Designed to combine powerful drying performance with innovative curling and smoothing technology, this versatile multi-styler helps you create a wide range of hairstyles without needing several separate appliances.

Whether you prefer soft waves, defined curls, a smooth blow-dry or a voluminous finish, the Shark FlexStyle IonCurl provides the flexibility to experiment with different looks at home.

Powerful Drying and Versatile Styling

At the heart of the Shark FlexStyle IonCurl is a powerful 1750W system designed to deliver high-velocity airflow for efficient drying and styling.

This makes it a practical choice for busy mornings, evening preparations and regular haircare routines. Rather than relying on a conventional hairdryer followed by several separate styling tools, the FlexStyle IonCurl allows you to switch between different attachments to achieve your preferred finish.

Its advanced airflow technology is designed to style without causing heat damage under Shark’s stated testing conditions, offering an alternative to some traditional high-temperature styling methods.

Create Beautiful Curls with CoandaBoost Technology

One of the standout features of the HD840UKPU is its advanced CoandaBoost Technology.

Using the Coanda effect, the curling barrels attract and wrap sections of hair around the barrel using directed airflow. This helps reduce the need to manually wind hair around a traditional curling wand and makes curling more convenient.

Shark states that CoandaBoost Technology provides a stronger wrapping effect than the original FlexStyle, helping create bouncier and more defined curls under its stated testing conditions.

The HD840UKPU includes two 32mm Coanda Curling Barrels, giving you the tools to create soft curls, flowing waves and a variety of curled finishes.

Whether you’re preparing for a special occasion or adding movement to your everyday hairstyle, the curling attachments offer a convenient way to achieve a polished look.

Smoother-Looking Hair with Ion-Powered Airflow

The Shark FlexStyle IonCurl features advanced ion-powered airflow technology.

Designed to deliver 200 million negative ions, the system helps reduce static and improve frizz control while drying and styling.

This can help create a smoother, shinier-looking finish compared with air drying, particularly when combined with the appropriate styling attachment and technique.

For an even more polished result, the included FrizzFighter High Shine Polisher helps smooth visible flyaways and improve the appearance of your finished hairstyle.

It’s a useful finishing attachment when creating sleek blow-dries, smooth everyday looks or polished styles for special occasions.

Add Volume with the Oval Brush

For anyone who enjoys a bouncy blow-dry, the included Oval Brush provides another versatile styling option.

Designed to work with the appliance’s airflow, the brush helps smooth hair while adding shape, body and volume.

It’s particularly useful for creating lift near the roots, adding movement through the lengths and styling the ends of your hair.

Whether you’re preparing for a busy day or getting ready for an evening out, the Oval Brush helps you achieve a fuller-looking finish with one convenient attachment.

Precise Drying with the Styling Concentrator

The included Styling Concentrator provides more directed airflow for controlled drying.

This attachment is useful when you want to focus the airflow on particular sections of hair or prepare your hair before curling.

It can also be used alongside a suitable styling brush to help create a smooth, controlled blow-dry.

With several interchangeable attachments included, the FlexStyle IonCurl makes it easy to adapt your styling routine to different hair lengths, textures and desired results.

Intelligent Scalp Shield Mode

Shark’s Scalp Shield Mode is designed to help protect delicate new hair growth from excessive heat.

When activated, the appliance adjusts its temperature settings to provide a more controlled styling experience when working closer to the roots.

This thoughtful feature is particularly useful for everyday drying and styling and demonstrates Shark’s focus on combining performance with haircare technology.

Greater Styling Control with the AirSet Button

The innovative AirSet button adds convenience to the styling process.

Double tapping the button pauses airflow, allowing you to reposition your hair or move between sections more easily.

A single tap delivers a burst of cool air, which can help set a curl or style after warm airflow has been applied.

These convenient controls make it easier to manage your styling routine without unnecessary interruptions.

Designed for Different Hair Types and Textures

The Shark FlexStyle IonCurl is designed to work across a wide variety of hair types and textures.

Whether your hair is straight, wavy, curly, fine or thick, the combination of adjustable styling settings and interchangeable attachments allows you to personalise your routine.

Different styling techniques and accessories can be used to achieve a range of results, making the appliance suitable for households with different styling preferences.

Comfortable Handling and Convenient Storage

Despite its powerful performance, the FlexStyle IonCurl is designed with comfortable handling in mind.

The styling unit weighs approximately 0.68kg, making it relatively lightweight and easy to manoeuvre while styling different sections of your hair.

Its slim design is practical for everyday use, while the 2.44-metre power cord provides flexibility when styling near a mirror or dressing table.

The included storage bag provides a convenient place to keep the appliance and its accessories together, helping prevent smaller attachments from becoming misplaced.

One Styling System, Multiple Looks

From everyday blow-dries to defined curls, soft waves and sleek finishing touches, the Shark FlexStyle IonCurl HD840UKPU offers a versatile approach to home hairstyling.

Its combination of powerful airflow, advanced curling technology and interchangeable attachments makes it a practical choice for anyone looking to simplify their styling routine.
