Revlon One-Step Volumizer Showdown: Our Top Two Compared

Heat and Speed Settings Mapped to Hair Type

Specific heat and speed combinations for hair types are never mapped, so here is the guide for the One-Step Volumizer. Fine or damaged hair, low heat, low speed, because fine hair dries fast and high heat causes disproportionate damage. Normal medium hair, medium heat, high speed, the high airflow dries efficiently while medium heat limits damage. Thick or coarse hair, high heat, high speed, because dense hair needs the thermal power to dry the interior.

The damage-avoidance rationale is that airflow does more drying work than heat, so maximizing speed before maximizing heat is always the safer path. The Volumizer Plus's improved motor matters here, better airflow means effective drying at lower heat settings. Sectioning matters too, working in four to six sections gives the brush the tension it needs for smoothness, while unsectioned drying just moves hot air around. For the technology behind the heat, our BaByliss dryer guide explains the systems.

The 80 Percent Rule: Rough-Dry Then Style

The rough-dry-then-style technique never gets real timing, so here it is. Rough dry with the volumizer until hair is about 80 percent dry, which means it feels dry to the touch but still cool in the interior sections. Only then begin the styling passes, sections wrapped around the barrel with tension for smoothness and volume. Styling soaking-wet hair wastes time, causes more heat damage, and produces frizzier results.

How dry each section should be before the styling pass is the detail that matters, the section should feel dry on the surface with slight dampness inside. Two to three styling passes per section suffice at this dryness, more passes mean the section was too wet. The cool shot, if your model has one, sets each section after styling, a blast of cool air locks the shape. For hot-air styling technique broadly, our air styler picks cover the method.

Dryer Maintenance: Filter Cleaning and Burn Smells

Dryer maintenance is never covered honestly. The lint filter on the Volumizer needs cleaning every two to three weeks with regular use, a clogged filter forces the motor to work harder, reducing airflow and increasing heat, which is the actual cause of many performance complaints blamed on the tool aging. Remove the filter cover, clear the lint with a soft brush or old toothbrush, and replace it.

The burning smell question has a real answer. A slight hot smell on first uses is normal manufacturing residue burning off. A persistent burning smell after weeks of use signals either a severely clogged filter or motor trouble, clean the filter first, and if the smell continues, stop using it, because motor failure can become a safety issue. Lint removal technique matters, never use water on the filter area, dry brushing only. For pro-grade dryer longevity, our BaByliss Pro guide covers maintenance schedules.

Root lift technique deserves a specific mention. For maximum volume, direct the brush upward at the roots, holding each section up and away from the scalp for a few seconds before smoothing down the lengths. This upward-first motion creates the lift that distinguishes a bouncy blowout from merely straight dried hair.
