Pros
- Exceptional versatility with one device handling drying, curling, volumizing, and smoothing
- Lightweight and portable design makes it ideal for travel and everyday use
- Comprehensive accessory kit eliminates need for multiple styling tools
- Intelligent heat control minimizes damage while maintaining styling effectiveness

The Shark FlexStyle represents a significant innovation in multi-styling tools, combining a professional-grade hair dryer with a versatile multi-styler in one compact device. This tool is designed for anyone looking to simplify their hair routine without sacrificing quality, whether you're a busy professional, frequent traveler, or someone who enjoys experimenting with different styles at home.
The standout feature is undoubtedly the one-twist transformation mechanism that seamlessly switches between drying and styling modes. With six included attachments (auto-wrap curlers, oval brush, paddle brush, curl-defining diffuser, and concentrator), you can curl, volumize, smooth, and dry your hair without needing a separate styling tool collection. The intelligent heat control system actively reduces heat exposure during styling, making daily use safer for your hair health.
Build quality appears solid with a combination of durable, heat-resistant plastic and metal components weighing just 1.5 pounds. The compact 13.5-inch length and lightweight construction make it genuinely portable, fitting easily into travel bags or bathroom drawers. The 1600-watt motor delivers professional-level power despite the compact size, with three speed and heat settings plus a cool shot function for versatile styling options.
The main limitation is the corded design, which restricts movement compared to cordless alternatives. Additionally, without established customer reviews, it's difficult to assess long-term durability or real-world performance consistency across different hair textures. The learning curve for switching between modes may initially feel awkward for new users.
The Shark FlexStyle is an excellent investment for anyone seeking a space-saving, damage-conscious styling solution that performs multiple functions. Its universal compatibility with all hair types and comprehensive accessory kit make it a practical choice for households with diverse hair care needs.

Comparison Considerations: Unlike single-function tools, the FlexStyle combines drying and styling in one device. While cordless options exist, this corded model offers consistent power delivery and eliminates charging concerns during styling sessions.

The Shark FlexStyle Marilyn Monroe Limited Edition is a premium multi-styling system that combines a powerful hair dryer with interchangeable attachments for complete hair styling versatility. This 2-in-1 device is designed for anyone seeking professional salon results at home, whether you have straight, wavy, curly, or coily hair. The limited edition collaboration features over 20,000 crystals, making it as beautiful to display as it is functional to use.
The standout feature is Shark's intelligent temperature regulation technology, which measures and adjusts heat output 1,000 times per second to maintain consistent air temperature throughout your styling session. This means you get powerful, fast drying without the heat damage typically associated with traditional hair dryers. The system includes 1.25-inch auto-wrap curlers with Coanda Technology that automatically curl and set hair, plus an oval brush and concentrator attachment for complete styling flexibility.
Despite its professional capabilities, the FlexStyle weighs just over 1.5 pounds and operates at 1600 watts, delivering impressive power in a compact, lightweight package. The metal, plastic, and rubber construction feels durable, and the ergonomic design makes it comfortable to hold during extended styling sessions. The multiple attachment options mean you can achieve curls, volume, smooth styles, and quick drying without switching between multiple tools.
The main consideration is the premium price point, which positions this as a luxury styling investment rather than a budget-friendly option. Additionally, while the device is lightweight, its corded design means you'll need access to a power outlet during use. Without existing user reviews, potential buyers should rely on Shark's reputation for innovative hair care technology and the product's comprehensive feature set.
Overall, the Shark FlexStyle Marilyn Monroe is an excellent choice for style-conscious consumers who want professional results, advanced heat protection technology, and the versatility to create multiple looks with one device. If you prioritize innovation, build quality, and styling versatility over price, this limited edition system delivers exceptional value.

