K-Scan
The future of hair & scalp analysis thanks to AI
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.
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.

AND WHAT EACH LIGHT IS ANALYSING
UV LIGHT
PORPHYRIN & DANDRUFF
Porphyrin is a molecule, revealed by UV light, that is secreted by the microbiome and supports scalp health: As Dandruff is caused by skin cells that regenerate too fast leading to a build-up of flakes, this can be detected by K-Scan’s camera.
CROSS-POLARISED LIGHT
ITCHY-FEELING SCALP
K-Scan’s camera is able to see your scalp in detail, which can help it understand what could be causing an itching-feeling and dry scalp and how to fix it.
WHITE LIGHT
GREASINESS
If you feel like you’re always needing to wash your hair, then it’s likely your scalp is producing too much sebum - something K-Scan’s white LED light can detect.
