Mask for deep, long-lasting reconstruction of brittle, dry and damaged hair. Formulated with an active complex containing amino acids, vegetal keratin, vegetal collagen and mineral salts which, by restoring cellular cohesion, repairs and strengthens the hair fibre from the inside out. It rebalances porosity, leaving the cuticle compact, and improves the elasticity of the hair, which is immediately stronger, shinier and silkier.
