ALL HAIR CONCERNS
CAN BE TREATED

A custom diagnosis is the secret to
beautiful hair.

Since 1994, Kérastase has applied the
powerful principle of proper diagnosis
to luxury haircare. The approach was
game changer then, and it remains a
crucial part of our DNA.

We believe hair evaluation is even more
relevant in the modern world. Our fast-
paced lived and varied environments
bring constant changes to the hair.

The only way to keep up is to check in
regularly and tine un to what the hair
needs.

ANSWERS TO COMMON QUESTIONS

Unlike static quizzes, our Generative AI interprets the nuances of your beauty profile. It processes thousands of combinations of hair types, scalp concerns, and environmental factors to curate a high-precision prescription that is uniquely yours, evolving as your needs change.

True luxury is adaptive. By integrating Environment Inputs, we tailor your ritual to your local climate, protecting the hair fiber from the specific stressors of your immediate surroundings.

Our AI-powered diagnostic is designed to bring Kérastase professional expertise to your fingertips, offering a medical-grade analysis in just 120 seconds. While it provides a highly accurate home-care routine, it also serves as a perfect prelude to your next in-salon treatment, allowing your stylist to further refine your ritual.

We recommend updating your diagnostic every season or whenever you travel to a new climate. As environmental inputs and your hair's condition change, our AI adapts your prescription to ensure your ritual remains perfectly synchronized with your life.
