Let the curls rest in the bowl
Lift a section into the diffuser's bowl and hold it against your head for a moment before moving on. The curls dry in their own shape instead of being frizzed by straight air.
Prongs that grow with your hair
Turn to extend the prongs when your hair is thick or long and you want to reach the roots – shorter prongs are enough for shorter styles.

Product FAQ
Will it fit my Shark FlexStyle?
Shark states it fits FlexStyle HD420, HD430, HD435, HD440 och HD441. FlexStyle attachments share the same click-on fitting, so in our assessment it also fits the FlexStyle HD426, HD446, HD456 and HD476 we sell – that's our conclusion, not Shark's statement. It does not fit SpeedStyle, Glam or other Shark hair dryers.
How do I attach it?
The attachment clicks onto the end of the styler and comes off with the release button. Let it cool for a moment before swapping attachments.
Why are there two colours?
Shark makes the attachment in two colours to match different FlexStyle finishes. It works the same way – pick the one that matches your styler.
How fast will it arrive, and can I change my mind?

Description
A diffuser for the Shark FlexStyle for curly or coily hair. It spreads the airflow over a larger area, so curls dry evenly from root to tip without being blown apart.
The prongs pull out when you want to reach the roots and add lift in thick or long hair, and slide back in for shorter styles.
Features
- Dries curls evenly from root to tip
- Extendable prongs reach the roots
- Made for curly and coily hair
- Available in Star Dust and black
