Shop the TNS SuperSilk: $349 60-day money-back · free AU shippingThe Dyson Airstrait ($749 RRP) and the TNS SuperSilk ($349) share the same core technology: air-only wet-to-dry straightening with a high-speed BLDC motor, glass-bead temperature sensors checking airflow about 30 times per second, and the same gentle 80-140 degree range. No hot plates on wet hair, no boiled moisture. The SuperSilk delivers that technology for $400 less at RRP, with a 60-day money-back guarantee to prove it.
Why this comparison exists
Air-only straightening is the biggest step forward in hair care in years, and Dyson deserves credit for mainstreaming it. But the physics isn't exclusive: controlled airflow, low heat, precise sensors. This page compares the two honestly, spec by spec, so you can decide whether the badge is worth $400.

Frequently asked questions
Is the TNS SuperSilk as good as the Dyson Airstrait?
The core technology is nearly identical: air-only heating, BLDC motors, glass-bead thermistors and the same gentle temperature range. The SuperSilk costs $400 less at RRP and adds a 60-day money-back trial.
Does wet-to-dry straightening damage hair?
Air-only wet-to-dry straighteners cause far less damage than hot-plate tools: controlled 80-140 degree airflow resets the hair's hydrogen bonds while drying, instead of boiling moisture inside the shaft at 185-230 degrees.
Can I use the SuperSilk on hair extensions?
Yes. No direct plate contact and a range starting at 80 degrees make it suitable for tape-ins, nano-rings and keratin-bonded extensions.
What if I don't like it?
There's a 60-day money-back guarantee and a 2-year warranty, with free AU shipping.