Who Should Buy This Product: The Shark FlexStyle Marilyn Monroe is ideal for anyone with multiple hair types in their household, style enthusiasts who want versatile styling options, and consumers who prioritize heat protection technology. It's particularly well-suited for people with curly or coily hair who want automatic curling capabilities, as well as those seeking a professional-grade tool that doesn't require multiple devices.
Key Considerations: Evaluate whether the premium price aligns with your budget and styling needs. Consider your access to power outlets if you plan to travel frequently, as the corded design limits portability. If you have minimal styling needs or prefer ultra-budget options, more affordable alternatives may suffice. However, if you value advanced heat regulation, versatility, and professional results, this investment pays dividends.
Comparison Factor: Unlike basic hair dryers, the FlexStyle combines multiple styling tools into one device, potentially reducing the need to purchase separate curling irons, volumizing tools, and dryers. The intelligent temperature regulation sets it apart from standard multi-stylers by prioritizing hair health without sacrificing speed or performance.
Pros
- Versatile for all hair types and lengths.
- Dual bristle combination for effective smoothing and volume.
- No heat damage protects hair health.
- Specifically designed for Shark FlexStyle, ensuring perfect fit and performance.
- Lightweight and easy to use for quick styling.
Cons
- Only compatible with Shark FlexStyle systems, not universal.
- May not be suitable for very long or thick hair as it is best on short to medium lengths.
- Requires purchase of the Shark FlexStyle base unit separately.
The Shark FlexStyle Round Hot Air Brush Attachment is a targeted accessory for the Shark FlexStyle Air Styling & Drying System. It is designed for users who want to smooth, defrizz, and add volume and bounce to their hair while drying, without subjecting strands to extreme heat. This attachment is best suited for short to medium-length hair, bangs, and layers, and works on all hair types including straight, wavy, curly, and coily.
Standout features include the combination of boar and nylon bristles that effectively grab and smooth the hair while delivering airflow for volume and bounce. The attachment allows you to style and dry simultaneously, reducing styling time. Real-world performance is enhanced by the no heat damage benefit, as the FlexStyle system uses controlled airflow rather than intense heat, making it a healthier option for daily styling.
Build quality is typical of Shark accessories: lightweight at 0.24 pounds and compact dimensions of 3.25 x 3.25 x 5.5 inches. The stone color matches the FlexStyle base unit aesthetically. The attachment clicks securely onto the FlexStyle, ensuring stable operation during use. The bristles are sturdy enough to handle various hair textures without pulling.
One drawback is that this attachment is only compatible with the Shark FlexStyle systems (HD400 series), so it cannot be used with other blow dryers. Additionally, while it works on all hair types, it is optimized for short to medium lengths and may not provide the same results on very long or thick hair. Finally, the base Shark FlexStyle unit must be purchased separately, which is a significant investment.
Verdict: The Shark FlexStyle Round Hot Air Brush Attachment is a valuable add-on for existing FlexStyle owners. It delivers effective styling with heat protection, but its utility is limited to the specific host system. If you already own a Shark FlexStyle and frequently style your hair, this attachment is a worthwhile purchase for achieving salon-like volume and smoothness.
Pros
- Fast and even drying with deep bowl construction
- Adjustable prongs accommodate different hair lengths and textures
- Helps maintain natural curl volume and definition
- Designed specifically for Shark FlexStyle for optimal performance
- Lightweight and easy to use
Cons
- Only compatible with FlexStyle HD400 series, not other Shark dryers
- May be bulky for some users, making it less travel-friendly
- Primarily designed for curly/wavy hair, not for straightening
The Shark FlexStyle Curl-Defining Diffuser Attachment (XSKHD4DA) is a specialized accessory for the Shark FlexStyle HD400 series hair dryers. It is designed for users with curly or wavy hair who want to achieve faster drying times while maintaining natural volume and definition. The diffuser features a deep bowl to handle larger sections of hair, reducing overall styling time.
One standout feature is the adjustable prong system. Users can switch between extended and retracted positions via a lever. Extended prongs are ideal for longer, thicker hair as they lift the root and promote volume. Retracted prongs are better for shorter, finer hair, providing gentle coverage and reducing heat on the scalp. This versatility makes the attachment suitable for a wide range of hair types.
The petal design of the diffuser helps create a more natural hold on curls, preventing frizz and maintaining bounce. The attachment is lightweight and easy to clip onto the dryer, ensuring a secure fit. However, it is only compatible with the Shark FlexStyle HD400 series, so owners of other Shark dryers like FlexFusion or SpeedStyle will need to look elsewhere.
Potential drawbacks include the limited compatibility and the fact that the diffuser is primarily for curly/wavy styling, not for straightening. Some users might find the attachment a bit bulky for travel, but it performs well for its intended purpose. The price point is reasonable for a branded accessory that delivers professional-quality results.
Overall, the Shark FlexStyle Curl-Defining Diffuser Attachment is a solid investment for anyone with curly hair using the FlexStyle dryer. It cuts down drying time, enhances volume, and offers adjustable settings for different hair lengths. While it may not be universal, it excels within its ecosystem.

