The Healthier Way to Heat Style

Say goodbye to heat damage and hello to healthier styling.

KEEO Genius Pro+ is the world’s first styling tool with both heat and tension control. Its patented contoured plates with a protective air gap reduce tension by up to 70%, allowing hair to glide smoothly without tugging, pulling, or crushing the cuticle. This results in less breakage, frizz, and thinning, while maintaining your hair’s natural strength and shine.

  • Custom Heat & Tension – Full control with optimal styling temperatures and adjustable tension settings.
  • Smart-Glide Plates – Glide smoothly through hair, working with your hair's natural shape, not against it.
  • Ideal for All Hair Types – Perfect for fine, thick, curly, and damaged hair.

“Heat isn’t the only villain in hair damage — mechanical stress, like pulling and over-clamping, is just as harmful. The Genius Pro+ was designed not just to style hair, but to protect it.”

— Kate Holden, Trichologist

Different way of straightening

I didn’t realise how much my old straighteners were snagging my hair until I tried these! It’s only my first day with them and the technique is different to what I am used to, no clamping needed, they glide through my hair, and as it is high lift tinted I am grateful that the lower temperature does the job just as well. Thank you! ♥️

The only tools my hair actually listens to

Honestly, this is the best hair tool I’ve ever used. It delivers exactly what it promises with effortless styling and zero tension. It barely even feels like I’m straightening my hair, yet the results are flawless. Keeo have definitely solved it on this one.

I put it to the test by styling my hair in the morning and heading out for a few hours. Even seven hours later, my hair looked exactly the same. Normally, frizz would creep back in as soon as I’d been outside, but with this straightener there wasn’t a single sign of it. My hair stayed smooth, shiny, and perfectly styled.

I love that the Genius model is set at 190°C. It’s the perfect “sweet spot” for low-heat styling when I want to be a little kinder to my hair. That said, the Pro is my personal favourite. With my thicker, more stubborn hair, having the option of higher heat makes all the difference when I want more defined, long-lasting styling.

What really sets this apart is how well it tackles frizz. My Remington straighteners and Revamp curler never quite managed it without the help of anti-frizz serums, and even then, the results wouldn’t last nearly as long. With the Pro+, I get sleek, salon-worthy results that last all day with no extra effort.

I put together a little before and after comparison, the first is my hair after a wash and blow-dry, the second is just after styling and the third is 7 hours later.

I would 100% recommend this to anyone who wants smooth, frizz-free, long-lasting results without the extra effort.

KEEO Genius FAQ

Yes, the KEEO Genius has been designed for maximum respect for the hair while giving easy, beautiful results. Its patented smart-glide reduces all the stresses needed to heat style your hair to a minimum. As the world's kindest hair straightener, it's gentle even on damaged hair. Using 50% less tension means you'll feel and even hear how gentle it is, with the hair gliding through from root to tip compared to the pull and 'crackle' you might experience with flat-plate styling. And hair is cooler to the touch after styling because KEEO Genius is set at an optimal heat and isn't forced into the hair in the same way as flat plates. It's still important to take care of damaged hair using the right shampoos and conditioners and avoiding over-processing with chemicals.

Yes, KEEO Genius is the world's kindest hair straightener, so it is gentle even on the finest and most delicate hair. And because it reduces tension and compression, it won’t flatten the life out of your hair, leaving it feeling fuller while beautifully smooth.

Yes, KEEO Genius is brilliant on all hair types. Ensure you brush the hair before styling, style in smaller sections, and pass the styler slowly over each section. Due to 50% less tension, you may find the styler naturally wants to pass very quickly, so slowing down your speed will allow the plates to do their work. You'll get beautifully smooth hair.

Yes, the KEEO Genius is designed to work effectively on various hair types, including frizzy hair. Its contoured plates and air gap design help reduce tension and minimize frizz, leaving your hair smoother and healthier.

Yes. In addition to straightening, KEEO Genius is great for waves and curls. In fact, the plates and less tension make curling easy, bouncy and long-lasting.

The Original KEEO is set at 195°C, which we believe is the optimum temperature to style dry hair - gentle enough for all hair types, while warm enough to create a lasting style.

The KEEO Pro gives you the choice of three heat settings: 190°C, 200°C, and 210°C, so you can tailor styling to your individual hair needs.

In both tools, our unique contoured plates and protective air gap ensure heat isn’t forced into the hair, unlike flat-plate styling, leaving strands cooler to the touch even compared to stylers working at lower temperatures.

Titanium is an ideal coating for our patented contoured plates and air gap technology, as it is super hard-wearing (meaning they stay perfectly formed) and gives the most even heat distribution across the plate surface.

The unique patented contoured plates have a clever 'S curved' profile and a protective air gap between them. This gives just enough tension to beautifully smooth the hair without compressing it, reducing the pull/tension by 50% compared to conventional straighteners. It also reduces direct heat contact, meaning you'll notice hair is cooler-to-the-touch immediately after styling.

KEEO Genius delivers beautiful, smooth, healthy-looking hair results; the effortless glide can mean you pass rapidly through the hair. One pass is usually enough, but try slowing down your speed until you get the desired finish you are after.

Yes, KEEO Genius is dual voltage 230V 110V. Currently we only stock with a UK plug, so country-specific power adaptors are required outside of the UK.

At the moment, KEEO only ships within the UK, but international shipping options may be considered in the future.

Yes, KEEO offers a 30-day risk-free trial, allowing you to return the straighteners within 30 days for a full refund.
