Kérastase Spécifique Stimuliste is the professional scalp serum formulated with Aminexil — a clinically studied molecule that targets the scalp environment to support micro-circulation, reduce the rigidification of collagen around the hair follicle, and improve the conditions for denser, stronger hair growth.
Stimuliste works at the scalp level, where the conditions for hair growth are determined. Aminexil, the core active, is clinically studied to prevent the progressive rigidification of collagen around the hair root — one of the key mechanisms behind hair thinning as the follicle's anchor weakens. The serum is massaged into the scalp 2–3 times per week as a leave-in, progressively improving the density and quality of the hair growth environment. It is Kérastase's most targeted clinical solution for thinning and is recommended by professional stylists across Canada for clients experiencing noticeable density loss.
Key Ingredient
Aminexil — a clinical molecule derived from minoxidil research, studied to preserve and restore the scalp's micro-circulation around the hair follicle and reduce the collagen rigidification that limits anchoring of the hair root. SA-Palmitate — an anti-DHT active that addresses androgenetic thinning factors at the scalp level.
Best For
• Visible thinning or reduced hair density
• Hair loss associated with hormonal changes, menopause, postpartum, or aging
• Clients whose stylists have recommended a targeted scalp treatment
• Anyone who has used Nioxin and wants a clinical Kérastase-level alternative
• Thinning in Metro Vancouver's hard water environment (mineral buildup can compound scalp-level thinning)
How to Use
1. Part the hair into sections to expose the scalp.
2. Apply Stimuliste directly to the scalp — do not rinse out.
3. Massage gently for 1–2 minutes to encourage absorption and micro-circulation.
4. Style as usual.
5. Use 2–3 times per week. Results typically visible within 6–8 weeks of consistent use.
