What Is It
The Redken Acidic Grow Full System Scalp & Hair Serum is a lightweight leave-in treatment designed to support fuller, thicker-looking hair while promoting a healthy scalp. Powered by Azelaic Acid and a 5% Strength Complex, the formula helps rebalance the scalp’s pH, deliver moisture, and strengthen hair fibers to reduce breakage. Ideal for thin or flat hair, this serum works at the roots to create instant lift and density while keeping the scalp hydrated and comfortable. With continued use as part of the Acidic Grow Full routine, hair looks stronger, healthier, and noticeably fuller.