The Shark FlexStyle IonCurl is a 2-in-1 hair dryer and multi-styler that leverages ion technology and Coanda airflow to dry, curl, and style hair without heat damage. It is particularly suited for individuals with straight or wavy hair who want to add volume and curls while minimizing frizz. The system comes with several attachments, making it a versatile tool for daily styling routines.
The standout feature is the powerful Coanda wrap curling, which automatically attracts and wraps hair around the curler for bouncy, defined curls in seconds. The ion-powered air helps smooth frizz and static, providing up to 24 hours of shine when used with the FrizzFighter polisher. The Scalp Shield mode is a thoughtful addition for those concerned about heat exposure, and the Airset Button gives users precise control over airflow.
The FlexStyle IonCurl is built with a sleek blue finish and weighs 1.5 pounds, which is manageable for extended use. The attachments are easy to swap, and the overall design feels sturdy. However, the lack of a carrying case or storage bag may be a minor inconvenience for travelers.
The FlexStyle IonCurl is a significant investment compared to traditional curling irons or hair dryers. Additionally, it is configured specifically for straight and wavy hair; users with very curly or coarse textures might not achieve the same results without additional accessories. As a new product, there are no user reviews to confirm long-term reliability.
Overall, the Shark FlexStyle IonCurl is an innovative styling tool that delivers on its promise of no-heat-damage curls and frizz control. It is ideal for those who value versatility and hair health.

Buying Guide
Coanda Technology: The Core of Curl Definition
The IonCurl model stands out with its CoandaBoost technology, which uses enhanced airflow to wrap hair around the curler automatically. This reduces the need for high heat, helping to maintain your hair’s natural moisture. If you have struggled with curling irons that leave your ends dry, this feature is a game changer. The standard FlexStyle also uses Coanda but with slightly less airflow, so the IonCurl is the best pick for defined, long-lasting curls.
Versatility: More Than Just Curls
All FlexStyle systems transform from a hair dryer to a multi-styler with a simple twist. You can attach auto-wrap curlers, a round brush, a concentrator, or a diffuser. This means one tool replaces multiple devices. For instance, the Shark FlexStyle, Air Multi-Styler & Drying System (HD435) includes a diffuser, making it ideal for curly hair. The IonCurl adds extra curl power, while the Marilyn Monroe limited edition sparkles with crystals. Think about your daily styling needs: if you want volume and smoothness, the round brush attachment is a great add-on.
Heat Control: Protecting Your Hair
All FlexStyle models use intelligent heat control that measures temperature 1,000 times per second. This ensures consistent heat without spikes, reducing the risk of damage. The IonCurl takes this a step further by lowering the temperature during the curling process. For those with fine or color-treated hair, this is a crucial consideration. We have seen similar heat protection in other brands, like the Shark SilkiPro Straightener, but the FlexStyle offers the added benefit of drying and styling in one.
Attachments and Compatibility
Shark offers a range of add-ons such as the round hot air brush and the curl-defining diffuser. These are compatible only with the FlexStyle HD400 series. If you want to upgrade later, the attachments are sold separately. The HD435 already includes a diffuser, while the IonCurl comes with two auto-wrap curlers. Check your primary styling needs: if you have shorter hair, the round brush is excellent for bangs and layers. The diffuser’s extended prongs are great for longer, thicker hair.

Final Thoughts
After evaluating the entire FlexStyle lineup, we believe the IonCurl is the top choice for anyone who prioritizes defined, frizz-free curls with minimal heat. However, if you need a versatile everyday tool that also handles diffusing and smoothing, the Shark FlexStyle, Air Multi-Styler & Drying System (HD435) offers excellent value with its included diffuser. Both models deliver salon-quality results without the damage, so your choice comes down to your specific styling habits. Whichever you pick, you are investing in a reliable system that adapts to your hair type.
Frequently Asked Questions
Can the Shark FlexStyle IonCurl be used on wet hair?
Yes, the FlexStyle is designed to dry and style in one step. You can use it on damp hair, but for best results, towel-dry your hair to remove excess moisture first. The IonCurl works especially well on slightly damp hair to create defined curls.
How does the IonCurl compare to the standard FlexStyle?
The IonCurl uses CoandaBoost technology for stronger airflow, which helps the hair wrap around the curler more easily. It also has an improved heat control system that reduces temperature during curling. The standard FlexStyle (HD440BK) is still excellent for general styling, but the IonCurl is the best for curl definition.
Is the FlexStyle safe for all hair types?
Absolutely. The FlexStyle is designed for straight, wavy, curly, and coily hair. It comes with multiple attachments to suit different textures. For example, the diffuser is great for curly hair, while the round brush adds volume to straight or wavy hair. The intelligent heat control ensures safety across all hair types.
What attachments are included with the IonCurl model?
The Shark FlexStyle IonCurl (HD840PU) includes two auto-wrap curlers, an oval brush, and a concentrator nozzle. It does not come with a diffuser, but you can purchase the Shark FlexStyle Curl-Defining Diffuser Attachment separately. If you need a diffuser from the start, consider the HD435 model.
