Slow-growing hair; scalps that need a reset
Length starts at the scalp. This energizing leave-in serum stimulates and soothes the scalp while reinforcing new growth — the daily habit behind stronger lengths and healthier inches, month after month.
Powered by Kérastase's length-care complex:
- Creatine R Complex — fortifies hair from the root up
- Ceramides — protect fragile new growth
- Soothing leave-in texture — calms itchy, tight-feeling scalps
Best for: Daily scalp massage — 1-2 pipettes on towel-dried scalp, no rinsing
