How to Use a Blow Dryer Brush (Step by Step)
Hey bestie! A blow dryer brush is one of the easiest ways to get a smooth, bouncy, salon-style blowout at home, without juggling a dryer in one hand and a round brush in the other. But like any tool, technique makes all the difference. This step-by-step guide shows you exactly how to use a blow dryer brush for volume, shine and less frizz.
Quick answer: To use a blow dryer brush, detangle and towel-dry your hair until it's about 70–80% dry, apply a heat protectant, and divide your hair into sections no wider than the barrel. Place the brush under each section at the root, hold for a few seconds for lift, then glide slowly to the ends while turning the brush, and finish each section with the cool setting to set the shape.
What does a blow dryer brush do?
A blow dryer brush (also called a hot air brush) pushes warm air through vents in a round or oval barrel while the bristles grip and tension your hair. That means it dries, smooths and adds volume at the same time. If you're still choosing one, our blow dryer brush guide covers barrel sizes and features.
What you'll need
- A blow dryer brush in the right barrel size for your length
- A detangling brush or wide-tooth comb
- A heat protectant
- Sectioning clips
- A soft or microfiber towel
- Optional: a lightweight serum for the ends
Which barrel size should you use?
| Barrel size | Best for | Result |
|---|---|---|
| Mini or compact | Bangs, short cuts, face-framing pieces | Precise root lift and control |
| About 2" | Short to shoulder-length hair | Root lift with a defined bend at the ends |
| About 3" | Long hair | Big, bouncy, voluminous blowouts |
How to use a blow dryer brush: step by step
Step 1: Wash and detangle
Start with clean hair. Detangle gently with conditioner still in your hair, working from the ends up. Knots catch in the bristles, so this step makes everything smoother later.
Step 2: Towel-dry gently
Squeeze and blot water out with a soft towel instead of rubbing, which can rough up the cuticle and cause frizz.
Step 3: Rough-dry to about 70–80%
Blow dryer brushes work best on damp hair, not dripping wet hair. Air-dry for a bit or rough-dry with your brush on a lower setting, pointing the airflow at the roots. Starting from damp saves time and limits how long your hair is under heat.
Step 4: Apply heat protectant
Mist a heat protectant evenly through mid-lengths and ends. It adds a protective layer between your hair and the heat.
Step 5: Section your hair
Clip your hair into four to six sections. Start at the bottom and work up. Each piece you style should be no wider than the barrel, so the bristles can grip every strand.
Step 6: Lift at the root
Place the brush under a section, right at the root, with the barrel angled up. Hold it there for a few seconds. This is where your volume comes from.
Step 7: Glide slowly to the ends
Keep light tension and pull the brush slowly down the length of the section. Moving slowly gives the warm air time to smooth the hair. At the ends, turn the brush under for a classic bend or out for a flip.
Step 8: Cool to set
Switch to the cool setting and pass over the section once more. Cool air helps lock in the shape and shine.
Step 9: Repeat and finish
Work through each section, then finish the front pieces last so they look freshest. Add a drop of lightweight serum to the ends if you like, and skip heavy products that weigh down volume.
Tips for different hair types
- Fine hair: use a lower heat setting, smaller sections and focus on root lift. Avoid heavy products before styling.
- Thick hair: rough-dry more thoroughly first and take thinner sections so the air reaches every strand.
- Curly or coily hair: detangle thoroughly and work in small sections. A high-speed dryer with a concentrator can do the heavy drying before the brush.
- Short hair or bangs: a mini barrel gets closer to the root and makes it easier to style face-framing pieces.
Common mistakes to avoid
- Starting on soaking-wet hair. It takes longer and means more time under heat.
- Using sections that are too big. The brush can't grip, and you'll end up with frizz.
- Rushing the glide. Slow and steady gives a smoother finish.
- Always using the highest heat. Start low and turn it up only if needed.
- Skipping the cool shot. It helps your blowout last.
- Letting hair build up in the bristles. Clean your brush and air intake regularly so airflow stays strong.

Frequently asked questions
Do you use a blow dryer brush on wet or dry hair?
Use it on damp hair that's about 70–80% dry. Hot air brushes are designed to finish and style damp hair, so rough-dry or air-dry first instead of starting from dripping wet.
How do I get volume with a blow dryer brush?
Place the brush under each section right at the root, angle it up and hold for a few seconds before gliding to the ends. Finish with cool air to set the lift.
Can I use a blow dryer brush every day?
Any heat tool used daily can stress your hair. Use a heat protectant, start on a lower setting, and give your hair heat-free days when you can.
How do I stop frizz when using a blow dryer brush?
Detangle first, use small sections, keep tension as you glide slowly, and finish each section with cool air. A tiny drop of serum on the ends also helps.
How often should I clean my blow dryer brush?
Remove hair from the bristles every few uses and check the air intake for lint regularly. A clean tool keeps airflow strong and heat even.
