Kérastase Genesis — a night routine against hair loss and winter dryness

Central heating, dry air and shorter days make hair thin faster and feel more fragile in winter — Genesis is the fortifying routine for exactly that.

Kérastase
Genesis — shampoo, conditioner and serum

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.
