Our take on the KERASTASE Genesis Bain NutriFortifiant Shampoo, 8.5 oz and Fondant Renforcateur Fortifying Conditioner, 6.8 oz

A two-piece Genesis set from Kérastase: a nourishing shampoo and a lightweight fortifying conditioner, both built around edelweiss native cells and ginger root to reduce breakage from brushing and styling. The shampoo cleanses without stripping, and the conditioner detangles weakened, fall-prone hair without weighing it down. It suits fine to medium hair that sheds or snaps, and it is gentler and lighter than heavy repair masks. Reviewers often note the fresh scent and softer hair, but some find the formula not rich enough for very dry or coarse hair.

Questions and answers

Does this set help with hair fall?
It is aimed at breakage-related fall: the formula fortifies strands so they snap less when brushed or styled. It does not treat hormonal or medical shedding, and results vary.
Is it good for fine hair?
Yes. The conditioner is lightweight and rinses clean, so fine hair keeps volume. Very dry or coarse hair may need a richer mask.
Can I use it on color-treated hair?
It is paraben-free and gentle enough for regular washing, and many color-treated users use it as their daily pair.
What is in the box?
One 8.5 oz shampoo bottle and one 6.8 oz conditioner bottle, both with pump dispensers.
How does it compare with the Genesis mask?
The conditioner is lighter and for daily detangling; the mask is thicker and for deeper repair on very damaged hair.
How often should I use it?
Most users wash and condition two to three times a week, adjusting to how oily their scalp gets.
