Kérastase Genesis Sérum Anti-Chute Fortifiant is a daily leave-in scalp serum for weakened hair prone to falling due to breakage. Powered by Aminexil, it anchors the hair fibre at the root and reinforces the scalp — the targeted daily step in the Genesis anti hair-fall routine.

Benefits
  • Reduces hair fall due to breakage — significant efficacy after 6 weeks of use (clinical study, 99 people).
  • Anchors hair at the root — improves resistance and resilience.
  • Soothes the scalp — reduces itchiness and discomfort after 3 weeks.
  • Non-drip jelly texture — for precise, targeted scalp application.
How to use
  1. Use once daily for a 6-week course, on a dry or towel-dried scalp.
  2. Apply section by section, up to 4 doses (one full pipette each), and massage in with fingertips.
  3. Do not rinse, then style as usual. As part of the full Genesis system: up to 84% less hair fall due to breakage.

From the Partners Hair team
Kérastase Genesis Sérum Anti-Chute Fortifiant is a daily leave-in scalp serum for weakened hair prone to falling due to breakage. Powered by Aminexil, it anchors the hair fibre at the root and reinforces the scalp — a targeted daily step in the Genesis anti hair-fall routine.

Best for: weakened hair with increased fall from brushing, styling or breakage; a daily strengthening routine; scalp discomfort or itchiness.
Less suited to: those wanting a rinse-out product (this is leave-in, do not rinse); hair loss originating from the scalp or follicle — Genesis targets breakage, not medical hair loss (see Kérastase Spécifique).

Key actives:
- Aminexil — reinforces hair anchoring at the root, reduces fall
- Edelweiss Native Cells and Ginger Root — strengthen the fibre
- Supporting actives: Caffeine, Arginine, Niacinamide, Resveratrol, Tocopherol

Benefits:
- Reduces hair fall due to breakage — significant efficacy after 6 weeks of use (clinical study, 99 people)
- Used as part of the full Genesis system: up to 84% less hair fall due to breakage (instrumental brushing test vs non-conditioning shampoo)
- Anchors the hair fibre at the root
- Soothes scalp discomfort and itchiness (after 3 weeks)
- Reinforces the scalp's natural protective barrier
- Lightweight jelly texture for targeted, non-drip scalp application

How to use: Once daily over a 6-week period. Apply to dry or towel-dried scalp section by section, up to 4 doses (one dose = one full pipette). Massage in with fingertips. Do not rinse. Style as usual.
