Calling all curly-, wavy-, frizzy- or poofy-haired folks: My favorite hair tool of all time (and I've tried a lot) is on sale once again with early Black Friday pricing. The viral Revlon One-Step Volumizer Hot Air Brush, a TikTok favorite, is down to only $30, a 25% discount. The "miracle" blow dryer brush is now even cheaper than when I bought it in 2021. At that price it makes a great gift, sure. But it's also a good opportunity to treat yourself -- especially if you want to look sleek at that office holiday party.

Read on to see why I can't stop recommending this blow dryer brush to anyone who'll listen. And for more early Black Friday deals, check out our picks from Target, Best Buy, Amazon and Walmart. Plus, Ulta is having a blowout sale on beauty items, too.

Revlon's blow-dry brush does the work of a round brush and a blow dryer in one.

If there's one type of person I can't relate to, it's those with the manual dexterity to wrangle a round brush and a blow dryer in elegant choreography to achieve smooth, voluminous, salon-quality blowouts. (French braid wizardry is a close second.) Without the addition of a third arm, my options have always been flat-ironing all the personality out of my hair, curling it until I look like Dolly Parton or wearing it au naturel and having to reassure everyone that I haven't just been electrocuted. Or I suppose I could spend an arm and a leg at a blow-dry bar. But as I've established, I need to grow an arm, not spend one.

Enter the Revlon One Step Volumizer Hot Air Brush. I saw this hair tool trending on TikTok last summer, shortly after discovering that my side part and skinny jeans had gone out of style without my consent. I swiped through TikTok videos from trendy Gen Z'ers evangelizing the brush, which they said does the work of both a round brush and a blow dryer, effectively giving you one of your arms back. I was in a vulnerable state of geriatric millennial malaise, and the brush was on sale. I took the bait.

I identify as Type-2B wavy, with added frizz from a humid climate and postpartum regrowth flyaways. My hair is large and in charge, a veritable mane, a cousin to Cousin Itt. I went as Lorde for Halloween once, with creditable resemblance. I've impulse-purchased countless hair tools, accessories and products over the years -- Curlformers, Bumpits, Hairagami, the Revo Styler -- many of which didn't work properly on thick hair (the era of butterfly clips was particularly trying for me). And after falling down the TikTok rabbit hole, I fully expected the Revlon brush to be similarly disappointing. 

To my surprise, the learning curve was but a small berm, and my hair looked almost salon-sleek after just one try. I found a lot of overlapping muscle memory from years of curling iron use, and with the help of a few TikTok tutorials, I am now able to achieve both a bouncy, wavy look and a straighter style from the same tool. I like that curly styles with the Revlon brush aren't too Cowardly Lion and straight styles aren't limp either. And I love that I can dry and style my hair at once, saving not only time but also potential heat damage.

Here's how the Revlon One Step Volumizer Hot Air Brush works: Like a round brush, the One-Step Volumizer is round -- elliptical, actually -- and covered with soft bristles for smoothing sections of hair as it passes over. And like a hair dryer, the tool blows hot air from inside the brush, drying your hair and setting the curl (with three heat settings) as it goes. Unlike competitors like the Dyson Airwrap, Revlon's two-in-one doesn't come with any attachments, and it won't "auto-wrap" your hair. It's also only a fraction of the price.

These days I still battle a bit of frizz at my roots -- Revlon's large barrel does make it difficult to get very close to your scalp -- but it's nothing a once-over with a curling iron and a dollop of product can't remedy. Other than that, I've scarcely used any other hair tools since purchasing the Revlon blow-dryer brush. And not a single person has asked if I've recently been electrocuted.
