Editor's Pick: The shampoo creates a nice dense lather, with a natural rosemary scent and no artificial slipping feel. With added biotin and caffeine, it leaves a slight cooling sensation on the scalp after washing. After blow-drying, the roots feel lifted, and even fine hair gains a bit of volume.
