According to ghd, in a consumer testing panel of 142 women, there was no thermal hair damage detected after 100 cycles of 4 passes of the tool in wet-to-style mode compared to naturally dried hair. These are impressive stats, but the cynic in me still doesn’t quite believe that any tool powered by heat won’t damage the hair at least a little bit. Instead of saying it doesn’t cause any damage at all, I would lean towards saying that the ghd Duet Styler results in reduced damage compared to using a separate hairdryer and straightener. Keep in mind too that even air drying your hair, which is widely considered to be the kindest option, can still cause some damage. This is because our strands are weaker when they’re wet and are therefore more prone to snagging and snapping caused by things like brushing, combing and friction on your pillow. Can you use the ghd Duet Styler on dry hair? My whole head of hair took less than 30 mins to style – for a lazy girl with a lot of hair, that's pretty impressive. What's more, because the hair tool isn't as streamlined-looking as others in my arsenal, I was worried it would be heavy and make my arms ache like I'd done a weight session at the gym, but it's actually pretty light considering all the tech, weighing just 0.821 kg.

If you have what I would call easy hair (can get caught in the rain without fear of frizz and leave the house without heat styling) then the ghd Duet Style isn’t going to set your heart on fire. But, if like me, you blow dry and straighten your hair every single time you wash it, then it's really worth it. ghd claims that their unique 'Air-fusion' tech (sounds science-y, right?) allows for ultra concentrated airflow to effectively dry and straighten hair at a lower temperature. Thus, avoiding stripping the hair of its natural moisture and minimising damage. If you’re serious about straightening and smoothing, but also serious about the health of your hair, I’d say the ghd Duet Style is worth the investment. FAQ Does the GHD Duet really not damage hair?

Once all your hair is completely dried, for an optional boost of shine, activate Shine Shot™ by pressing down the Shine Shot™ button for 4 seconds until you hear a beep (Shine Shot™ should only be used on dry hair.) The fan will stop and the plate temperature will increase to the optimal ghd styling temperature of 365°F. Once the product beeps and the lights stop flashing, Shine Shot™ is ready. Your Duet Style can now be used as a regular flat iron. Take each section of your hair and hold the Duet Style at the root for three seconds to ensure it's properly dry. Then glide the tool through the lengths around four times, just like you would a straightener. Work your way through each section until the hair is totally dry—and you're done. Straightening and drying in one.Introducing the revolutionary ghd duet style - the first 2-in-1 hot air styler* that dries and styles hair at the same time with no damage**. Slide the power button upwards to turn ON your Duet Style. After a few seconds you will hear the fan ramp up as it heats up to the optimal low styling temperature for wet hair. Once the light stops flashing and the product beeps, it is ready to use.

As I’ve alluded to, the ghd Duet Style looks, at first glance, like a big straightener – but it’s much more than that. The magic starts with the swivel cord, where a filter draws air into the styler to fuel the drying process. That air is then propelled up the handle of the styler to the plates. There, instead of a typical double-plate design, there are four narrow plates (two on each side) with air vents between them where the heated air is blown onto the hair. There are also four narrow rows of vents on the outer edges of the Duet, which are designed to efficiently dry your roots. If you have curly or wavy hair and like to blow dry your lengths to be straight, this tool will revolutionise your routine—I'm absolutely certain of that. The extra heat and clamping motion sets it miles above any blow-dry brush or multi-styler out there for this sort of thing. If that's you, please don't let anything else that I'm about to say put you off. On paper, my ghd Duet Style review was a success, but there was a moment post-styling where I looked at my rod-straight hair and wondered if ghd is 10 years too late with this innovation. Even straight-hair coveters like me have graduated to the idea of a soft wave instead of poker straight hair. ghd doesn’t mention waving or curling hair with this product, but I thought I’d give it a go. Using the shine shot, I was able to add a subtle wave to my hair, which made my finished style feel softer and more modern. The plates are wide, so this wouldn’t be possible on short hairstyles, just shoulder-length to long hairstyles and it takes a bit of practice to get the technique right (even if you already know how to curl hair with a straightener) Yes, the whole way in which you use it takes some adjusting to, but personally, I think it's fantastic. As somebody with long, fine, thin hair, I found that using the GHD Duet Style actually gave my hair way more lift at the roots than I'm used to achieving at home. My hair was full of volume and looked like it was in optimal health.

The Verdict:

Instead of exposing my hair to the high heat of a hairdryer, followed by a straightener temperature of 185°C, the max it got to was 150°C (without the shine shot). My hair felt soft, healthy, and not-at-all frazzled after use. Yes, you can't really create anything else but poker-straight strands ( mermaid waves and tight curls are sadly out of the question) but it really does what it says on the tin. I'd never seen my hair this healthy-looking after using a hair tool.
