A good blow dry is the foundation to a good hair day. The fanciest hair straightener or curling wand in the world won't do you much good if your hair was singed with a crappy blow dryer beforehand. That's that on that.
It's common knowledge that pressing hair onto a sizzling hot flat iron or curling iron isn't great for it. We're quick to blame those tools for split ends and frizz, but less often, we consider that part of the problem may be the way the hair was dried in the first place. If your lifelong dream has been to give yourself the same glossy blowout that you get at the salon, your skills might not be totally to blame — your stylist's professional blow dryer is a lot better than your drugstore one.
Are expensive blow dryers worth it?
Do you care about your hair looking great and being healthy? Then yes.
"Does it actually matter? Hot air is hot air, right?" Well, it's not that black and white. Beauty YouTube is a sucker for comparisons between high-end and budget-friendly dryers, but what's not being shown in that single demo is the effect of frying your hair with a cheap dryer on a daily basis.
However, that damage will make itself known as your hair becomes increasingly resistant to a silky blowout and when those flyaways refuse to lay flat.
Hair taking forever to blow dry is the number one red flag in the world of hair dryers. Most low-quality ones don't have adjustable heat settings, and if they do, both are too hot and are literally burning your hair dry. That extreme heat probably doesn't even speed up the process, as their motors usually aren't strong enough to create the velocity or targeted airflow necessary for a thorough job.
Speaking of cheap motors, affordable hair dryers don't really save money in the long run when they need to be replaced so often. Budget-friendly dryers aren't meant to withstand all-day use like a professional one, but this also means they have a tendency to blow out (no pun intended) after a few months of daily use. They're also super loud, have short cords that are prone to breaking when tugged (like a non-Apple iPhone charger), and have filters that are hard to clean. It takes guts to drop the cash on a professional model, but it'll last for years.

How do you blow dry your own hair professionally?
Pro tip: Dry before you dry.
If you can wring your hair out and see water droplets falling, it's too wet to blow dry. Moisture causes the keratin in hair to create weak hydrogen bonds that stretch when combed or blown around. The protective cuticles around the keratin stretch, too, and they don't bounce back to normal after drying. Instead, wet cuticles can crack or lift, making the hair inside more susceptible to damage. It's the same reason why you shouldn't go outside with wet hair in winter(opens in a new tab). Air dry or towel dry as much as possible.
Direction of airflow also matters. We asked stylists on Instagram, read tips from celebrity stylists, and watched review vlogs, and one unanimously-backed technique stood out: Keep that dryer pointed down, honey.
Amy Loveland(opens in a new tab), a stylist at Platinum Salon in West Chester, PA, finds that clients aren't getting the smoothness they want at home because they're blowing in the wrong direction.
"Instead of properly closing the cuticle, they blow the hair so that the cuticle stands up and their hair becomes fluffy rather than that fresh, blown-out look," she told us. "Blowing hair in the opposite direction while still keeping the airstream pointed down the hair shaft will give you the most volume while keeping smoothness."
The goal is to create a silky bounce in a single pass (AKA using as little heat as possible). Zooming through your whole head with the dryer pointed all over is just asking for a puffy 'do — and not in the wind-blown, voluminous way that everyone wants. Blowing downward is also key in making those static-y ends lay flat.
Things to look for when shopping for a new hair dryer:
At least three heat settings: You know how hair dryers in hotel rooms have an on/off switch and that's it? That's not what you want here. Precise control of heat lets you customize temperature based on your damage level and the sleekness (or lack thereof) that you're going for. Some even have a "no heat" option for the days where you're not drying to style.
A cool shot button: A dryer needs to be able to switch from hot to icy air with the press of a button. The cold seals those cuticles, which is crucial to achieving a blowout that lasts for days. Celebrity stylist Harry Josh (the creator of our pick for the best quiet hair dryer) proves the importance of a cool shot in this video by Goop(opens in a new tab). Skip to the 3-minute mark to see how a few seconds of cold air can change the way hair holds a curl.
A range of attachments: Sectioning hair and using a nozzle to compress airflow directly onto the brush allows you to concentrate on smoothing one strand at a time. Diffusers are essential (!!!) in styling curly or coarse hair(opens in a new tab). These use small holes to diffuse air around curls to prevent cuticles from getting rough while preserving the natural shape of the ringlet.
A long cord: Professional hair dryers usually have a 9-foot cord while basic hair dryers have a 6-foot cord. Stylists need the freedom to move around a chair, and people at home will appreciate this if their bathroom has inconvenient outlets.
Don't forget that heat protectant, y'all. Jonathan Van Ness(opens in a new tab) suggests Oribe's Foundation Mist(opens in a new tab).
