If you’ve ever tried to recreate a salon blowout at home with a round brush, you know the struggle. Your brush gets tangled. Your arms ache. The results look nothing like what your stylist achieves. Mastering the round brush blowout technique takes practice, but with the right tools and methods, you can get salon-quality results from your bathroom.
Key Takeaways
Mastering the round brush blowout takes practice, but it’s absolutely achievable at home with the right approach. Start with the proper tools: a large round brush with mixed bristles and a powerful blow dryer with a concentrator nozzle.
Follow the roll and follow technique, always directing heat downward and using the cool shot to set each section.
If you’re struggling after a few attempts, don’t hesitate to book a hands-on lesson at Artists & Architects Salon in Ridgewood. Our stylists can show you the technique in person, recommend tools specific to your hair type, and help you troubleshoot whatever’s not working. Sometimes the difference between frustration and success is just one professional tip tailored to your specific hair.
Tools You Need for a Round Brush Blowout
Before you start, gather the right tools. Using proper equipment makes the difference between a frustrating hour-long struggle and a smooth 30-minute styling session. Here’s what you’ll need.
Choosing the Right Round Brush
Not all round brushes work the same way. The material, bristle type, and barrel size all affect your results.
Material matters:
- Boar bristles create the most volume and shine but grip hair firmly, which can cause tangles if you’re not careful
- Nylon bristles are gentler and better for taming frizz and flyaways
- Ceramic barrels heat evenly and work well for fine hair that struggles to hold curl
- Mixed bristles (boar and nylon) offer the best of both worlds for most hair types
Size guide:
The barrel diameter determines your curl size and who the brush works best for:
- Small (1–1.5 inches): Short hair or tight curls
- Medium (2–2.5 inches): Shoulder-length to mid-back hair
- Large (3+ inches): Long hair or maximum volume
Pro tip from Artists & Architects Salon stylists: Start with a large brush if you’re a beginner. Smaller brushes tangle more easily, and you’ll spend more time fighting knots than styling your hair.
Heated Round Brush vs Traditional Round Brush
Heated round brushes (like the Revlon One-Step) combine the blow dryer and brush into one tool, which sounds convenient. A heated round brush blowout is faster and easier for beginners, but you’ll sacrifice some control and volume compared to using separate tools.
When to use a heated round brush:
- You’re new to blowouts and get frustrated easily
- You want a quick 15-minute style
- You have straight or slightly wavy hair
When to use a traditional round brush:
- You want maximum volume and professional results
- You have curly or thick hair that needs serious straightening power
- You’re willing to invest time learning the technique
For this tutorial, we’re focusing on the traditional round brush method because it delivers better results once you master it. But if you’re struggling, a heated round brush is a solid stepping stone.
Best Blow Dryer Features for Round Brush Blowouts
A quality blow dryer cuts your styling time in half and protects your hair from damage.
Essential features to look for:
- High wattage (1800W or higher) for faster drying. The longer you apply heat, the more damage you risk
- Multiple heat settings so you can adjust based on your hair type and the section you’re working on
- Cool shot button that locks in your style (this feature is non-negotiable)
- Lightweight design because your arms will get tired holding a heavy dryer for 30+ minutes
- Concentrator nozzle that directs airflow precisely where you need it
Essential Products
You’ll need four key products to protect your hair and make your blowout last:
Heat protectant shields your strands from temperatures up to 450 degrees. Apply this first, before any other products, to prevent damage and reduce frizz.
Volumizing mousse or spray goes at your roots to create lift that lasts. Without this, your roots will fall flat within hours, no matter how well you blow dry.
Smoothing serum (lightweight formula only) controls frizz without weighing hair down. A dime-sized amount is plenty—too much makes your hair look greasy.
Flexible-hold hairspray keeps everything in place while still allowing natural movement. Skip the stiff, crunchy formulas.
Step-by-Step: Round Brush Blowout Technique
Now for the actual technique. Follow these steps in order, and don’t skip any. Each one builds on the last.
Start With Clean, Towel-Dried Hair
Wash your hair with shampoo and conditioner suited to your hair type. After rinsing, gently squeeze out excess water with a towel. But don’t rub, this causes frizz and breakage.
Your hair should be damp, not dripping wet or completely dry. If water is still running down your back, towel dry more. If your hair feels almost dry, spritz it lightly with water.
