You know that feeling when you leave the salon and your hair feels like silk, but then you try to recreate it at home and end up with a tangled, frizzy mess? It’s frustrating. Most of us aren't professional stylists with the forearm strength to juggle a heavy ionic dryer in one hand and a ceramic round brush in the other for forty minutes. This is exactly why the Drybar round brush dryer—specifically known as The Double Shot—became a cult favorite. It’s basically a cheat code for anyone who wants volume without the bicep workout.
Honestly, the "blowout brush" market is incredibly crowded now. You’ve got the Revlon One-Step that everyone bought in 2019, the high-end Shark FlexStyle, and the Dyson Airwrap which costs as much as a used car. But Drybar’s version sits in this weirdly perfect middle ground. It’s not a budget tool that’s going to fry your cuticles, but it’s also not a $600 investment that requires a PhD to operate.
People often ask me if these tools actually work on different hair types. The answer is usually "it depends," but with the Double Shot, the physics are pretty straightforward. It uses ionic technology to reduce frizz, which is a fancy way of saying it seals the hair cuticle using negative ions. If you have fine hair, you get lift. If you have thick hair, you get smoothness. It’s rare to find a tool that doesn't discriminate against hair texture.
What Most People Get Wrong About the Drybar Round Brush Dryer
A big mistake I see? People try to use this on soaking wet hair. Don't do that. You’ll be there for an hour, and you'll probably cause heat damage. The Drybar round brush dryer is a finishing tool, not a towel replacement. You want your hair to be about 70% to 80% dry before you even touch this thing. Air dry while you do your makeup, or use a regular blow dryer to blast the roots first.
Another thing—tension matters.
If you just limp-handedly brush through your hair, you’re just drying it. You aren't styling it. To get that "Drybar look," you have to pull the hair taut against the bristles. The tension is what creates the shine. Think of it like ironing a shirt; you can't get the wrinkles out if the fabric is bunched up.
There’s also a misconception that the "Single Shot" and "Double Shot" are just different names for the same thing. They aren't. The Single Shot has a 2.25-inch round barrel, which is meant for shorter hair or creating tighter waves. The Double Shot has a 2.44-inch oval barrel. That oval shape is crucial because it allows for more surface area to touch the hair, which leads to more volume at the root. If you have long hair, go for the Double Shot. If you have a bob or lob, the Single Shot is your best friend.

Why Heat Settings are the Make-or-Break Factor
Let’s talk about the specs because this is where people get into trouble with their hair health. The Double Shot has three settings: Cool, Medium, and High.
Most people crank it to High immediately. Unless you have extremely coarse, thick hair, you probably don't need that. High heat on a tool that stays in direct contact with your hair for several seconds can lead to breakage over time. I usually recommend the Medium setting for almost everyone. It’s plenty hot enough to shape the hair without turning it into straw.
- Cool Shot: This isn't just a gimmick. Use it for the last 10 seconds of each section to "set" the style.
- The Bristles: Drybar uses a mix of nylon and tufted bristles. The nylon ones detangle, while the tufted ones provide the grip needed for shine.
- The Weight: It weighs about 1.2 pounds. That sounds light, but after 15 minutes over your head, you'll feel it. Still, it beats the "dryer in one hand, brush in the other" struggle.
Experts like Alli Webb, the founder of Drybar, have always emphasized that the "secret" isn't just the tool, but the sectioning. If you take a massive chunk of hair and try to dry it all at once, the middle won't get any heat, and the outside will get scorched. Use clips. It feels like an extra step, but it actually saves you time.
The Durability Debate: Is It Worth the Premium?
You can buy a knock-off version of a round brush dryer for $40 at a drugstore. So why spend significantly more on the Drybar version?
Reliability.
The motor in the Drybar round brush dryer is designed to handle consistent airflow without overheating. Cheap motors often start smelling like burnt electronics after six months of use. Also, the vent design on the Drybar model is specifically engineered to prevent hair from getting sucked into the bottom—a terrifying experience that anyone who has used a cheap hair tool knows all too well.

I’ve seen stylists in actual Drybar locations use these tools all day long. While the consumer version isn't exactly the same as the industrial-strength ones they use in-shop, the DNA is there. The ergonomics are better. The cord is professional-length (9 feet!), so you aren't tethered to the wall like a dog on a leash.
Real-World Results for Different Textures
- Fine, Flat Hair: This tool is a miracle for you. Focus on the crown. Pull the brush straight up toward the ceiling as you dry.
- Curly/Coily Hair: You might need a higher heat setting and smaller sections. It won't give you a "silk press" look as well as a flat iron would, but it provides a great "fluffy blowout" aesthetic.
- Frizzy/Processed Hair: Use a heavy-duty heat protectant. The "Prep Rally" spray from Drybar is actually specifically formulated to work with the ions in this brush.
Comparing the Competition
It’s impossible to talk about the Drybar brush without mentioning the Shark FlexStyle or the Dyson Airwrap. Those tools are multi-functional. They curl, they dry, they smooth. However, they are also incredibly complex. Sometimes you just want one tool that does one thing perfectly.
The Drybar brush is that tool.
It doesn't try to be a curling iron. It doesn't try to be a diffuser. It’s a round brush that blows hot air. That simplicity is actually its greatest strength. You don't have to swap out attachments with wet hands or worry about losing a piece of the kit while traveling.
One downside? It’s bulky. If you’re a minimalist traveler, this is going to take up half your carry-on. But for most people, the trade-off of having perfect hair in 15 minutes is worth the luggage space.
Maintenance and Longevity
If you want your Drybar round brush dryer to last more than a year, you have to clean it. This is the part everyone ignores.

Hair, dust, and product buildup will clog the air intake at the bottom. Once that happens, the motor has to work twice as hard, it gets too hot, and eventually, it just dies. Once a week, take a pair of scissors and carefully snip the hair out of the bristles. Then, use a small brush (even an old toothbrush works) to clear the dust from the bottom filter.
It takes two minutes. It adds years to the tool’s life.
How to Get the Most Out of Your Blowout
To truly master this tool, you need to think about the product "sandwich."
Start with a volumizing mousse or a smoothing cream on damp hair. Then, apply a heat protectant—this is non-negotiable. Dry the hair in sections, starting from the bottom and working your way up to the top. When you get to the very front pieces (the "money pieces"), wrap the hair around the brush and roll it away from your face.
Hold it there for a few seconds on the "Cool" setting. When you let it go, you’ll have that effortless, swept-back look that usually costs $50 at the salon.
Finally, finish with a tiny bit of hair oil or a light-hold hairspray. Don't overdo it. The beauty of a blowout is movement. If you douse it in heavy spray, you lose that "bounce" that makes the Drybar round brush dryer worth using in the first place.
Actionable Steps for Your Next Wash Day
- Prep is key: Towel dry your hair thoroughly or use a microfiber wrap to get the excess moisture out. Aim for 75% dry.
- Section properly: Use at least four sections (bottom left, bottom right, top left, top right). If you have very thick hair, do six.
- The 90-degree rule: Always pull the brush out at a 90-degree angle from your head to maximize volume at the roots.
- Clean your tool: Set a monthly reminder to remove hair and dust from the vents to prevent motor burnout.
- Protect the ends: The ends of your hair are the oldest and most fragile. Apply extra heat protectant there and try to avoid running the brush over them more than three times.
The reality is that no tool is magic, but the Drybar Double Shot comes pretty close for the average person who just wants to look put-together without the stress. It’s a reliable, mid-tier luxury that delivers on its promise: salon-quality hair in your own bathroom.
