Redken Acidic Grow Full System Instant Densifying Spray 190ml is a lightweight leave-in treatment designed to combat the signs of thin or flat hair. Developed to create thicker-looking lengths, it is scientifically proven to reduce hair fall due to breakage from brushing while supporting a fuller appearance from root to tip.
Powered by Azelaic Acid and a 5% Densifying Complex, the formula helps deliver visible body and lift without heaviness. It supports scalp hydration for a rebalanced feel while providing instant root-lifting and enhanced thickness. As part of the Acidic Grow Full System, including shampoo, conditioner and serum, it works to coat the hair fibre to reduce breakage and create the look and feel of denser hair as it grows. Hair appears fuller, stronger and visibly revitalised with continued use
