AG Hair's Vita C Repair Serum is a lightweight, leave-in hair serum formulated with a stable vitamin C derivative and plant-based squalane to help repair dry or damaged strands. Unlike a rinse-out treatment, this serum is designed to stay on the hair: apply it to damp hair, then blow-dry or let hair air dry, with no rinsing needed. Its blend of conditioning silicones and botanical extracts, including calendula, lavender, and clover, coats and seals the hair shaft, which helps smooth texture, add shine, and cut down on breakage and split ends over time. Hydrolyzed vegetable protein and butylene glycol add further moisture and softness.
The formula is vegan, cruelty-free, and free of sulfates, though it is not silicone-free — several silicones, including dimethicone and amodimethicone, are part of what gives it slip and shine. It's best suited to dry, damaged, or chemically treated hair that needs extra smoothing and protection, and works well as a finishing step before styling.
