Kérastase Specifique Stimuliste is a daily stimulating spray against hair-loss. The special active ingredient complex has an energising and nourishing effect on the scalp and roots. Aminexil prevents the hardening of the collagen layer and softens already hardened parts in order to prevent the roots from suffocating. Arginine stimulates the scalp and hair production, while vitamin PP enhances circulation in the scalp and also improves the moisture level. Gluco-lipids strengthen the hair fibre and provide new energy for the lifecycle of the hair.
