Highlighted in the brand's Genesis fortifying approach.

Who Should Consider It?
Consider it if breakage-focused care is your priority and a daily scalp application fits your habits. Kérastase explicitly states that Genesis is not a hair-loss product. Do not choose it on the assumption that it treats genetic hair loss or guarantees regrowth.
How to Use
Part the hair and apply directly to the scalp using the pipette. The brand defines one dose at the black dosage line and directs users to apply up to four doses, massage to distribute, and leave in. Follow your bottle's directions; application can fit a towel-dried routine or use between washes.
What to Consider
A daily leave-in should suit your scalp and fragrance preferences as well as your schedule. The brand's headline breakage percentage is based on a specified Genesis system, so it should not be read as a demonstrated result from this serum alone.
Quick Questions
Is it used like 8H Magic Night Serum?
No. Genesis Serum Fortifiant is applied to the scalp; the Nutritive night serum is intended for lengths and ends.
Should I rinse it out?
No. It is a leave-in serum.
Does it replace shampoo or conditioner?
No. It is a separate scalp-care step.
Our Take
The useful distinction is a daily scalp serum within a breakage-focused routine. Shortlist it when that purpose matches your needs and you are comfortable with regular application. If your concern is hair shedding from the root, identifying its cause is more useful than treating this cosmetic serum as a regrowth solution.
