I found outOur Top Picks12Shark silkipro straight hair straightener and dryer, plum satinRead review£250Buy nowFew launches rivalled the Dyson airstrait when it debuted and kickstarted the wet-to-dry styling trend. But earlier in 2026, the Shark silkipro launched, and with it, posed one big question: can it deliver the same sleek finish for less? Both devices promise to dry and straighten hair simultaneously, eliminating the need for separate hair dryers and straighteners, but they take very different approaches. As someone who’s tested my fair share of hair tools, I put them head-to-head. To do a fair test, I used both tools side by side on the same wash day, styling half of my hair with each before comparing everything from drying speed and smoothness to ease of use, heat exposure and overall finish. While the results were closer than I expected, one styler ultimately proved more impressive.Read more: Best hair dryers, reviewedWhen put side by side, the resemblance between the two devices is uncanny (Lucy Smith/The Independent)Read more: Best hot brushes, tested1Dyson airstrait straightenerWhy we love it Dries and smooths faster than Shark, even on hefty sectionsLack of hot plates help to minimise heat damageTake note ExpensiveHuge plug attachmentShow moreThe Dyson airstrait was one of the most intriguing launches in haircare when it debuted, largely because it ditched traditional hot plates in favour of a precisely directed airflow that dries and straightens hair simultaneously. The promise was a streamlined approach: your hair dryer and straighteners into one slick tool, cutting both costs and time. (At £450, though, you can buy a high-quality dryer and straightener for the same price, if not less.)The tool has separate wet and dry styling modes, three heat settings, two airflow speeds and a small LCD to let you know which mode you’re operating. It also features an automatic pause mode that cuts the airflow after a few seconds of putting the tool down, and restarts as soon as you pick it up again. This helps you to save energy and, if you’re guilty of a “Did I turn the straighteners off” panic, this function will give you peace of mind. The display makes it easy to monitor what mode, temperature and speed you're using (Lucy Smith/The Independent)The plates can be locked together to allow you to rough-dry your roots and I’d recommend taking your hair from wet to damp by rough blow-drying if you have thick hair. The styling process is the same as if you were to straighten your hair. Try as I might, though, to give some flick to the ends, I’ve never found the bounce to last. My hair was looked and felt soft and frizz-free after use (Lucy Smith/The Independent)When in use, the biggest strength against Shark’s iteration is its speed. The airstrait spreads hair evenly across the arms, creating more tension and drying larger sections thoroughly in a single pass. On my naturally straight-to-wavy hair, I consistently needed fewer passes than with the Shark, cutting my styling time by around two to three minutes overall. The finish was sleek, soft and impressively shiny, and my hair had none of the telltale signs (for example, a burning smell or frazzled ends) of heat damage. While it performs exceptionally well, it’s a seriously expensive tool. The oversized plug, which is about the size of a mango, also isn't at all travel-friendly. The Shark silkipro plug (left) vs the Dyson airstrait plug (right) (Lucy Smith/The Independent)If minimising heat damage is your priority, Dyson still has the edge. Without ceramic plates making direct contact with the hair, it delivers excellent results using air alone, making the £450 sum easier to justify for frequent users who style their hair straight several times a week.

But the tool takes a slightly different approach to achieving the results it promises. It combines high-velocity airflow with ceramic plates that continuously regulate temperature, allowing it to work as both a wet-to-dry styler and a conventional straightener (when used in dry mode). It also includes three interchangeable smoothing combs, designed to grip everything from fine, straight hair to thicker, curlier textures more effectively.Like the Dyson, it can be locked closed to double as a hair dryer. I found this worked best for rough-drying rather than replacing a dedicated dryer. It also has a cool setting so that you can lock in your style. One criticism shared by both tools is the size. Neither gets especially close to the roots in wet mode, meaning the hair around my crown took a little longer to dry and smooth than the mid-lengths and ends. I achieved the same smooth result with the Shark silkipro, albeit with longer spent styling (Lucy Smith/The Independent)Testing it side by side with the Dyson, I was surprised by just how close the results were. Although the silkipro took more passes to fully dry each section, the finished style was every bit as poker straight and static-free. In fact, one feature I preferred was how securely it held larger sections of hair between the plates. Where the Dyson occasionally let thicker sections slip out, the Shark kept everything neatly contained, making it feel more like using a traditional straightener (probably because it’s more similar to one). The plug is also significantly smaller, making it a more practical option for packing into an overnight bag. That said, the ceramic plates mean you're introducing more direct heat than with the Dyson, so it won't appeal to anyone looking to seriously minimise heat exposure, especially because it requires more passes and contact with the plates for a 100 per cent dry result. If your priorities are value, versatility and achieving a salon-sleek finish without spending £450, the silkipro is an incredibly viable option and comes remarkably close to matching the category leader.Key specificationsModes: Wet and dry Heat settings: 6 (3 in wet, 3 in dry – all different)Airflow speeds: 3Weight: 0.78kg Cable length: 2.44mVoltage (check if travelling abroad): 230V Read more: Shark’s glam vs Dyson’s airwrap: which hair multi styler is better? Back to topWhat's better, the Dyson airstrait or Shark silkipro? If you're looking for the fastest wet-to-dry styling experience with the least possible heat exposure, the Dyson airstrait remains the better tool. It dried my hair in fewer passes, created more tension through each section and relies solely on airflow rather than heated plates.That said, the Shark silkipro gave the Dyson a proper run for its money – for £200 less. The end result was almost indistinguishable on my hair, making it the smarter buy for most people. Unless minimising heat damage is your top priority or you style your hair straight several times a week, I'd save the money and choose Shark.How we testedI've been testing the Dyson airstrait for more than a year, using it one to two times a week as part of my regular wash routine. Meanwhile, I first got my hands on the Shark silkipro in March 2026 and have been using it consistently for the past few months. For this comparison, I styled freshly washed, towel-dried hair with both tools side by side, using one on each half of my head to compare the results in real time. I assessed each styler on:Speed: I timed how long each tool took to dry and straighten my hair from around 80 per cent dry.Ease of use: I judged how intuitive the controls were and how comfortable each tool felt to manoeuvre, including how well they gripped onto the wefts of hair.Styling performance: I compared how many passes were needed to fully dry and smooth each section.Finish: I looked at shine, frizz reduction, static, smoothness and how long the style lasted.Hair protection: I considered the level of direct heat exposure, alongside any signs of dryness or damage after repeated use.Design: I evaluated weight, cable length, plug size, versatility and features such as the hair dryer mode and (for Dyson) automatic shut-off.
