The REVLON One-Step Volumizer is a hybrid hot air brush that combines the functions of a blow dryer and styling brush into one tool. It is designed for people with mid-length to long hair who want faster styling without the learning curve of managing separate tools. The 2.8-inch oval barrel is specifically engineered for maximum coverage and efficiency.
What sets this tool apart is its ability to deliver genuine salon-quality results in minutes. Users consistently report that hair dries faster, looks smoother and shinier, and holds volume without frizz. The nylon pins and tufted bristles provide the tension needed to style effectively, while the rounded edges help create volume and shape curled ends. The three heat settings (Cool, Low, High) allow customization based on hair type and desired finish, making it suitable for various styling needs.
The design is thoughtfully constructed for comfort and control. At just 1.5 pounds and measuring 4.1 x 11.4 x 10.1 inches, it is easy to hold and maneuver through hair without fatigue. The ergonomic shape fits naturally in the hand, and the fixed barrel eliminates the need to swap attachments, streamlining your routine significantly.
One consideration is that this tool performs best with consistent care rather than heavy daily use. While many users report enjoying this dryer for 7+ years, some note that intensive daily styling may cause it to overheat over time. Using a heat protectant product and varying heat settings can help extend its lifespan. Additionally, the fixed 2.8-inch barrel works best for mid-length to long hair and may be less practical for very short styles.
Overall, the REVLON One-Step Volumizer delivers exceptional value for anyone seeking to simplify their styling routine and achieve professional-looking results at home. Its combination of speed, ease of use, and consistent quality makes it a standout choice in the hot air brush category.
The REVLON One-Step Volumizer is best suited for people with mid-length to long hair who want to reduce styling time and achieve volume without frizz. If you currently use a separate blow dryer and brush, this tool will streamline your routine and likely cut your drying time in half.
Consider this tool if you have limited styling experience or want salon-quality results without professional techniques. The design is forgiving and produces great results even for beginners. However, if you have very short hair or need precise detail work, the 2.8-inch barrel may be too large for your needs. The smaller 2.4-inch Volumizer Plus or the 3-in-1 Multi-Styler with attachments might be better alternatives.
For best results, use this tool on damp (not soaking wet) hair. Apply a heat protectant product before styling to minimize heat damage and extend the tool's lifespan. Use the Low or Cool setting when possible to reduce stress on hair, especially if styling daily. This approach will help you achieve the healthiest, most stunning blowouts while maximizing durability.
Buying Guide: What to Look for in a Round Brush for Thick Hair
Barrel Size and Material
For thick hair, a medium to large barrel (around 1.7 to 2.5 inches in diameter) provides enough surface area to dry sections efficiently and create smooth volume. Ceramic or nano thermal barrels distribute heat evenly, reducing hot spots that can damage dense hair. Vented barrels also improve airflow, cutting drying time significantly.
Bristle Type
Boar bristles are ideal for thick hair because they help distribute natural oils from the scalp down the hair shaft, reducing frizz and adding shine. Mixed bristles (boar and nylon) offer a balance of grip and glide, making it easier to detangle without pulling. Look for ball-tipped nylon bristles to prevent snagging.
Heat Technology
Ionic technology emits negative ions that seal the hair cuticle, minimizing frizz and static. Combined with ceramic or copper coatings, these brushes heat evenly and speed up drying. This is especially valuable for thick hair, which retains moisture longer. For more insights on ionic brushes, see our top round brush for volume guide.
Handle and Barrel Design
A comfortable, non-slip handle reduces hand fatigue during long styling sessions. Barrel size matters too: a 1.7-inch barrel works well for medium to long thick hair, while larger barrels (2.5 inches or more) are better for creating loose waves and adding volume. Ergonomic handles with rubber grips are a smart choice.

Buying Guide
Barrel Size for Thick Hair
Thick hair often requires a barrel that can wrap sections without overcrowding. A 1.7-inch barrel is versatile for most lengths. For shorter thick hair, a smaller barrel (1.5 inches) offers more control. If you prefer loose curls, go for a 2.5-inch barrel.
Bristle Type Matters
Boar bristles are gentle on thick hair and help tame frizz. Nylon bristles provide better tension for smoothing. Many top brushes combine both. Avoid plastic bristles that can cause breakage. For a deeper dive, read our best boar bristle brush article.
Heat and Ionic Features
Ceramic and ionic technologies reduce drying time and static. Copper coatings improve heat transfer, which is great for thick hair that needs more heat. These features also help lock in moisture. If you struggle with tangles, our best detangling brush for thick hair guide may also help.
Ergonomics and Grip
Long styling sessions require a brush that won’t slip. Look for rubberized, contoured handles. Lightweight designs reduce wrist strain. A comfortable grip lets you focus on technique rather than holding on.
Final Thoughts
After evaluating these options, the AIMIKE Round Brush for Blow Out stands out for its high rating, nano thermal ceramic ionic technology, and natural boar bristles that add shine and reduce frizz on thick hair. For those who prefer a faster drying experience with a trusted brand, the Conair Round Hair Brush, Quick Dry Copper offers excellent heat transfer and snag-free styling at a great value. Both choices will help you achieve smooth, voluminous blowouts without the salon price tag.
