Redken Acidic Bonding Concentrate Leave-In Treatment has become my favorite in the series. It is easy to distribute in towel-dried hair and makes a big difference for my dry ends. The hair feels shinier, less frizzy, and generally healthier. I also find that it protects well against heat when I style my hair. It doesn’t weigh it down, which is a big plus. Perfect as a finishing touch to hair care if you have damaged hair.