Apply Heat Protectant and Products
Spray heat protectant evenly through all your hair, from roots to ends. Then apply volumizing mousse at your roots and work it through with your fingers.
Let your hair air dry for 5–10 minutes if you have time. Starting on slightly drier hair speeds up the process and reduces heat exposure.
Section Your Hair
Divide your hair into four sections: left side, right side, top, and back. Clip three sections up and out of the way while you work on the fourth.
Work in small subsections within each main section. Each subsection should be no wider than your round brush and no thicker than one inch. Smaller sections dry faster and give you more control.
The Rough Dry (Optional for Most Hair Types)
If you have straight or slightly wavy hair, rough dry your hair to 80% dry before using the round brush. Use your hands to lift and stretch your hair while pointing the dryer downward. This cuts your round brush time significantly.
Skip this step if you have fine, wavy, or curly hair. These textures need the control of the round brush from the start, or they’ll get frizzy.
The Roll and Follow Technique
This is the core of round brush blowouts. Master this technique and everything else falls into place.
Place your round brush under a small section of hair at the roots. Pull the brush upward and away from your scalp to create lift. As you pull, roll the brush to wrap the hair around the barrel.
Follow the brush with your blow dryer, keeping the nozzle 6 inches away and always pointing downward. The downward airflow smooths the hair cuticle and prevents frizz.
Keep rolling the brush through your hair from roots to ends, following with heat the entire time. Make 2–3 passes over each section before moving on.
The Root Lift Method
For maximum volume at your crown, change your angle. Instead of pulling the brush away from your head horizontally, pull it straight up toward the ceiling while applying heat at the roots.
Hold this position for 3–5 seconds while the heat works, then roll the brush down through the rest of the section.
The Cool Set
Once a section is completely dry, and we mean bone dry, not just dry to the touch, switch to the cool shot button. Keep the hair wrapped around the brush and blast it with cool air for 5–10 seconds.
This step seals the hair cuticle and locks in the shape. Skip this and your blowout will fall flat within hours, no matter how well you executed the rest of the technique.
Finishing Touches
After you’ve blown out all sections, run the round brush through your hair one more time without heat to blend everything together. Then apply a light mist of flexible-hold hairspray.
For extra shine, warm a few drops of lightweight hair oil between your palms and smooth it over your ends. But don’t put it in your roots. This will make your hair look greasy.
Round Brush Technique by Hair Type
Different hair textures need different approaches. Follow the modifications below based on your hair type.
Straight Hair
You have the easiest time with round brush blowouts because your hair cooperates naturally. Rough dry to 80% before using the round brush. Focus on lifting at the roots. Straight hair tends to lie flat without enough volume.
Wavy Hair
Start on damp hair without rough drying. Use more tension than you think you need. Really pull that brush through firmly. Wavy hair wants to spring back to its natural texture, so you need to convince it otherwise with steady tension and multiple passes over each section.
Curly and Coily Hair
Begin on wet (not just damp) hair for maximum smoothing power. You’ll need significant tension at the roots to straighten your texture. Work in smaller sections than straight-haired people would use.
Consider using a paddle brush first to stretch your hair before switching to the round brush for styling.
Fine Hair
Skip the rough dry phase entirely. Fine hair gets frizzy fast when you use your hands. Go straight to the round brush technique on damp hair. Use a medium heat setting (not high) to avoid damage. Fine hair shows heat damage faster than thick hair.
Work in very small sections. What looks like a small section on thick hair is too much for fine hair.
Why Your Blowout Isn’t Working (And How to Fix It)
Even with perfect technique, problems happen. Here’s how to troubleshoot the most common issues.
Problem: Hair keeps tangling in the brush
Your sections are too large, you’re using too small a brush, or you need to slow down. Try a larger barrel brush and take smaller sections of hair. If your brush has damaged bristles, replace it.
Problem: Roots go flat within an hour
You’re not using enough tension at the roots, or you skipped the volumizing product. Pull harder when you lift at the roots, and make sure you’re directing heat right at the base for 3–5 seconds. Add root lifter or volumizing spray before you start next time.
Problem: Ends flip the wrong direction
The direction you rotate the brush determines which way your ends curl. If your ends flip out when you want them in, rotate the brush in the opposite direction while drying. Hold the cool shot longer on the ends to set the curl.
