Cleaning the diffusers
The diffusers are magnetically attached to the sides of the straightener’s arms. We recommend these are kept clean, free from debris and hair product residue. This will keep them functioning effectively.
Remove the diffusers by sliding them off the arms of your machine.

Soak the diffusers in warm soapy water for 30 minutes.
Rinse under running water, cleaning off any stubborn debris with a cloth, brush or fingers.
Leave to fully dry.
Refit the diffusers onto the machine.

Styling tips
For advice on how to best use your Dyson Hairstrait™ please follow the steps in the video.
Find the text version of the step-by-step guide instead, under "Is there anything else we can help you with?”
Straightening from dry
Unlock the arms.

Set your straightener to Dry mode.

If using idle mode, your straightener's airflow will reduce between passes, then increase as soon as you close the arms.
Idle mode can be toggled on and off in the the settings menu.
In Dry mode, your straightener has a choice of temperatures and an additional Boost when needed.

Use Cold mode to set your style. Hold your straightener with the arms shut and direct the airflow down the hair section to smooth and set.

Straightening from wet
Your straightener is designed to be used with towel-dried hair, not dripping wet hair. Once towel-dried, detangle your hair with a brush or comb.
For the optimum experience, use maximum airflow and a higher temperature, and direct the airflow towards your roots.
Before starting to straighten your hair, dry your roots with the arms of your straightener closed. You can use your straightener with the arms locked or just hold them closed.

Unlock the arms.

Set your straightener to Wet mode.

If using idle mode, your straightener's airflow will reduce between passes, then increase as soon as you close the arms.
Idle mode can be toggled on and off in the the settings menu.
Your straightener will give you a choice of temperatures that you can change according to your hair type and styling preference. Use lower temperatures for finer hair, and higher temperatures for thicker hair.
Hold your straightener so that the airflow is directed downwards and start to pass sections of hair through the arms. Repeat until each section is dry. Change the airflow and temperature settings as required.

Use Cold mode to set your style. Hold your straightener with the arms shut and direct the airflow down the hair section to smooth and set.

Auto pause
The Dyson Airstrait™ will auto pause when left for three seconds with the arms open. This is an energy saving feature. Pick up the machine, close the arms or press a button (except the power button) to wake it up.

You can prevent your straightener from Auto pausing.
Press and hold the Mode button on your straightener until the settings menu appears.
Use the Mode button to scroll through the menu options.
Press the Cold mode button to select and press again to toggle between on and off.

Idle mode may cause lights to dim
If using incandescent or halogen bulbs, high power appliances such as your Dyson Airstrait™ straightener, may cause lights in your home to flicker or dim. They draw more electricity, which temporarily takes power away from other appliances on the same circuit.
If light dimming occurs when using your straightener, try plugging in to a different outlet and circuit. A professional can help to identify suitable outlets.
Enabling or disabling Idle mode
You can enable or disable Idle mode in the settings menu.
Press and hold the Mode select button until the settings menu appears. Press the Mode select button again to enter.

Press the the cold Mode button to select and press again to toggle between on and off.
When finished, press and hold the Mode select button for three seconds to exit the settings menu.
