What Comes in the Duo?
- Bain Nutri-Fortifiant Shampoo: the cleansing step, with a rich texture designed for normal to dry, weakened hair.
- Fondant Renforçateur Conditioner: a lightweight conditioning step for softness, easier detangling, and care of the lengths and ends.
Who Should Consider It?
Consider this pair if your hair feels dry and weakened and you want to replace both your shampoo and conditioner. Kérastase positions Genesis around hair fall caused by breakage from brushing. It is not a treatment for hair loss originating at the root.
If you only need one step, buying that item separately may make more sense than replacing both. If your main priority is an oil-focused cleansing routine or fragrance-free care, review the formula and product selection before choosing this duo.
Texture and Fragrance
The pairing combines a richer shampoo with a lighter conditioner. The Genesis fragrance has a woody citrus profile, so scent preference is part of the decision.
How to Use the Pair
- Apply the shampoo to wet hair, lather, and rinse. Repeat as directed by the manufacturer.
- Apply the conditioner to shampooed, towel-dried lengths and ends, avoiding the scalp.
- Leave the conditioner on for 2 to 3 minutes, then rinse thoroughly.
Follow the instructions on the products you receive. If either product enters your eyes, rinse immediately and thoroughly.
Quick Questions
Does the duo include a scalp serum?
No. This selection contains a shampoo and a conditioner.
Is the conditioner a leave-in?
No. Fondant Renforçateur is a rinse-out conditioner.
Is the kit necessarily cheaper than buying separately?
No. Compare the current total prices and bottle sizes before deciding.
Our Take
This duo makes the most sense when both steps fit your routine and both need replacing. Choose it for the specific shampoo and conditioner included, rather than the Genesis name alone. If one of your current products already works well, consider replacing only the step you need.
