Kérastase Genesis Fortifying Scalp Serum is the professional daily scalp serum that strengthens the hair fibre from root to tip to reduce hair loss due to breakage — formulated with Edelweiss native cells and ginger root to fortify the follicle environment and improve hair resilience with consistent use.
Hair fall due to breakage is different from hair loss caused by the scalp or follicle — it's structural damage at the fibre level that causes hair to snap before it can grow. Genesis Sérum Fortifiant targets this by reinforcing the hair's internal structure and supporting the micro-circulation at the scalp level where growth begins. Applied daily to the scalp and mid-lengths as a leave-in, it is the step that connects cleansing (Genesis shampoo) to visible density improvement over time.
Key Ingredient
Edelweiss native cells — a powerful botanical extract that strengthens the hair fibre from within and improves its resistance to mechanical stress from brushing, styling, and heat. Ginger root — stimulates scalp micro-circulation to support a healthier hair growth environment at the follicle level.
Best For
• Hair that breaks easily during brushing or styling
• Noticeable hair fall due to weakened or damaged fibres
• Hair thinning due to postpartum changes, stress, or hormonal shifts
• Anyone using the full Kérastase Genesis system for comprehensive density support
• Fine hair prone to breakage needing daily structural fortification
How to Use
1. Apply to clean, towel-dried hair — do not rinse out.
2. Section hair and apply directly to the scalp, massaging gently for 30–60 seconds to stimulate micro-circulation.
3. Distribute through mid-lengths and ends.
4. Style as usual — no rinse required.
5. Use daily for best results. Most clients notice reduced hair fall within 4–6 weeks of consistent daily use.
