Is Shark FlexStyle Good for Thick Hair?

The Shark FlexStyle is a 4-in-1 air styling system that combines the functions of a hair dryer, curling iron, and hairbrush in one innovative device. It was introduced in 2022 and quickly became one of the most talked-about hair tools due to its flexible shaft and ability to dry and style simultaneously. The key difference between the FlexStyle and a standard blow dryer is the inner bend that allows the wand to twist into an L-shape, making it easier to style the back of your head without needing a second pair of hands. The FlexStyle operates on the principle of Coanda airflow, which is a technique that creates a drying and styling effect by pulling hair toward the ’canister’ with air rather than trapping it in a heated clip or edge. This means you can curl or straighten with less heat damage, reducing the risk of hair damage that plagues traditional curling wands. The motor generates up to 1600 watts of power, rivaling many dedicated hair dryers but delivering a more concentrated airflow for styling. It comes with several attachments that click into the wand magnetically. The auto-wrap barrels (available in different sizes) wrap hair just by bringing the barrel close, making curling nearly effortless. The round brush and smoothing brush help in blowouts and sleek finishes, while the diffuser is perfect for curly or coily textures. The tool also includes a concentrator nozzle for focused drying and a cool shot button to hold styles. The included travel bag is a bonus for those who like to style on the go.

Thick hair is more about volume and density than individual strand thickness. There are roughly 100,000 hair follicles on a person’s head, and those with thick hair have more follicles than average, which makes their hair heavier and more massive. Thick, dense hair takes significantly longer to air dry and to blow dry, and it often becomes a frizzy mess if not handled carefully. Heat and airflow need to be evenly distributed throughout the entire head to avoid a partly-dry, partly-wet situation. For daily styling, thick hair requires a tool that can handle large sections at once without overheating. The airflow needs to be strong enough to penetrate to the roots and dry the underlying layers. A narrow nozzle will increase speed but may cause concentrated heat damage. A wide barrel or oversized brush is also helpful to wrap more strands per curler. Finally, grip and maneuverability are essential as styling sessions can be long. There are several specific challenges that thick hair faces: 1. **Drying time**: It takes 2–3 times longer to dry thick hair compared to fine hair. 2. **Curls falling flat**: Heavy hair pulls curls down, shortening their lifespan. 3. **Frizz**: Excess moisture and uneven drying lead to frizzy texture. 4. **Stylist fatigue**: Holding a heavy tool while working through dense hair is tiring. Shark FlexStyle aims to address these by offering a powerful motor, multiple attachments, and a flexible design that reduces strain. But how well does it actually perform on thick heads of hair? Let's dive in.

When evaluating the Shark FlexStyle for thick hair, the first and most important factor is its drying power. With a 1600-watt motor, it produces an air speed of up to 190 km/h, which is impressive for a styling tool. For many thick-haired users, this translates to a significant reduction in blow-drying time compared to regular hair dryers. The concentrator nozzle helps direct air precisely, allowing you to dry the roots and middle hair first. Users with thick hair often report that the FlexStyle cuts their drying time by 30–50%, although it might still be slightly slower than the Dyson Supersonic or the T3 Cura. The Coanda airflow technology is the standout feature for thick hair. It makes curling much easier because you don't have to manually wrap each section perfectly. Just bring the barrel close to hair and the airflow pulls the hair onto the barrel, creating a curl. For thick hair, this is both a blessing and a curse. The blessing is that it minimizes heat damage and provides even heating, which helps the curl set. The curse is that thick hair is heavy, and the curls may not hold their shape for long, especially if you have long, dense hair. Many reviewers suggest using a small section size (one-inch sections or smaller) and letting each curl cool on the barrel for a few extra seconds. Another area where the FlexStyle excels is the variety of attachments. The smoothing brush is excellent for sealing the cuticle and reducing frizz in thick hair. The round brush helps create volume and bounce. The diffuser is a godsend for thick curly or wavy hair. It distributes air widely, preventing the frizz that plagued many thick-haired users who used a normal dryer. The flexible wand also makes it easier to reach the back of the head without awkward contortion, a key benefit when styling thick hair that requires lots of vertical and horizontal manipulation. However, no tool is perfect. The FlexStyle’s curling barrels are relatively narrow (0.95-inch and 1.25-inch). For thick hair, this means you have to work in small sections to get all the hair into the barrel. We've seen complaints that the 1.25-inch barrel is still too small to wrap large sections, making styling time longer. Also, the barrel can overheat if you have very long thick hair, because the hair retains the heat for a long time. Some users with coarse thick hair have reported that the curls drop after an hour, much to their disappointment. Weight and ergonomics are another consideration. The FlexStyle weighs about 1.5 pounds, which is on the heavier side for a styling tool. When styling thick hair, you’re lifting it repeatedly, which can cause arm fatigue. The flexible bending point can also feel less stable than a rigid wand, especially when applying tension to the hair. Users with long thick hair have said the wand sometimes feels less sturdy than they'd like. In comparison to the Dyson Airwrap, the FlexStyle is approximately 25% cheaper but lacks the Airwrap’s multi-barrel options and its powerful yet lightweight motor. The Airwrap also has a longer barrel (1.2 inches) and a better curl-holding performance on thick hair, but many users argue the FlexStyle offers 80% of the Airwrap's capability at half the price. If you’re on a budget but still want to cut down your drying and styling time, the FlexStyle is a compelling option. Having said all that, the FlexStyle shines in one particular area for thick hair: the diffuser. Users with naturally curly thick hair report that the diffuser delivers excellent definition and minimizes frizz, often outperforming dedicated diffusers from other brands. The bendable wand allows you to position your head at awkward angles, making it easier to diffuse your roots without craning your neck. Overall, the Shark FlexStyle has a lot going for it for thick hair, but it is not a magic solution. It performs best as a blow dryer and diffuser, but its curling attachments are the weaker link. If you have thick hair and are considering the FlexStyle, it’s essential to have realistic expectations about curling and to be prepared to use additional hairspray or techniques to hold curls.
