Abril Et Nature Instant Mask Keratin  delivers a dual-action keratin treatment that repairs hair from both surface and interior. Larger keratin molecules form a protective film sealing the cuticle, while smaller fractions penetrate the cortex to restore strength and resilience from within. Formulated with hydrolyzed keratin closely resembling natural hair protein, this mask effectively revitalizes damaged hair, improving texture and durability. Its carefully selected ingredients ensure deep nourishment and long-lasting repair for healthier, smoother hair.
