Suzanne, I erred. The product Marcie used was Redken's "Smooth Down", and the bottle says it "tames frizz on even the most rebellious hair"
The "Straight" she did not use. That product says, "kick out kinks, curls and frizz with humidity resistant smoothness". It behooves all of us with this problem to just keep trying till we find something that works. I think I even brought this along for you to try on Black Sea, and forgot to share it! I think you have to buy them at a salon.
