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. Read our article to treat dandruff.

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.

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.

THE K SCAN MEASURES THE FOLLOWING PARAMETERS:

Porphyrin - a molecule, revealed by UV light, that is secreted by the microbiome and supports scalp health.

Dandruff - UV light can detect pools of dead cells that the naked eye can sometimes miss.

Fiber diameter - analysed with white light, this information can help optimise product recommendations.

Root density - the white light can also pick up on the number of hairs per cm2.

Powered By Artificial Intelligence

"With each volunteer, we spent 2 hours doing in-depth analysis, analysing different locations of the head with the 3 light modes."

The AI algorithm Kérastase uses is exclusive, developed in-house for all hair types and that is a key element “that will enable us to better understand our consumers and empower hairdressers to give them ultra-personalised recommendations,” says Aldina Suwanto, K-Scan Project Manager at L’Oréal Research & Innovation. The algorithm relies on training data to recognise patterns and make predictions regarding scalp attributes like dandruff, scalp redness, hair density, and hair diameter.

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.
