Is the Dyson SuperSonic Hair Dryer Worth The Money?

As a life long beauty connoisseur, I wanted a Dyson SuperSonic hair dryer from the moment that it launched. I watched countless YouTube videos, read reviews and lusted after it for months. Is it worth the money? Does it really make a difference? What is so special about it? I agonized over whether or not it was worth the hefty price tag—because at $400, it’s not a cheap piece of equipment. 

After using it for over a year, I now feel fully qualified to talk about whether or not the Dyson Supersonic hair dryer is worth the money. Read on for my thoughts.


Dyson is known for the advanced technology they use in their products and, true to form, the Dyson Supersonic hair dryer is not your normal, run-of-the-mill hair dryer. According to Dyson, it’s engineered to protect hair from extreme heat damage with intelligent heat control, uses a special v9 digital motor for fastest drying and controlled styling to help increase smoothness by 75%, increase shine by up to 132% and decrease frizz and flyaways by up to 61%.

In layman’s terms, that means that the Dyson Supersonic hair dryer has an ultra powerful airflow that dries your hair faster than usual while also preventing heat damage.


When it came to reimaging the hair dryer, Dyson didn’t f*ck around.The brand invested $71 million dollars, hired dozens of new employees (more than 100 engineers worked on this!), and brought on some of the world’s top hairstylists (including Jen Atkin) to help create a blow-dryer that was lighter, quieter, and more efficient than anything on the market.

They didn’t stop there. Tom Crawford, Head of Product Development at Dyson, actually required that all the engineers working on the hair dryer take hair styling classes at a community college because he wanted them to truly understand the science of hair and what goes into styling it.


One of the first things that you’ll notice about the hair dryer is that it looks nothing like the blow dryer you’re currently using—because there’s a hole in the middle of it. The nozzle has been replaced by what looks like a large cylinder, which is the brand’s patented Air Multiplier technology, (i.e. the bladeless fans they put in practically every device they make). 

According to the brand, the dryer works by taking a little air from the bottom and drawing into the motor at the top of the handle, while also pulling a little extra air through the middle and the sides of the cylinder. All that air is then multiplied threefold as it’s pushed out through the center of the ring toward your hair. This results in less air flowing through the product, which means the motor can be smaller (i.e., the dryer can be lighter!), and there is more air flowing out. The silver lining: you’ll never have to worry about your hair getting sucked into the back of the dryer again.


The device uses what’s called Air Multiplier technology to create a high-pressure, high-velocity stream of air. What helps to make styling more precise is the handful of magnetic attachments included with the Supersonic: It comes with a smoothing nozzle and styling concentrator, which both help focus the airflow, as well as a diffuser for defining curls and waves.

Another advancement: in addition to the four heat settings (and three airflow settings), inside the hair dryer is a tiny little thermometer that measures the air temperature 20 times per second to make sure that the air never gets too hot. How cool is that? This ensures that the integrity of your hair remains intact and you never use too much heat on it—it also ensures t that the device itself never gets too hot (so you won’t burn yourself if/when you change attachments). 


The dryer retails for $399, which is insanely expensive. However, that includes things other than just the hair dryer. Regardless of where you purchase the device, it comes with four magnetic attachments so you can adjust quickly and easily. Right now, it also comes with a silicone mat to rest the dryer on, but when I bought mine it came with a nice metal stand. Either way, you’re getting an entire hair drying/styling experience and all the accoutrements, not just the dryer itself (in case you’re looking for a way to justify the expense LOL).

Also, I purchased mine (and the one I got for my mom) from Ulta’s website. I used my Ultamate Rewards Points to buy it (I’m Diamond so I accrue points quickly—and I used the points I got from purchasing mine to buy my moms). I also used Rakuten on the purchase, which means I 6% cash back on it. Win/win!


This hair dryer might look drastically different than what you’re used to, but it operates exactly the same. On days where I just want to dry my hair and call it a day, I rough dry it or dry it with my Yves Durif vented brush. On days where I plan on styling my hair after drying it, I section it off with my favorite clips, and dry it with a round brush.


Obviously, how much money someone is willing to spend on something is very personal and completely subjective. For me, the dryer was 100% worth it. I wash and style my hair every single day (or I did before COVID). Not only does this dryer dramatically reduce the amount of time that I have to spend on doing my hair, it also reduces the damage that I inflict upon my poor hair by doing it every day. 

I have long hair that takes forever to dry and I’m not exaggerating when I say that this has cut the time I spend blow drying my hair in half. If you have short hair, or hair that doesn’t take long to dry, and that’s your most important consideration when debating this purchase, this might not be the best investment. However, the deciding factor for me, and the reason that I would repurchase this immediately if mine died tomorrow, is because it helps protect the integrity of my hair and keeps it healthy.

Other things that I love about the dryer: it’s insanely light weight. I love that Dyson was somehow able to make a dryer that is way lighter than the Conair dinosaur that I was previously using and also pumps out way more air AND makes next to no noise. I mean, how do they do it? Amazing.


If you’re looking for the Spark Notes of this review, here are my favorite things about the machine: It’s light. It’s quiet. It reduces drying time dramatically. It maintains the integrity of your hair. 

Do you have a Dyson SuperSonic? If so, let me know whether or not you agree with my opinion that it’s worth the investment!
