FAQs
What makes the NanoThermic Speed XL good for blowouts?
The NanoThermic Speed XL has an extra-long barrel that dries hair 25% faster, with a ceramic-coated barrel that heats up faster and retains heat longer. Extra-large vents reduce drying time, and heat-resistant ionic bristles help you create long-lasting, smooth blowouts.
Is this a good round brush for long hair?
Yes, the NanoThermic Speed XL's extra-long barrel gives long hair more surface to wrap, so you can work through it faster. Use a wider barrel for loose, smooth movement or a narrower one for more defined bends and curls.
Does the NanoThermic Speed XL help reduce frizz?
Yes, the NanoThermic Speed XL's heat-resistant ionic bristles hydrate the cuticle, eliminate frizz and flyaways and add more shine to the hair. The bristles are also anti-static, and the ceramic-coated barrel retains heat longer for a smoother finish.
What's special about the wavy bristles on this brush?
The bristles' special wavy shape makes them more heat resistant, so they hold up to blow-drying heat. Their tips are polished and rounded to be gentle on hair and scalp, and the bristles are ionic and anti-static to help control frizz and flyaways.
Which barrel size should I choose for my hair?
The NanoThermic Speed XL comes in 1", 1 1/4", 1 3/4", 2 1/8" and 2 3/4" barrels. The smallest suits short hair and tight curls, the mid sizes suit medium to longer length, and the largest suits the longest hair and biggest, softest waves.
Is the NanoThermic Speed XL good for fine hair that needs volume?
Yes, the NanoThermic Speed XL is designed to create curls, add volume or straighten hair, and it is lightweight for effortless styling. On fine hair, a smaller barrel lifted at the roots builds more volume, while extra-large vents reduce drying time.

Absolutely the BEST round brush I ever used
This was my first experience with Olivia Garden products and I have to say, I am in love with Olivia Garden hair products. I want more! I used this product Nanothermic Speed XL Thermal Brush 1 ¾" 44mm on my hair. It did very well. Love the extra-long barrel. My hair did not get caught or pulled out...

Upon recommendation of my hair stylist I bought this brush! GAME CHANGER! A rolling brush I can use myself without my hair tangling up in it and the torture! This brush rolls easily in drying, handle easy to hold while drying and the best part is the bristles don't grab and tangle hair while drying...

Poor quality and no guarantee from Ulta
I bought this round brush online from Ulta. It delivered on 6/9 and broke in half on 6/12. Ulta would not issue an exchange or store credit since it broke past the 60 day window. Very disappointed in the product quality and Ulta.

Soft and bouncy waves
My hair dries fast and use my Dyson with this game changer brush. I noticed my hair dries fast and it doesn't pull out my hair like most blow out brushes.
I absolutely love this brush

I was wondering how noticeable of a difference this brush, allegedly designed to protect the hairs from heat, would make. You see, I left my previous round brush in Florida when I was visiting my parents and thought instead of having them ship it back I would just purchase a new brush and used the reviews to guide my decision. "$35 for a round brush seems steep," I thought to myself but I think my previous brush was from a grocery store or something and this new baby really seems to do a protec on the hairs. I like the huge barrel and it doesn't get caught on my hair like the previous brush. Also does great in terms of creating volume. Would recommend!
