The Olivia Garden NanoThermic is an unheated round brush with a ceramic and ion coated barrel that absorbs heat from your dryer and holds it, so the brush itself does the shaping while the dryer does the drying. The barrel is vented to let airflow through rather than trapping it, and the bristles are a tuft-and-nylon mix that grips a section without snagging. The handle is heat-resistant with a soft grip, which matters on a blowout that takes twenty minutes. It is a salon-standard tool rather than a consumer gadget, and there is no cord or power involved. Best fit: anyone learning to do their own blowout, or anyone whose current round brush keeps letting the section slip.
Pros
- Ceramic and ion barrel holds dryer heat, which cuts how long a section takes
- Vented barrel lets airflow through instead of trapping it against the scalp
- Bristle mix grips a section firmly without ripping on the way out
- No cord and no power, so nothing to break or replace
Cons
- It is a plain brush, not a hot tool, so it only works as fast as your dryer does
Frequently asked questions
Does this brush heat up on its own?
No. It has no power source. The ceramic barrel absorbs and holds heat from your blow dryer, which is what speeds up the styling.
Which barrel size should I get for long hair?
Larger barrels create looser volume and work better on long hair, while smaller barrels give more bend and suit shorter cuts or bangs.
Will the bristles pull on fine hair?
The tuft-and-nylon bristle mix is designed to grip without snagging, and fine-hair users generally report less pulling than with all-boar brushes.
Can I use it on wet hair?
Yes, this is a blow-drying brush meant to be used on damp hair as you dry. Detangle first with a wide-tooth comb to reduce tension.
