Curly hair is a full-time job. Honestly, anyone who tells you otherwise probably has straight hair or a very expensive stylist on speed dial. For the rest of us, the "wash day" struggle involves a mountain of products and a drying process that feels like it takes three business days. When the Shark FlexStyle first hit the scene, everyone naturally compared it to the Dyson Airwrap. But for the curly community, the conversation shifted fast. Why? Because of the diffuser. Using the Shark FlexStyle with diffuser isn't just about drying your hair; it's about whether or not you're going to look like a frizz-ball by noon.
It’s a weirdly shaped tool. It’s a wand that bends into a 90-degree angle, transforming from a sleek dryer into a powerful styling base. Most people get lured in by the curling barrels, but if you have texture, that diffuser attachment is the real MVP.

The physics of the Shark FlexStyle with diffuser
Most diffusers just sort of move air around. This one is different. The Shark attachment features retractable prongs. This sounds like a minor gimmick, but it’s actually a massive deal for different hair lengths. If you have short or medium hair, you leave the prongs retracted. This lets the air flow over the surface of the curls without disturbing the pattern too much. If you have thick, long hair, you extend those prongs. They get right into the roots, drying the scalp area which usually stays damp for hours.
I've noticed that the air distribution is surprisingly even. On a lot of cheap dryers, you get a "hot spot" in the middle of the bowl that fries your ends while the edges stay cold. Shark uses a perforated plate that seems to baffle the air more effectively. It’s not just blowing; it's surrounding.
People always ask about heat damage. The FlexStyle measures temperature 1,000 times per second. That’s the official stat from SharkNinja. In practice, this means you don’t get that sudden "scorched scalp" feeling when you’ve been holding the dryer in one place for too long. It stays consistent. That consistency is what keeps the hair cuticle flat. When the cuticle stays flat, you get shine. When it blasts open from inconsistent heat, you get the dreaded frizz.
Real talk on the "Dyson Killer" label
Is it a Dyson killer? Kinda. It's half the price, which is the elephant in the room. But let's look at the diffuser specifically. The Dyson diffuser is iconic, sure. But Shark did something clever by making theirs deeper. A deeper bowl means you can "plop" more hair into it at once.
If you're using the Shark FlexStyle with diffuser on high-porosity hair, you know the struggle of moisture loss. You need speed, but you can't have high heat. The Shark's airflow is incredibly high-velocity. You can actually use a lower heat setting and still finish your hair in twenty minutes because the air pressure is doing the heavy lifting, not the temperature.
I’ve seen some reviews claim the "Cool Shot" button is hard to hold. It is. It’s a bit of a thumb workout. But that cold air is essential for "locking" the curl once it’s dry. If you skip the cool shot, your curls will likely drop by the time you finish your coffee. It’s a trade-off. A slightly sore thumb for curls that last three days? I'll take it.
How to actually use it without ruining your pattern
Don't just mash the dryer into your head. That’s mistake number one.
- Start by hovering. Keep the Shark FlexStyle with diffuser about four inches away from your head. This "sets" the gel cast or mousse you applied. If you touch the hair while it's still soaking wet, you break the clumps.
- Once a "crust" has formed (we call it a cast), then you start the scrunching motion.
- Move the prongs in and out based on where you're drying. Use the extended prongs for the crown of your head to get volume. Use the retracted setting for the ends.
One thing most people overlook is the "hinge" mechanism. Since the FlexStyle bends, you aren't holding your arm at a weird, tiring angle above your head. You can keep your elbow tucked in and just rotate the nozzle. It’s significantly more ergonomic than a traditional hair dryer with a bulky diffuser attached to the end of a long barrel.
The weight and build quality
It’s light. Like, surprisingly light. 1.5 lbs light. If you’ve ever spent 40 minutes diffusing with an old-school Parlux or a heavy ionic dryer, you know the shoulder fatigue. The Shark feels more like a styling tool than a piece of industrial machinery.
However, it is loud. It’s got a high-pitched whine to it. It’s the sound of a high-speed digital motor, which is common in these types of tools, but if you’re sensitive to noise, it’s something to keep in mind. It’s not "jet engine" loud, but it’s definitely not a whisper.
Dealing with the frizz factor
Frizz is just a curl waiting for a friend. Or, more accurately, frizz is a curl that's been agitated by wind. The Shark FlexStyle with diffuser works best when you keep the airflow on the medium setting. The "High" airflow setting is powerful—maybe too powerful for fine curls. It can blow the curls apart, causing them to string out.
I recommend the "Low" or "Medium" air setting for the first 80% of the dry. Only switch to "High" at the very end if you’re trying to get that last bit of moisture out of your roots.
What the internet gets wrong about the Shark
You see these "perfect" results on TikTok. Usually, those creators have a very specific hair type or they've spent two hours on styling. For the average person, the Shark isn't a magic wand that fixes a bad haircut or a lack of protein in your hair.
It’s a delivery system. If your hair is mushy because you used too much conditioner, the diffuser can't save you. If your hair is brittle, the heat (even regulated) will show that. The Shark FlexStyle works best when paired with a solid leave-in and a high-hold gel.
Also, the "auto-wrap" curlers that come in the bundle? They don't work well on soaking wet curly hair. You have to dry your hair with the diffuser first, maybe to about 90%, and then use the barrels if you want to polish specific face-framing pieces. Trying to use the curling barrels on wet, curly hair usually results in a tangled mess. Use the tools for what they were meant for. The diffuser is for your natural texture; the barrels are for manipulation.
Maintenance and Longevity
Clean your filter. I cannot stress this enough. There’s a small ring at the bottom of the handle. It collects lint, hairspray residue, and dust. If that filter gets clogged, the motor has to work harder, the air gets hotter, and eventually, the thermal sensor will trip and shut the whole thing down.

Take a soft toothbrush and clean that filter once a week. It takes thirty seconds. Most people who complain about their Shark "dying" after six months simply never cleaned the intake. It’s a high-performance machine; treat it like one.
Practical Next Steps for Your Best Curls
If you've just picked up the Shark FlexStyle with diffuser, or you're thinking about it, don't expect perfection on day one. Every hair dryer has a learning curve.
- Check your attachments: Ensure the diffuser is clicked in fully. You should hear a distinct snap. If it's loose, the airflow won't be pressurized correctly.
- Test the prong settings: Spend one wash day with the prongs "in" and the next with them "out." See which one gives you better root volume versus curl definition.
- The 80% Rule: Diffuse until you are 80% dry, then let the rest air dry. This often results in less frizz than forcing it to 100% with mechanical heat.
- Keep the filter clear: Set a reminder on your phone to wipe the bottom intake every Sunday.
- Use the Cool Shot: Spend at least 30 seconds at the very end of your routine blasting your hair with the cold setting to seal the cuticle and add shine.
The Shark FlexStyle is a formidable tool, especially for the price point. It bridges the gap between professional salon equipment and the clunky dryers of the past. If you prioritize hair health and want to embrace your natural curls without spending an hour in the bathroom, focusing on the diffuser attachment is the smartest way to use this system. It’s about working with your hair’s natural physics, not against them.
