Beauty Revlon One Step 2.0 Guide: Blowout Tips and Best Results
An educational guide from the Beauty AMZ research team. No hard sell, just what you need to know.
What the One-Step does
The Revlon One-Step is a hot air brush that combines a hair dryer with an oval styling brush. Hot air flows through the vented barrel while the bristles grip and shape the hair. The oval head with rounded edges creates volume at the roots and bends at the ends simultaneously. Nylon pins detangle while tufted bristles smooth the surface. Three heat settings plus a cool option cover fine to thick hair. The tool is designed for 120 volt US outlets and carries ETL safety certification. It turned the salon blowout into a 15 minute home routine and spawned the entire dryer brush category. It dries and styles in a single step. The oval brush adds volume as it dries. One pass replaces a whole blowout routine.
The perfect blowout routine
Towel dry hair until damp and apply heat protectant. Divide hair into sections, clipping the top away. Take the One-Step and place it at the roots of the bottom section for lift. Glide slowly down to the ends, rotating slightly to curl them under or out. Work through each section the same way, keeping the brush moving steadily. Use the cool setting on each finished section to lock the shape. For extra root volume, hold the brush under the roots for two to three seconds. Finish with a light shine spray, not heavy serum, to keep the bounce. The whole head takes 10 to 20 minutes. Towel dry until hair is damp, not wet. Work in sections from the nape upward. Roll the brush at the ends for bounce.
Tips for different hair types
Fine hair should use the low heat setting and move a bit faster to avoid over drying. A volumizing mousse on damp roots adds body that lasts. Medium hair can use medium heat and standard section sizes. Thick or coarse hair needs the high setting and smaller sections for full drying. Very long hair should dry in two stages: rough dry the roots first, then detail with the brush. Curly hair should stretch the curls with the brush for a smooth blowout, working in small sections. Always finish with cool air, which seals the cuticle and adds shine on every hair type. Fine hair needs the lowest heat setting. Thick hair can handle high heat safely. Curly hair should stretch sections first.
Maintenance and troubleshooting
Clean the brush head weekly to keep airflow strong; trapped hair reduces performance fast. If the tool smells hot, you are likely using too high a setting or moving too slowly. Let it cool between long sessions rather than running it nonstop. Never use it on soaking wet hair, which strains the motor and extends drying time. If volume falls flat by afternoon, your sections were too large or the hair was too wet. Store it unplugged in a drawer, not hanging by the cord. With basic care and correct technique, the One-Step delivers consistent blowouts for years. Clean the brush bristles after each use. Check the air intake for trapped hair. A clogged intake weakens all airflow. Monthly cleaning keeps it powerful.

Settings for Your Hair Type
The One-Step's heat settings should follow your hair, not your impatience. Fine or damaged hair belongs on the low or medium heat setting, since the brush's direct contact already delivers efficient styling and high heat on fragile hair causes breakage. Thick or coarse hair can use high heat, but start on medium until the hair is mostly dry, then finish on high for the smoothing passes. The common error is maxing the heat from soaking wet, which boils surface moisture into frizz before the interior dries. Let the tool do the work with steady passes rather than cranking temperature to compensate for rushing. Both the Black and Pink models share the same settings logic.
Diffuser Attachment Technique
Curly and wavy users often ignore the volumizer, but diffuser technique makes it relevant. Cup sections of hair into the diffuser bowl rather than blasting, since the airflow should dry the curl without disturbing the pattern. Hover diffuse the roots first for volume, then cup the lengths, and avoid touching the hair until it is fully dry, since handling wet curls creates frizz. Low heat with high airflow is the curly setting, which dries without roughing the cuticle. Pixie diffusing, holding sections in the bowl without moving, defines short curls without stretching them. Root clipping while diffusing adds lift that survives the day.
The Cold Shot Finish
The cool setting is not decorative, it locks the style the heat created. After each section is smooth and dry, finish with ten seconds of cool air while the hair is still wrapped on the brush, which sets the shape. Skipping this step is why blowouts fall flat by afternoon, since the style was never locked in. Run the cool setting over the whole head at the end as a final seal, which also calms any frizz the heat raised. If your model lacks a true cold shot, the lowest heat setting still helps compared to ending on high. The One-Step 2.0 technique guide covers the full routine, and the volumizer comparisons rank the models.
