Subrina Professional Care Keratin Mask is a richly textured pampering cream designed to provide intensive nourishment to extremely dry, chemically treated, and damaged hair. Formulated with high-quality keratin, shea butter, and saccharide isomerate, it rebuilds the natural protective layer of hair fibers from the inside out. This deep-conditioning mask restores elasticity, prevents breakage, and leaves hair deeply nourished, extraordinarily shiny, and silky smooth.
