- Amazon Prime Day 2025 is almost over. The four-day sale began on Tuesday, July 8, and will run through Friday, July 11.
- Right now, the Revlon One-Step Hair Dryer and Volumizer, the Good Housekeeping Beauty Lab's best value hair dryer brush, is 60% off.
Despite my best efforts, I never considered myself to be good at doing my own hair — until I purchased the Revlon One-Step Hair Dryer and Volumizer. It changed the game for me. Luckily, for Amazon Prime Day 2025, this Good Housekeeping Institute-tested hair tool is 60% off, making it under $30.
While this is a few dollars shy of the record-low price — and it's often on sale in the $30 range — $28 is still a great deal if you're hoping to buy a wallet-friendly hair tool during Amazon's biggest sale of the year.
In the five years I've owned this blow dryer brush, it has transformed everything from waist-length locks to my current shoulder-grazing style with ease, delivering results equivalent to a professional blowout for a fraction of the cost. Our pros named the 1.0 version the best value blow dryer brush, citing its fast drying times and unique shape.
"The smart design of the brush is what makes this tool unique," said Sabina Wizemann, Good Housekeeping Institute Beauty Lab director. "The oval shape allows for two different types of brushes to work together simultaneously: The longer, flatter side acts as a hair-straightening paddle brush, while its rounded corners lift the hair from its roots and create volume like a round brush does."
Speaking of volume, that's where this tool really shines. My hair is rather thin and straight, so before using this brush, I would have to blow-dry it, then use rollers to give my hair the oomph I wanted. With this two-in-one tool, I can achieve a bouncy blowout in just a few minutes.
Director of Editorial Commerce Jessica Teich also loves the results when using this tool on her curly hair. "It makes quick work of transforming my curly, frizz-prone hair into a silky-smooth style," she said.
Just note that this tool can potentially be damaging over time due to its high heat levels. Our Beauty Lab recommends avoiding use when your hair is soaking wet and suggests pairing it with a heat protectant.
With over 395,000 five-star reviews on Amazon, this hair tool is a cult favorite that's worth trying. Although it's often overlooked, we're not sure how long this under-$30 deal will last.
