byTun has created a unique beauty ritual which sublimates hair in three steps by bathing, treating, and texturising it using proven application techniques.

This simple three-step programme, in combination with with Kérastase treatments, introduces women to a new hair-routine, which they can then continue at home so as to unleash their hair’s full potential progressively over time.

The first step of the ritual, the bath with its accompanying gestures, melting texture, subtle perfume, and scalp massage, prepare scalp and hair to receive the full benefits of the treatment.


This powerful and targeted treatment acts in depth. The transformation is felt instantly, as hair regains its strength and remains enhanced over a long period.


This last step protects the hair and prepares it for blow-drying or styling.
