Sexy, voluminous hair may look effortless on TV, but those of us with fine strands know that taking them from flat to full can be tricky. All too often, the products that are supposed to thicken our tresses end up weighing them down, and even if we do achieve a va-va-voom look, in a few hours, our manes inevitably revert to their naturally lifeless state. But fortunately, I've just stumbled upon duo that delivers on its volumizing promise: Jonathan Product Create Volume Thickening Foam and Brushable Lifting Spray ($24 and $28; sephora.com). After applying the lightweight mousse post-shower, my damp strands felt smooth, manageable, and ready for styling. And once I finished blow-drying, the results were impressive—fuller, sexier hair without the sticky residue. The Brushable Lifting Spray provided the final step to the volumizing equation, adding additional body and staying power that made the look last all day. An added boon: Both products contain UV filters, so they not only pump up strands but also protect them. --Jamie Stone