Problem: Takes forever and arms hurt
Sit in a chair while blow drying instead of standing. This conserves energy significantly. Make sure you rough dry to 80% before using the round brush (unless you have fine or curly hair). Use a lighter blow dryer. If you’ve done all this and it still takes over 45 minutes, your sections might be too small.
Problem: Hair looks frizzy and uneven
You’re not drying each section completely before moving on, or you’re directing airflow upward instead of downward. Touch each section after it cools. If it feels even slightly damp, keep drying. Always point your dryer nozzle down the hair shaft, never up.
When to Seek Professional Help
If you’ve tried these fixes and still struggle after 3–4 attempts, consider booking a hands-on lesson at Artists & Architects Salon in Ridgewood. Sometimes seeing the technique in person and having a stylist guide your hands makes all the difference. Our stylists can also assess your specific hair type and recommend the right tools for your texture.
How Long Does This Actually Take?
Set realistic expectations so you don’t get discouraged.
First attempt: 45–75 minutes (and that’s completely normal)
After 3–4 attempts: 30–50 minutes
Once you’ve mastered it: 25–40 minutes
Time by hair length:
- Short hair: 20–30 minutes
- Shoulder-length hair: 30–40 minutes
- Long hair: 40–60 minutes
Remember, salon blowouts take 30–45 minutes even with professional training and practice. Don’t beat yourself up if your first few attempts take longer. The speed comes with repetition.
Best Products for Round Brush Blowouts
You already know the categories you need (heat protectant, volumizer, serum, hairspray). Here are the specific formulas that work best for round brush techniques.
Heat protectant: Look for products that protect up to 450 degrees and contain keratin or other proteins. Your hair is mainly composed of protein, so keratin-based products strengthen strands while protecting them.
Volumizing mousse: Choose a lightweight formula that won’t make your hair stiff or crunchy. Apply to roots while hair is still damp for maximum lift.
Smoothing serum: Pick a plant-based, lightweight oil like argan or jojoba. Heavy serums weigh hair down and defeat the purpose of the volumizing work you just did.
Flexible-hold hairspray: Your hairspray should hold the style without making it stiff or sticky. Look for formulas labeled “brushable hold” or “flexible hold.”
Dry shampoo: This extends your blowout’s life by absorbing oil at the roots on days two and three. Spray at your roots, wait 2 minutes, then massage it in with your fingertips.
FAQ
What size round brush should I use for a blowout?
Choose your brush size based on your hair length and the results you want. Small brushes (1–1.5 inches) work best for short hair or creating tight curls. Medium brushes (2–2.5 inches) suit shoulder to mid-back length hair. Large brushes (3+ inches) are ideal for long hair or maximum volume. If you can only buy one brush, get a large one since it’s easiest for beginners to control.
How long does a round brush blowout last?
A round brush blowout typically lasts 3–5 days, depending on your hair type and how well you maintain it. Fine hair might lose volume faster, while thicker hair holds the shape longer. Using dry shampoo on day two or three helps extend the style.
Can I use a round brush if I have short hair?
Yes, short hair works great with round brushes. Just make sure to use a smaller barrel (1–1.5 inches). The smaller brush gives you control over the short sections and creates the right amount of curl for your length.
Will a round brush blowout damage my hair?
Not if you do it correctly. Always use heat protectant, don’t use the highest heat setting the entire time, and make sure your hair is completely dry before applying the cool shot. Limit round brush blowouts to 2–3 times per week maximum to give your hair recovery time.
What’s the difference between a round brush blowout and a regular blow dry?
A regular blow dry just gets your hair dry. A round brush blowout shapes your hair while drying it, creating volume at the roots and curl or smoothness at the ends. The round brush does the work that curling irons or flat irons would normally do.
Do I need different brush sizes for different parts of my head?
Not necessarily, but many people prefer using a larger brush on the crown for volume and a medium brush around the face for more defined shape. If you only buy one brush, get a large one.
How do I keep my blowout from getting flat while I sleep?
Loosely gather your hair in a high ponytail (the “pineapple” method) with a silk scrunchie, or sleep on a silk pillowcase. Both reduce friction that flattens your style. Never sleep with your hair down on a cotton pillowcase if you want your blowout to last.
