Frequently asked questions

Can I use my Dyson Airstrait™ straightener on dry hair?

Yes, you can use the Dyson Airstrait™ to touch-up and refresh your style from dry. To use on dry hair, select Dry mode and choose between the pre-set temperatures, depending on your hair type and intended style.

Will my straightener turn off if I accidentally leave it on?

Your Dyson Airstrait™ will enter auto-standby after five minutes of inactivity when the arms are left open, or three minutes if the arms are locked. The LCD screen will turn off and you'll need to press the power button to turn the machine back on.

Can I use my Dyson Airstrait™ straightener when travelling to countries with different electrical voltage?

Your straightener has been precisely engineered for styling at the voltage of the country in which it was purchased. This allows it to run at optimum performance. As voltage varies from country to country, please follow the guidance on usage in the guarantee section of your user manual.

How often do I need to clean the filter?

To maintain optimum performance, your Dyson Airstrait™ straightener needs regular care and maintenance. We recommend cleaning the filter once a month. Debris should be wiped from the outer filter cage and from the inner filter mesh using a soft, dry cloth.

Do I need to clean my machine?

Yes, we recommend regular cleaning of your machine for optimum performance. You can find detailed instructions on how to clean and deep-clean your filter, tension bars and diffusers in your online user guide, on our Support pages or on your MyDyson™ app.

Can you use the Dyson Airstrait™ straightener on wet hair?

Yes. The Dyson Airstrait™ straightener is designed around wet-to-dry styling, allowing you to dry and straighten hair as part of the same styling routine.

Does the Dyson Airstrait™ straightener use hot plates?

No. The Dyson Airstrait™ straightener uses precisely heated air rather than hot plates. Air is projected evenly through the hair as you style, so there is no physical contact from heated plates.

What is the difference between the Dyson Airstrait™ straightener and a Dyson Airwrap™ multi-styler and dryer?

The Dyson Airstrait™ straightener is designed to dry and create naturally straight styles from wet using air, without hot plates. A Dyson Airwrap™ multi-styler and dryer offers broader styling versatility, with attachments for curls, waves, smoothing and volume as well as drying. Choose Airstrait™ when straightening is the priority, or Airwrap™ when you regularly switch between several styles.

  • 1 vs. air drying when used in wet to dry mode.
  • 2 When used in wet to dry mode vs. hot plate straighteners which operate with extreme heat.
  • 3 vs. separate drying and straightening steps.
