Flat roots, fine-to-medium hair, classic bouncy blowouts.
Pixie 20–28 mm · Bob 32–38 mm · Chin 38–45 mm · Shoulder 45–55 mm · Long 50–65 mm
What you need
- Round brush matched to your hair length
- Concentrator nozzle
- Clips for sectioning
- Cool-shot or short cooling pause
The step-by-step method
- Start with hair around 75–85% dry and divide it into clean, manageable sections.
- At the crown, place the brush under the root and elevate before moving into the mids.
- Follow the brush with airflow directed downward so the cuticle stays smooth while the roots lift.
- Use a half-turn through the mid-lengths to create bounce rather than wrapping the section multiple times.
- At the front, direct the brush away from the face for a softer, more open shape.
- Let the section cool for a few seconds before releasing it or brushing through.
Why this method works
- Volume comes mostly from elevation and tension at the root, not from heat alone.
- A larger diameter creates a broader curve, while section size controls how dramatic that curve looks.
- Cooling briefly helps the shape settle so the lift lasts longer.
Common problems and fixes
Use smaller sections and more elevation before moving up in barrel size.
Use less rotation, or move one barrel band larger.
Reduce how much hair you load onto the barrel and keep the brush moving.
If you want this lesson tied to your hair length and goal, use the size finder before you style.
Frequently asked questions
Is a bigger round brush always better for volume?
Not always. Bigger barrels create a broader shape, but they can become harder to control if the hair section is too short or too thick.
What if my hair is shoulder length but I still want more bend?
Stay in the shoulder-length range but move toward the smaller end of that band or use smaller sections.
Should I wrap the whole section around the brush?
Usually no. For a volume blowout, a controlled half-turn gives bounce without creating an over-curled finish.
