Dyson Supersonic™ Hair Dryer Straight+Wavy – Fast Drying Without Extreme Heat – Intelligent Temperature Control – Includes 3 attachments

The Supersonic Straight+Wavy sits between the Origin (cheapest Dyson) and the Nural (smartest Dyson). Three attachments, V9 motor, intelligent heat control. 4.8 stars from 100 reviews, 100 bought per month. Designed for straight and wavy hair types.

Where it fits in the Dyson range

Origin: basic motor + minimal attachments. Straight+Wavy: same motor + 3 attachments for smooth styling. Nural: same motor + 5 intelligent attachments + sensor network. The price steps up with each tier.

If you have straight or wavy hair and don't need a diffuser, the Straight+Wavy is arguably the sweet spot. You get proper attachments without paying for the Nural's AI features, which some people find unnecessary.

No diffuser

Three attachments, none of which is a diffuser. This is explicitly for straight and wavy hair. If you have curly hair, this isn't the right Dyson. The Nural Straight+Wavy model doesn't include one either. For curly hair, our best hair dryer for curly hair roundup has options with diffusers from other brands.

Same V9 motor

110,000 rpm, Air Multiplier technology. Fast drying, lightweight, no extreme heat. Intelligent heat control measures temperature 40 times per second and adjusts to prevent damage. This is consistent across all Dyson Supersonic models. Our what is ionic hair dryer article explains how Dyson's approach differs from ionic tech.

4.8 stars

Highest-rated dryer in our database. 100 reviews is still a small sample, but Dyson products tend to hold their ratings as review counts grow. The people buying this know what they're getting and they're happy with it.

Worth it over the Origin?

If you style your hair rather than just drying it, yes. The attachments make a difference for smooth blowouts on straight and wavy hair. If you just point and dry, the Origin saves money for the same core performance.
