Dyson Supersonic Nural Review: Is Scalp-Sensing Heat Worth $500?
The Nural backs off its heat as it nears your scalp and pauses itself when set down. It is a real feature, but cheaper high-speed dryers dry hair almost as fast.
Our verdict
Excellent dryer, poor value. The distance sensor and auto-pause genuinely protect your scalp, and daily dryers will use them. Everyone else gets nearly the same drying from a $200 high-speed dryer, so most people should skip the premium.
Best forDaily dryers with a sensitive scalp or fine, heat-prone hair
What we liked
- Time of Flight sensor lowers heat as the nozzle nears hair
- Auto-pause cuts heat when the dryer is set down
- Four heat settings including a constant 82°F cool shot
- Light for a flagship at 1.49 lb (0.68 kg)
What held it back
- $499.99 is more than double a Shark SpeedStyle bundle
- Drying speed is only slightly ahead of cheaper rivals
- 77 dB is not quiet
- Sensor features matter little if you dry hair rarely
The Supersonic Nural is a very good hair dryer and a hard one to justify. Its scalp-aware heat control is a real feature, and it is the only reason to pay $499.99 instead of roughly $200 for a fast dryer from Shark. If your scalp runs sensitive or you dry your hair every single day, read on. Everyone else can stop here and keep around $300.
What the sensor actually does
Most expensive dryers sell speed. The Nural sells restraint. A Time of Flight sensor in the head measures how far the nozzle sits from your hair, and in Scalp Protect mode it lowers the heat as you move closer, aiming for a steady 55°C at the scalp. A second sensor notices when you put the dryer down or hold it still while sectioning, then cuts the heating element and drops the airflow until you pick it up again.
We read this as a safety margin more than a speed trick. Heat damage builds slowly and you never see it happen, so a dryer that backs off on its own is doing something you would otherwise have to do by habit. That is the honest case for the price, and it is a narrower case than the marketing makes.
Reading the heat settings
The four temperatures are worth a moment, because they show how Dyson thinks about hair. The 212°F setting is for fast drying of thick, coarse hair. The 176°F setting is the everyday default, 140°F is the gentle option for fine or damaged lengths, and the 82°F cool shot sets a style once the shape is right. Fine hair that frizzes at high heat is the case where we would expect the lower settings and the scalp mode to matter most.
