Rated 5 out of 5 by from I’ve been using the Redken Acidic Bonding Concentrate Serum 100ml for a while now and one of the biggest differences I noticed is how much fuller and thicker my hair feels. My hair used to look flat and lifeless, especially at the roots, but after consistent use it feels more voluminous and healthier overall. The serum helps smooth damaged strands without making the hair heavy, which means the hair keeps its natural bounce and movement. My hair looks denser, feels stronger when brushing, and has a much healthier texture from root to ends. I also noticed less breakage, which makes the hair appear thicker over time. Another thing I love is that it controls frizz while still giving body and volume, something many serums fail to do. The lightweight formula leaves the hair soft, shiny, and lifted instead of greasy or flat. It gives that fresh salon finish and makes styling much easier. Overall, this serum made my hair look healthier, fuller, and more alive, and I would highly recommend it for anyone wanting stronger hair with more thickness and volume.
