Redken Acidic Grow Full System Hair Serum 100ml is a pH-balanced scalp and hair treatment developed to target thin or flat hair with a visibly thicker-looking result. Scientifically proven to reduce hair fall due to breakage from brushing, it supports stronger-feeling strands while enhancing the appearance of density.
Powered by Azelaic Acid and a 5% Hydrating Complex, this lightweight formula helps rebalance and hydrate the scalp while delivering strengthening benefits that can lead to up to 2x less breakage compared to a classical shampoo in instrumental brushing tests on bleached hair. As part of the Acidic Grow Full System, including shampoo, conditioner and spray, it works to coat the hair fibre to reduce breakage and create the look and feel of fuller, denser hair as it grows. Hair appears revitalised, stronger and visibly thicker with continued use.
