Alterna Caviar Anti-Aging Restructuring Bond Repair Leave-in Overnight Serum helps repair and replenish damaged hair while you sleep. It is also suitable for color-treated hair, and the manufacturer recommends it for straight, wavy, curly, coily, and tightly coiled textures.

Key Benefits

The serum helps smooth cracks and irregularities in the hair cuticle layer, restore moisture, and enhance shine. In a clinical study, it reduced breakage by more than 99% compared to untreated hair.

The patented Caviar Bond Enforcing Technology is designed to seal the cuticle damaged by chemical processes or physical stress. Its molecules fill in cracks and help reduce friction along the hair fiber.

Overnight care thus combines moisture and shine replenishment with targeted support for the damaged hair cuticle.
