Hair Machine®

Powered by AI and futuristic tech innovation, Kérastase has taken the guesswork out of what your hair needs with a groundbreaking new innovation, K-Scan. The in-salon camera scans the hair and scalp to analyse exactly what your hair needs in seconds.

Behind the scenes, the team at Kérastase has been working on a top-secret innovation in scalp and hair care. And now, after more than two years in the making, we can proudly unveil K-Scan - an in-salon camera and companion app – that will help hairdressers to recommend ultra-personalised hair and scalp treatment to make you reach the hair and scalp routine of your dreams.

The technology has been trained on a data set of more than 12,000 images of women and men with all types of hair and scalp, to allow great accuracy of analysis. Developed through a collaboration between optical engineers, AI researchers, L’Oréal scalp & and hair experts, dermatologists, UI/UX designers, software engineers, and external engineering partners, K-Scan can accurately assess the condition of your hair and scalp.

The smart in-salon device, powered only by hairdressers, combines 3-light technology and a 4K resolution camera. Next, a highly accurate machine learning AI algorithm (trained by L’Oréal scalp & and hair experts) takes that imagery and reveals exactly what you need to focus on for your healthiest-looking hair and scalp.

It’s so groundbreaking that the Kérastase team presented K-Scan at VivaTech 2023, the world's biggest tech event that celebrates innovation and is described as ‘a gathering of the world's brightest minds, talents, and products’.

K-Scan: Revolutionising The In-Salon Experience

Since the 1960s, when we launched our first diagnostic tool Kérascope, we have been creating smart tech solutions to help hairdressers diagnose their clients’ needs. We have always understood that beautiful hair starts with a good assessment, offering effective in-salon and online tools like our quick hair quiz.

But K-Scan is our most innovative hair diagnostic tool yet. Basically, it takes images of your scalp and hair and then distills that information so your hairdresser can accurately recommend in-salon treatments and at-home products. What’s great is that with this tool you can see a comparison of your hair and scalp at the start of your visit and at the end, as well as setting goals for the future condition of your hair and scalp so that you can accurately track your progress through the companion app each time you visit your hairdresser.

How K-Scan Works

Now for the science part - stay with us, it’s fascinating. White LED light reveals surface features from sebum, hair fiber, and cuticle condition; cross-polarised white light removes glare and amplifies color differences accurately detecting capillaries, pigmentation, skin color, degree of redness and tone that can give a better picture of the overall scalp condition; finally UV light reveals what the naked eye cannot see - microorganisms and molecules such as porphyrins that become fluor red under UV light. “K-Scan’s 3 lights work in synergy, giving the user an in-depth and ultra-personalised hair and scalp diagnosis. K-Scan lights act as eye-amplifiers,” says Edine Ahbich, Global Scientific Director for Kérastase. Every detail of your scalp is captured in high definition.

K-Scan enables hairdressers to give a high standard of in-depth analysis at the consultation every time and from there your hairdresser can recommend in-salon and at-home care. What’s more, with K-Scan the consumer can see instant before and after results via the app’s imaging technology. “With skincare, consumers need to wait, on average, 21 days (about 3 weeks) to see the after results of a treatment, but with K-Scan consumers will be able to see the positive changes in their hair and scalp right after their treatment,” notes Aurelia Baudelaire Consumer Experience Director for Kérastase Global team, managing tech innovations, online services, CRM & data.
