The Dyson Supersonic has generated significant conversation as a premium hair styling tool, with people debating its value, performance, and reliability compared to more affordable alternatives.

---

The Not-so-good

• Reliability issues: “Ugh paid an arm and a leg for one of these only for it to just die one day and never turn back on, 2 months past warranty. Dyson was not sympathetic about it.” (44 upvotes)
• Poor performance for certain hair types: “This shit doesn’t work for stubborn Indian hair” (16 upvotes)
• Not effective in humid environments: “It is a waste of money if you live in a humid place and have curly or wavy hair. Got it on EMI and it was a stupid decision.” (45 upvotes)
• Questionable ergonomics: “It was clearly designed by someone who doesn’t use a hairdryer because the ergonomics for the cold-shot button are just awful.” (24 upvotes)

The Good

• Reduced drying time: “It cut my drying time in half and using the most narrowed nozzle that comes with it, I get a silky smooth blow out.” (17 upvotes)
• Longer-lasting styles: “I’m not sure how, but my style lasts SO much longer with the Dyson. I would need to do a curl refresh at like day 3, but with the Dyson, I don’t need to refresh until 5 or 6.” (8 upvotes)
• Ergonomic design: “I love the ergonomics of it so my wrist doesn’t actually get tired/leave the dryer feeling heavy.” (17 upvotes)
• Reduced heat damage: “It gets really freaking hot but has a great diffuser attachment which evenly spreads that heat and uses sensors to modulate the output to decrease damage.” (13 upvotes)
• Frizz control: “I have curly hair and it also helps control frizz” (27 upvotes)

Worth it?

• Worth it for frequent users: “I blow dry my hair almost every single day, so the price per cost more than makes it worth it.” (6 upvotes)
• Overpriced for marginal benefits: “Personally, the Dyson better be damn well magical for that price. I don’t think it’s worth any marginal gains…” (6 upvotes)
• Justified investment for some: “If it broke today I’d go buy it for full price tomorrow. I have fine but very thick, frizzy/wavy/curly hair that I straighten weekly & takes hours to air dry properly so this cuts down immensely on my drying time and smoothens my hair.” (9 upvotes)
• Disappointing value for certain hair types: “It is a waste of money if you live in a humid place and have curly or wavy hair.” (45 upvotes)

Tips and tricks

• Use high heat for maximum efficiency: “If you’re not taking advantage of the heat output, you’re not going to reduce your drying time.” (12 upvotes)
• Hover diffusing technique: “You can hover diffuse (let’s say about 7-10″ from your head) on high without approaching [damage-causing temperatures].” (7 upvotes)

The verdict?

The consensus suggests that while the Dyson Supersonic can be a worthwhile investment for those who style their hair frequently and have the right hair type, it may not deliver the expected results for all users, particularly those with very curly, coarse hair or those living in humid environments.
