BaByliss Diamond Heated Smoothing and Straightening Brush

Product Information

The brush is wide and allowed us to dry a lot of hair at once, cutting down our regular styling time. The retractable bristles are ingenious for preventing snagging and it’s a lovely tool to get to grips with if you’re new to hot brushes. You’ll recognise this chunky black device from TikTok, since it achieved viral fame on the app in 2020. You also get a luxurious heat resistant travel pouch, a magnetic charging dock and a magnetic charging cable with a 360C swivel feature. No hot plates anymore – the surfaces of the flat iron are easily touched by you, which might cause burns.

We’ve tried oval-shaped brushes on wet and damp hair, as well as thinner barrels too, some even with retractable bristles.Who doesn’t love a salon-quality blowout at home that leaves your friends wondering who your stylist is? And, if you want to cut down on styling time and heat stress, then a straightening dryer brush is an excellent investment. Keep an eye out for brushes that use ionic technology to moisturise your hair as you style, reducing damage and frizz. Those with finer or less dense hair can get away with using smaller tools since they have less hair that needs to be styled. Ten heat settings (from 120ºC for fine hair, up to 210ºC for thick and coarse hair) mean you can easily select the best temperature for your hair type.

And, as an added bonus, this brush comes with a travel bag, a glove for heat protection and two sectioning clips, making styling that little bit easier. The battery lasts for around 30 minutes and we managed to straighten our hair in just 7 minutes, meaning it should last a few styling sessions before your need to recharge. There are loads of hot brushes on the market though and they offer different finishes and work for a variety of textures – some suiting specific hair types more than others. That said, this brush doesn’t limit you to creating only poker straight styles either – with bristles on both sides, you can turn the brush as you use it.The only downside was that it required a little effort to get into our roots, meaning that you run the risk of leaving them slightly damp. It’s lightweight, small enough to fit in your handbag and features the same technology you’d expect to find in the brand’s standard plug-in models. Drew Barrymore’s Flower beauty and lifestyle range has consistently delivered simple but effective products that do what they say on the tin since its launch ten years ago. Flat irons are more suitable for thick, coarse hair, while straightening brushes are great for average to thin hair. In our roundup below, we haven’t included round brushes that are designed to lift the roots and deliver a more bouncy blowout style.

Heat styling can already be damaging to the hair, so by reducing the potential for pulling and catching, you’re helping to further prevent breakage. Always begin by spritzing the hair with heat protector spray to prevent any damage; this will stop your hair from snapping or splitting (check out our roundup of our favourite heat-protective products here). Unlike any of the other tools in this list, the allure is a cordless straightening brush that’s designed with bristles just like your regular hair brush.All of the straightening brushes that made our list are worth a try, but Drybar's Brush Crush Heated Straightening Brush stole our hearts. Fitting comfortably into the palm of your hand, the tool is an oval shape with a purple ceramic plate in the centre and a number of 3D, multi-length bristles surrounding it that are also coated with ceramic technology to prevent snagging. Straightening brushes are suitable for all hair types, but are especially effective on long, thick and wavy hair that resists easy smoothing with a flat iron. With a long cord and the lightweight design, we found that our arm didn’t get too tired during styling. A hair-straightening brush features a heated paddle (usually coated with ceramic – more on that below) with smoothing bristles, delivering the ease of a brush with the straightening power of a hot plate.
