Recommended hair styler
Such a good hair styler.. even as a dryer, it dries the hair very fast. Its not very loud compared to my old hair dryer. I originally got it for the brush, and I’m so happy with it! I bought during end of financial year for a very affordable price as well. I would definitely recommend it!

At a glance
The Shark FlexStyle Air Styling And Drying System Stone is a multi-styler and hair dryer in one, designed for people who want flexible everyday styling without juggling several tools. It suits straight, wavy, curly and coily hair, with useful attachments, light weight and temperature regulation as key strengths. One limitation is that it offers fewer attachment options than some premium salon-focused multi-stylers.

Things to consider
It is highly versatile for home use, but specialist salon tools or more premium styling systems may offer a broader attachment range or more advanced customisation.
Styling versatility score
9/10 - Multiple attachments support drying, curling, smoothing and volumising across a wide range of styling routines.
Hair type suitability
Suitable for straight, wavy, curly and coily hair
Travel friendliness
6/10 - Lightweight for its category, but better suited to home use due to its full-size multi-styler format and attachment set.
Ease of use rating
8/10 - Auto-wrap curlers, adjustable settings and a lightweight body make it approachable for regular home styling.
Salon results suitability
8/10 - Strong styling flexibility and frizz control make it capable of polished results at home, though dedicated salon tools may offer more specialised precision.
Key benefits
- Interchangeable Attachments: Lets you dry, curl, smooth and volumise with one main tool instead of switching between multiple separate stylers.
- 35 mm Auto Wrap Curlers: Helps create curls in both directions with less manual wrapping, making styling easier for everyday users.
- Coanda Technology Attachment: Helps tame frizz and flyaways for a smoother finished look.
- Temperature Regulation: Measures and regulates air temperature to help reduce the risk of heat damage during regular styling.
- Three Heat Levels Plus Cool Shot: Gives you flexible control for setting styles and adjusting heat to suit different hair needs.
- Lightweight 0.66 kg Main Unit: Reduces arm fatigue during longer styling sessions.
- 2.8 m Cord: Provides extra reach around vanities and mirrors for more comfortable movement while styling.
- 1650 W Motor: Delivers strong airflow for faster drying performance than lower-powered styling tools.
Q: Can the Shark FlexStyle HD421SL replace a separate hair dryer and everyday styling tools?
A: Yes. This model switches between a hair dryer and multi-styler, and includes a concentrator, oval brush and two auto-wrap curlers. It can replace several everyday tools, but it is not the same as a dedicated hot plate straightener for pin-straight finishes.
Q: Is the Shark FlexStyle HD421SL suitable for thick, long or curly hair?
A: Yes. Its 1650W motor, multiple heat and airflow settings, and styling attachments make it suitable for straight, wavy, curly and coily hair types. For very thick or long hair, styling in sections will usually give faster drying and better shape control.
Q: How do the auto-wrap curlers work on the Shark FlexStyle HD421SL?
A: The system includes two 3.5cm auto-wrap curlers, one for each curl direction, so both sides of the head can be styled evenly. They work best when hair is mostly dry rather than soaking wet, which helps the curl form and hold more consistently.
Q: Is the Shark FlexStyle HD421SL a lighter option for self-styling?
A: Yes. The main unit weighs 0.66kg without attachments, which helps reduce arm fatigue during drying and styling. The 2.8m cord also gives more reach around mirrors or vanities, though the overall feel becomes slightly heavier once an attachment is fitted.
Q: Can the Shark FlexStyle HD421SL help reduce frizz without using very high heat?
A: Yes. It monitors temperature 1000 times per second and uses Coanda airflow to attract and smooth hair while styling, which helps limit heat stress. It is designed to tame frizz and add shine, but very coarse hair may still need more than one pass or sectioning.
Q: Is the Shark FlexStyle HD421SL a good alternative to premium air stylers?
A: For buyers comparing premium air stylers, this model offers similar core versatility with drying, smoothing and curling in one unit.
