Pleasantly surprised
If I knew how good this products was I would have bought the bigger size. This is extremely light weight but also good with detangling wet hair

Game Changer
I'm grateful for the free sample of this product I got when I reordered my other Redken products. One pump of this serum after air drying my hair was a game changer, eliminating frizz almost instantly. I am obsessed with how my hair feels now. I have shoulder length hair, and one pump is perfect.
