Gentle on my course damaged hair

I really like this straightener - a nice change to years of using GHD. There is no pulling and straightens my shoulder length hair quickly. It would be slightly smoother I expect if I used any products but I don't due to allergies. My air quality monitor confirms using this straightener does not create as much particle matter to be released into the air - another massive plus for me. I won't be going back to using my former pair that's for sure!

brilliant 👏

I must admit I have never heard of this brand until I read an advert in Daily Mail.
Did some research and thought about it for a few days, then decided to go for it. I have to say very glad I did, they seemed strange at first with not being totally straight, but they really are great and I very glad I have them.

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.

KEEO Genius is set to 190C, which we believe is the optimum temperature to style dry hair. It is cool enough to be gentle on all hair types, whilst being warm enough to create lasting style. Our air gap also ensures the heat isn't forced into the hair, unlike flat-plate styling, meaning the hair is left cooler-to-the-touch versus other stylers working at 180°.

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.
