Beauty Revlon One-Step 2.0 Guide: Features, Use, and Care Tips
An educational guide from the Beauty AMZ research team. No hard sell, just what you need to know.
What the 2.0 upgrade changed
Revlon listened to user feedback for the 2.0 generation. The barrel shrank to 2.4 inches for better root access. The head now detaches for travel and storage. Bristles gained charcoal infusion for smoother detangling. The motor was rebuilt for longer life. A fourth heat setting added finer control. Each change solves a real complaint about the original.
How the one-step blowout works
The tool combines a dryer with a round brush in one device. Hot air flows through the vented barrel as you brush. The oval shape smooths while the rounded edges add volume. You style damp hair directly, skipping the separate dryer step. Sections dry and shape at the same time. The result is a bouncy blowout in about half the time.
Step-by-step blowout technique
Towel dry hair until just damp. Apply heat protectant evenly. Divide hair into manageable sections. Place the brush under a section near the roots. Glide slowly toward the ends while rotating slightly. Repeat until the section is dry and smooth. Finish with the cool setting to lock the style. Practice makes the motion natural.
Best settings for each hair type
Fine hair thrives on low or medium heat. The smaller barrel gives lift without over-drying. Medium hair can use medium heat for efficient styling. Thick or coarse hair handles high heat for faster results. Curly hair should detangle fully before starting. Always finish with cool air for shine.
Maintenance that extends its life
Clear bristles of hair after every use. Product buildup wipes off the barrel when cool. Store the detachable head separately to avoid pressure. Keep the air intake clear of dust. Never wrap the cord around the hot unit. These habits easily double the working life.
Who should buy the 2.0
It suits anyone who blow dries at least twice a week. Travelers love the detachable design. Short to medium hair gets the most from the smaller barrel. Salon blowout lovers save real money over time. If you already own the original and love it, the upgrade is optional but nice.

Noise Reality Check: Drying With Thin Walls or a Sleeping Baby
Hot-air brushes like the Revlon One-Step are loud, typically running in the high 70s to mid 80s decibels, which is the range where thin apartment walls and sleeping babies become real constraints. No mainstream hot-air styler is genuinely quiet, the motor plus forced air through a brush head sets a noise floor that engineering cannot dodge at this price. The practical variables are drying speed, a faster dry means fewer loud minutes, and time of day.
The workarounds are scheduling and technique. Rough-dry with a regular dryer on low, which is often quieter per minute, then finish with the One-Step for the styling pass only, cutting loud minutes significantly. For genuinely noise-sensitive situations, the quietest picks are low-wattage dryers with concentrators, which trade speed for sound. If noise is a daily constraint rather than an occasional one, our Andis 1875 dryer guide covers salon power at lower price points with noise notes.
The Burning Smell: Filter Cleaning vs Tool Failure
A burning smell from a hot-air brush has two completely different meanings, and distinguishing them saves either a cleaning session or a replacement purchase. Lint and hair trapped in the rear filter restrict airflow, the motor overheats, and the smell is dust burning off, which resolves with filter cleaning. A sharp electrical or melting-plastic smell that persists after cleaning means component failure, and the tool should be retired, not pushed through.
Filter cleaning frequency for regular users is monthly, remove the rear filter cover, clear the lint with a soft brush, and check the brush head for wrapped hair that strains the motor. Never use the tool with a wet filter or run it without the filter in place. If the tool is over two years old with heavy use and the smell is new, replacement is the rational call over repair.
