The Revlon One-Step became one of the most-reviewed beauty products on all of Amazon after going viral for genuinely cutting blowout time and effort compared to a separate dryer-plus-round-brush routine — and years later it’s still a top recommendation across beauty outlets, not just a passing trend.
Our Pick: Revlon One-Step Volumizer — around $59.99

What Owners Actually Say
Owners with years of experience with other styling tools describe it as a genuine routine-changer. One user who has used it since 2019 across multiple hair lengths said, “this hairdryer is SO easy, and looks so professional, I started getting compliments.” Another longtime round-brush-and-dryer user admitted: “I am in shock” at how well it replaced her usual blowout routine.
The most common complaint is unit longevity — a couple of owners reported their unit dying or randomly losing heat after a year or two of use, with one having to repurchase a replacement. A few reviewers also noted the same product is sometimes cheaper at other retailers, so it’s worth comparing prices before buying, and it’s a good idea to register the warranty in case the heating element fails early.
Pros
- Combines a hair dryer and round brush into a single tool, cutting blowout time roughly in half for most users
- Oval brush design smooths hair while adding volume at the roots simultaneously
- Ceramic and tourmaline coating reduces frizz and heat damage compared to a basic dryer
- Lightweight enough for most users to style one-handed, unlike a separate dryer-plus-brush routine
Cons
- Non-detachable brush head means less versatility than separate dryer-and-brush combos for different hair lengths
- Best suited to medium-to-long hair — reviewers with very short hair report less benefit from the round-brush design
Best Brush Dryer for Straight Hair Volume: What Makes This One Work
Not every brush dryer is built for the same hair type. This one earns its “best brush dryer for straight hair volume” reputation because the oval brush head smooths the cuticle while adding lift at the roots in a single pass — a combination that works especially well on straight-to-wavy hair that falls flat by midday. Curlier textures generally see less benefit without a diffuser attachment.
FAQ
- Does it work on curly or coarse hair? Owner reports are mixed — it works best for smoothing and adding volume to straight-to-wavy hair; very curly or coily hair textures may need a diffuser attachment this model doesn’t include.
- How long does the motor typically last? Long-term owner reviews commonly report 2-4+ years of regular use before performance noticeably drops, in line with most mid-range styling tools.
- Is it good for short hair? Reviewers with short hair report less dramatic results, since the oval brush needs enough length to wrap around — it performs best on hair from chin-length to long.
- Does it damage hair? The ceramic and tourmaline coating is designed to reduce frizz and heat damage compared to a standard dryer, though using a heat protectant and the lowest effective setting still helps limit wear from regular hot-tool use.
- What makes this a good brush dryer for straight hair volume? The oval brush shape smooths hair while lifting the roots in the same pass, which is why it’s best suited to straight-to-wavy hair looking for volume rather than curl definition.
- How does it compare to using a separate blow dryer and round brush? Combining the dryer and brush into one tool cuts typical blowout time roughly in half, since there’s no switching between a diffuser and a separate brush mid-style.
