See the future of your hair.
K Scan reveals the real health of your scalp and hair on screen, with a live before and after after a single treatment. Understand your hair like never before, then get a plan made just for you.

A window into your hair
Real answers, not guesswork.
K Scan is a clever little camera and AI diagnosis from Kérastase. Using three lights and a microscopic 4K lens, it captures your scalp and hair in remarkable detail, then reads it in seconds against thousands of expert images. In other words, we stop guessing and start seeing exactly what your hair needs.
You watch it all happen on screen, and leave with a plan built entirely around you.

What it reveals
Scalp wellness
An overall wellness score for your scalp, the foundation of healthy hair.
Hair density
How much hair you have across the scalp, measured, not guessed.
Hair diameter
The thickness of each strand, so we can spot fine or weakening hair early.
Scalp redness
Signs of sensitivity or irritation that can hold your hair back.
Dandruff
Flaking and build-up, so we can calm and rebalance the scalp.
Hair-fall risk
An early indicator of shedding, so we can act before it shows.

How it works
Three simple steps.
Quick, gentle and genuinely fascinating to watch.

See it on screen
Kérastase's AI reads the images in seconds and shows your results on a tablet, in real detail you can actually see and understand.

Your personalised plan
Your stylist talks you through what it means and builds a plan, the right in-salon treatment and a simple routine for home.
See the difference
A live before and after, visible immediately after only one salon treatment.
We scan, we treat, and we scan again, so you can see your own results side by side on screen. It is the most rewarding part, and proof that your plan is working from day one.
