Don't say we didn't warn you. The cold can be brutal about drying your hair out — especially if you have long locks, because it's harder for natural oils to reach your ends. Dove Pure Care Dry Oil ($11) is a drugstore gem that's packed with African Macadamia Oil to add shine. Try it on wet strands before you blow-dry, or run a bit through freshly styled hair for added polish.
