The floating ceramic plates heat up evenly, and it’s easy to operate the tool using a single button that controls both power and heat selection. The cordless straighteners are perfect for styling on the go and come with a handy travel bag.

Revlon Smoothstay Coconut-infused hair straighteners: The best budget straighteners for a glossy finishKey specs – Plates: Ceramic-coated, “floating spring” plates; Heat settings: 185ºC; Maximum temperature: 185ºC; Voltage: Universal; Cord length: N/A; Automatic shut-off time: 3 minutes; Warranty: 2 years The Platinum Plus is GHD’s premium offering, with floating ceramic plates designed to deliver optimum heat for your hair type and maintain that temperature using intelligent heat technology that measures and adjusts it constantly while styling. The result is even heat across the plates that won’t scorch the hair, leaving hair looking glossy and feeling healthy. The smooth gliding plates and even heat distribution mean you won’t have to run the Platinum Plus through the same strands more than once to see results, and the wishbone-shaped hinge reduces the risk of catching or snagging hair as you style.

Straightening tools that use tourmaline plates can achieve optimum results at lower temperatures, so if you straighten your hair often you may want to consider spending a little more on a tool that can be used effectively on cooler settings. This will result in less heat damage. Straight hair will never go out of fashion, so neither will the best hair straighteners you can use to achieve it. Research by consumer-trends analyst Mintel suggests that over one-third of women and one-fifth of men own a set of hair straighteners, and that number is growing. GHD and Cloud Nine are the dominant names in this market, but an ever-growing number of brands promise super-sleek, frizz-free straightening and more besides. The Contouring Iron also comes equipped with an impressive temperature range, with 11 temperature settings between 100°C and 200°C. There’s also a “Revive” mode, which fixes the temperature at 150°C, but uses micro-vibrations in the plates during styling to help create longer-lasting styles, despite the low heat. This is a step up from the Cloud Nine Original Iron, featured above, and worked remarkably well in our testing. There’s no getting around the fact that this is an expensive curling iron, but it’s the perfect all-in-one styler for those willing to splash out. If you’re in the market for a versatile straightening tool that can handle both straight and curly styles with ease, the Babyliss 9000 is our recommendation. Beauty heavyweight Revlon offers a simple but good-value option in these straightening irons. The ceramic coating on the floating heating plates is infused with moisturising coconut oil, paired with ionic technology to maintain hydration in the hair shaft and discourage frizz and flyaways.Key specs – Plates: Floating; Maximum temperature: 200ºC; Voltage: 100-240V; Cord length: 3m; Automatic shut-off time: 30 minutes; Warranty: 3 years All hair straighteners work by heating the hair using metal plates. This causes the hydrogen bonds in the hair to break (a process that also takes place when the hair is wet). The straightening tool then passes over the hair, holding it in a new, flat position. The hair retains this new shape as it cools and the hydrogen bonds reform. If the hair is wrapped around the tool rather than held straight while cooling, then the hair will take on a loose curl shape instead. Launched by one of the founders of GHD, Cloud Nine’s Original hair straighteners glide easily through the hair without any pull or drag. They leave hair feeling silky, looking shiny, and – most importantly – poker straight. Hair health is a key drive of this product’s design: the ceramic plates are mineral-infused to reduce snagging, leaving hair with extra shine, and there are six heat settings, from 100ºC to 200ºC. The plates perform well at lower temperatures, which means less risk of damage to hair.
