If you've ever spent, like, an hour (OK, two) erecting your coif, only to have the stunning effect wiped out by a rogue rain shower, don't leave your pad without a pack of these (tragically limited-edition) do savers stashed in your back pocket. Made from organic flaxseed and plant-derived starches, the smell rocks, as does the rock-hard styling power. Just wet your hair and hands, put tape strategically in place or dissolve the strip into a gel. Bonus: no bag-wrecking product spillage.
