Genesis is Kérastase's fortifying line for weakened hair that sheds or breaks more easily. The Bain Nutri-Fortifiant is a strengthening shampoo for dry or thick, weak hair: it gently cleanses, nourishes and strengthens the hair fibre to reduce the risk of hair loss. The formula combines ginger root and edelweiss stem cells, topped with antioxidants that protect the fibre from everyday influences and give the hair natural resilience. Kérastase advises combining the shampoo with the Fondant Renforçateur or the Masque Reconstituant. In the evening the 8H Magic Night serum joins in, working while you sleep with plant proteins and niacinamide. That way the routine works both by day and by night, instead of only one of the two. In winter, when dry air makes hair break more easily, it's a logical moment to start.


A combination that works by day and by night, not just one or the other.


Blond Absolu — the ritual against dull, brassy tones
Blonde hair loses its shine fast in winter from dry air and central heating. Blond Absolu keeps the tone bright and the hair soft, ritual after ritual.

Kérastase Nutritive — nourishment for hair that feels dry
Central heating and cold winter air strip moisture from hair — Nutritive restores it with plant-based proteins and niacinamide, all the way to the ends.

Chronologiste — the ritual for her and her scalp
Chronologiste isn't just another wash — it's a moment of indulgence that calms the scalp and nourishes hair from root to tip.
