Instituto Espanol Argan And Keratin Repairing Shampoo 750ml

Reformulate compromised strands with a silicone-free blend of argan oil and hydrolyzed keratin, specifically engineered to rebuild tensile strength in dry, chemically processed, or heat-stressed hair.

The formulation relies on hydrolyzed keratin molecules calibrated to integrate into cracked cuticle layers, effectively filling the micro-fissures that trigger split ends and mechanical breakage. Paired with concentrated argan oil, the mixture restructures weakened surface fibers along the shaft, restoring flexibility and improving moisture retention from roots to ends. Because the recipe excludes silicone polymers, the cleanser rinses without depositing heavy residue. This transparent finish allows subsequent leave-in reparative treatments to bind directly to exposed cortex zones rather than sliding off sealed filaments.

Designed as a foundational step in a structured repair routine, this 750 ml formula delivers sustained reinforcement through regular washing. Apply to wet hair, massage the mild lather through the lengths for two minutes to distribute the active matrix, and rinse thoroughly. The extended bottle volume supports consistent maintenance cycles for longer hair or frequent restoration needs, preserving structural integrity between deep conditioning applications.
