Four 12.7mm Advanced Copper Ceramic Plates for superior even heat transfer, faster styling and ultra smooth glide A lot of hot hair tools, including most on our list, claim to release negative ions to protect your hair. I used to chalk this up to marketing-speak, but hairstylists I spoke with say ions are helpful.

COPPER-CERAMIC – Damage Control Technology - Advanced Copper Ceramic Technology for superior even heat transfer and Faster Styling T3 is the master of bespoke hair-styling experiences. But how do you get personal with straightening? You create a customized Heat ID profile that the T3 Lucea ID Smart Straightening & Styling Iron remembers, then styles your hair at its temperature sweet spot afterwards. That’s how.Our Copper Ceramic Dual Plate Straightener is finally here. First one of its kind. True innovative design in the straightener category. It all comes down to fewer passes. The first plate straightens, while the second reinforces for healthier-looking results with the copper ceramic plates with damage control technology. Great for fast and stylish results. Here are its Features: If you can look past its slightly odd shape, the Revlon Double Straight’s four-plate design makes a lot of sense. As you pass the Double Straight over your hair, the first two plates straighten, while the second two ‘reinforce’ the style. This effectively allows you to make two passes in one, which reduces both the time it takes to complete the style and the risk of heat damage. I found this to be largely true, although to get the full effect you need to pass it over your hair slightly slower than you would do normally, which cuts into the time-saving benefits a little. We liked the sleek design of these straighteners that come with a two-in-one protective storage sleeve that doubles as a styling mat. The ample three-metre swivel cord and slim handle meant it was comfortable in hand too, and they were ready to use in an impressively fast 15 seconds. Advanced Copper Floating Ceramic plates: Advanced Copper Ceramic Technology for superior even heat transfer and faster styling resulting in ultra-smooth glide in One Pass. Heat-wise, this Revlon offers the most temperature settings of any straighteners I’ve tried. There are 10 to choose from, ranging from 285 degrees Fahrenheit (140 Celsius) up to 455 degrees Fahrenheit (235 Celsius), which makes this a great choice for every hair type. I expected the copper ceramic plates to pull on the hair, due to the fact there are four of them and they’re so far apart, but they glide over it easily. The plates are also smaller than I had imagined—each one is 1/2 an inch whereas standard plates measure 1 inch—but they still cover similar widths of hair as standard straighteners. The biggest downside to the design is that it’s much harder to use these straighteners for curls. Not impossible, but difficult. — Victoria Woollaston-Webber

You might think steam would be the enemy of straight hair, but it actually moisturizes it while the heat flattens it into shape. According to L’Oreal, this allows the Steampod to gently dry the outer shaft without drying the core. When you go outside, especially in humid conditions, the hair then doesn’t absorb any of the extra moisture and remains frizz-free. If you have a non-Buy Now Pay Later balance on your Littlewoods account, you will still need to make at least Do use heat protecting products before drying or straightening your hair with any hair tools – be it a hair straightener, hair curlers or hot brush. I like to put on any cream or spray before hair drying so the product has more of a chance to sink into the hair follicles.'UP TO 2X FASTER STRAIGHTENING(*) – Dual Plate Design for Double Straightening Power and Faster Styling. (*vs Revlon RVST2043) If you buy the gift set you’ll get a protective heat guard, a heat-resistant style case that comes in handy when travelling and storing, and a styling tool kit with white croc clips and a comb. There are so many uses for hair straighteners, so a key thing to consider before purchasing is how (and how regularly) you’ll be using them. If you have coiled or frizzy hair that you straighten daily, floating plates and customizable heat that protect your hair’s health should be a priority. If you have fine hair and are as adept at how to curl hair with straighteners as you are smoothing, long narrow plates and a curved outer edge will make life a lot easier. What to consider when buying hair straighteners Straightening irons have come a long way over the years, and so have our expectations. In the early 00s, the idea that a tool could transform unruly, frizzy hair into sleek, smooth hair was enough, but now (like the Veruca Salt of beauty) we want it all, and we want it now. We want the ability to not just iron out kinks, but to create curls and waves too. We want to be able to enjoy cordless styling without needing to be near a plug. And we really, really, don’t want to compromise on hair health.

Heat control is central to the Corrale experience, with integrated sensors regulating the temperature of the smart plates 100 times per second. This means no hot spots or unwanted temperature spikes. We did find that hair felt cooler to the touch after passing through the iron than when using other straighteners on the same heat settings. Up to 2x Faster Straightening*: Reduce the time spent doing your hair with up to 2X faster results with only one glide. No loss of heat transfer and no need for glide after glide to get the look you want. Learning how to clean straighteners properly will stop your flat iron from accumulating a gunky combination of build-up heat protectant and styling products. This residue can inhibit the effectiveness of your flat iron. So, the cleaner your iron, the better the styling, and the more likely you are to achieve your desired style. It’s that simple. What type of heat protectant should I use? The best designs come with optimum heat settings or automatic heat modes that adapt to suit your hair. Heat plates that can maintain the heat output, or come infused with minerals, will also work well if your aim is to smooth frizzy hair. We asked celebrity hair stylist Katie Allan, founder of MayFive Hair, to trial a range of the latest hair straighteners in her London salon. Katie has styled hair for the BAFTAS and London Fashion Week and regularly appears on ITV’s This Morning. Her client list includes actor Gemma Chan and presenters Mel Giedroyc and Alex Jones, to name a few.

Not all hair needs to be fried between hot plates to straighten it. Some people can get soft, bouncy blowouts using a blow-dry brush rather than the old dryer and round brush combo. For coarser hair like mine, I recommend the RevAir below.

It feels premium and comfortable to hold and comes with a decent sized 2.7m cord, which meant we could move about (and dance to Friday night tunes in front of the mirror) while using it. At 520g, it’s surprisingly light in hand too considering its wider than normal heat plates. For peace of mind, after 30 minutes of inactivity, the irons will automatically shut off.
