The Sapiens Anti-Hair Loss Serum is a concentrate of natural active ingredients to reduce hair loss, stimulate regrowth, and strengthen the hair fiber sustainably. It acts directly at the root to promote stronger, thicker, and more resilient hair. Its natural formula (99.4%) combines 4 powerful active ingredients: AnaGain™, Capilia Longa (turmeric), D-Biotin (vitamin B8), and Bioflavonoids. Together, they restart growth, slow down hair loss, strengthen the hair, and improve scalp microcirculation. Easy to apply thanks to its dropper, this serum leaves no greasy effect or residue. Use it daily, preferably in the evening on a clean, dry scalp. Gently massage to penetrate. Formulated without silicone, parabens, or mineral oil. Made in France. Approved by barbers.
