Heat-Protective Silk-Straightening Cream by Kiehl's
My hair tends toward frizz all the time and my bangs basically point straight up if I don't blow them out. (Annoying.) This is my favorite straightener, although I find it's most effective when I use about twice as much as I think I should. I also like Bumble and bumble's Straight but I kind of OD'd on the line when I was working at a hair salon that used their products exclusively. I can still smell the Alojoba shampoo.
I recently tried a sample of this and absolutely LOVED it. I'm definitely picking up a tube. The small sample packet lasted nearly a week, during which I applied a dime like size amount throughout my hair evenly before styling. It's light, greaseless, and virtually odorless, but gives my hair a really nice shine.
