The Shark SpeedStyle Pro Flex is a folding version of Shark's compact dryer, aimed at people who want curl-friendly tools in something that packs small. It folds to half its size, according to Shark, and includes a DefrizzFast diffuser among four attachments. That mix of travel-friendly design and a proper diffuser is what sets it apart from most folding dryers.

In its favour
- The listing names defined curls among its results with the diffuser.
- Heat and airflow auto-adjust when you fit the diffuser.

Good to know

Our take
The folding design
Shark says the handle folds to half its size for storage in bags, carry-ons or drawers. The listed weight is 680 g, which is light for a dryer with four attachments, though the spec table shows a 2.19 kg packed weight. A UK plug is fitted, and the listing does not mention dual voltage, so overseas travel may need checking.
Rated power is 1,700 W with three settings listed.
Four attachments with auto-adjusting settings
The kit includes a Turbo Concentrator, DefrizzFast Diffuser, QuickSmooth Brush and FrizzFighter Finishing Tool. Heat and airflow adjust automatically for each one, so the diffuser does not need you to find the right speed manually. A cool shot setting locks in styles.
Scalp Shield mode reduces air temperature for scalp comfort and root drying, designed to protect new hair growth from extreme heat.
Curly hair routine
For curls, the DefrizzFast Diffuser is the key head, and the auto-adjust feature should keep airflow gentle enough not to disturb curl patterns. The FrizzFighter can then tidy flyaways on dry hair. Shark lists the dryer for all hair types. A sensible order is to rough-dry with the concentrator, switch to the diffuser while hair is still damp, then finish with a cool shot. Because the settings follow each head, the routine needs fewer button presses than a standard dryer. If you sometimes wear your hair straight, the QuickSmooth Brush covers that too.
Pro Flex against the SpeedStyle Pro and Dyson Curly+Coily
The Shark SpeedStyle Pro has five attachments, adding an Express Touch-Up Brush, and a stated 662 g, but does not fold. The Dyson Supersonic r Curly+Coily adds a wide tooth comb and Dyson's intelligent attachments in a compact non-folding format. The Pro Flex is the one to choose if folding storage tops the list.
Verdict
The SpeedStyle Pro Flex suits curly or wavy hair owners who travel or have little storage space and want a diffuser included. If folding is not needed, the Shark SpeedStyle Pro adds a fifth attachment, and for a textured-hair kit with a comb, compare the Dyson Supersonic r Curly+Coily.
