The no-fluff verdict

This is a dryer that feels balanced in your hand, gets you out the door faster, and leaves hair smoother and shinier without cooking it. Its smart heat control and easy snap-on attachments are its best tricks. The catch is the steep price, plus a heavy cord and controls that take getting used to. It suits people who blow-dry often, especially those with thick, curly, or heat-sensitive hair, who are happy to splurge.

This verdict draws on 21 independent sources: 16 expert tests, 61,144 ratings and reports from retailers, owner communities and video reviews, and official safety records, analyzed and cross-checked into one verdict, so you don't have to.

Questions people actually ask

Is drying your hair with the Dyson Supersonic bad for it?

No, it's one of the gentler ways to blow-dry. It checks the air temperature constantly and leans on strong airflow instead of extreme heat, so your hair takes less of a beating.

Based on: Most of 16 expert sources cite its temperature sensor and lower heat.

Is a blow dryer like the Supersonic bad for color-treated or damage-prone hair?

Not in the usual way. It keeps the heat in check and pairs with a cool shot, so color-treated and fragile hair holds up well, though high heat used too long can still dry hair out.

Based on: One hands-on tester saw no new split ends after 24 blow-dries.

Is the Dyson Supersonic hair dryer bad for your scalp?

No, it's built to go easy on your scalp. The newer version senses when it's close to your head and turns the heat down on its own.

Based on: Several hands-on testers praise Scalp Protect; one never burned their scalp.

How do you use the diffuser on the Dyson Supersonic?

Snap it on magnetically and let it spread soft air through your curls. The newer diffuser has a dome mode for gentle drying and a prong mode for working through curls at the root.

Based on: Hands-on testers describe its magnetic diffuser and dome and prong modes.

What if my Dyson Supersonic stops working?

It happens, but not often. A small share of people run into a dead unit or cord trouble, and some find getting help from the company frustrating.

Based on: Our research found 6% of owner comments report failures, 4% poor support.

Usually $400–$500 in the US. Prices move with sales, so check the current price.

Based on: Prices quoted in expert reviews and at Amazon.com.

Mostly replacement parts and supplies

  • Extra attachments such as other-sized concentrators and smoothers are sold separately (prices not stated)
