Rank #4 in Best Hair Dryer 2026: 10 Ranked by Spec Sheet, Not Slogans
Dyson Supersonic Hair Dryer
Price and rating as shown on Amazon when we collected them. Both change.
The Dyson Supersonic sits fourth in this guide and is the most expensive hair dryer in it at £299.00. The same listing carries a 4.7 out of 5 rating from 147 ratings. Its finding is unlike the rest of the ranking: there is no weight figure anywhere in its specification, so the gap between a marketing weight and a spec-sheet weight that runs through the other three entries simply cannot be checked here. What the page does give is 1600 watts, a maximum temperature of 100 degrees Celsius, and a bullet claiming it "Protects hair's natural shine. No heat damage."
Two things on the listing do not add up. The page reports 147 ratings, but the star breakdown underneath — 82 at five stars, 15 at four, 2 at three and 1 at one — totals 100. And the specification lists "3" speeds and, separately, "4" settings, without saying which of the two covers heat. Everything below comes from the Amazon product listing, price and figures included, and not from any testing we have carried out.
How those 147 ratings break down
An average hides its own shape. This is the spread behind the 4.7 stars.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Good cord length. Not too heavy. Good power. My hair length is past my bra line and it can dry my hair in about 5-7mins continuous use on max air power and lowest heat function. Im just using the round attachment because for drying only. Never tried the frizz control. Been using it for 8months. Lovely product.”
Verified purchase“Brilliant for not blasting your hair with extreme heat very well made not too heavy the nozzle is great for drying in quick time would highly recommend”
