion thermal round brush with a 2 inch barrel.
The large Osensia lists a 2 inch thermal ceramic barrel and a lightweight handle. Two inches sits between the small Osensia and Olivia Garden's widest NanoThermic. Heat from the dryer is what the ceramic spreads. Skip the 1.3 inch Osensia if you wanted this wider roll.
Why it makes the list
- A 2 inch ceramic barrel is stated.
- The handle is described as lightweight.
What to keep in mind
- Two inches is still a lot of brush for a pixie.
- You need the dryer on while you roll.
Best 1.7-inch nano ceramic round
AIMIKE NaturaVol Nano Thermal Ceramic Round Brush 1.7 Inch
Aimike NaturaVol round brush listed at 1.7 inch with nano thermal ceramic.
Aimike calls this NaturaVol a 1.7 inch round brush and describes nano thermal ceramic with ionic bristles. That diameter is close to Olivia Garden's 1.75 inch, at a lower price. The listing also mentions an overall diameter around 2.5 inches once the bristles are included. Skip a boar-bristle round if you wanted this ceramic barrel.
Why it makes the list
- 1.7 inches is the size on the listing.
- Nano thermal ceramic is the barrel claim.
What to keep in mind
- Bristle length adds to the width you feel in the hair.
- A lower price does not include a dryer.
How we made this list
We shortlisted 8 picks for ceramic round brushes. Each one had to clear the same bar: a clear job fit, an Edyt Score from our editorial breakdown, and enough brand diversity that the list isn’t one house repeated seven times.
- Define the job. A ceramic round brush has a ceramic barrel you use with a dryer.
- Diversify brands. One hero SKU per brand unless a second lane clearly earns its spot.
- Score the formula. Rankings use Edyt’s editorial breakdown (ingredients, target fit, finish, and use case).
- Cut near-clones. When two SKUs told the same story, we kept the stronger score or clearer use case.
