We'll be honest. The very idea of "dry shampoo" sounds a little icky the first go 'round. Adding more gunk to already unwashed hair doesn't quite seem to add up. But we were oh so very wrong. Dry shampoo is not only "not icky" but it could be a lifesaver for the beauty maven on the go. Traveling all day can leave your hair feeling greasy and stringy. Try a dry shampoo like Refresh Volumizing Dry Shampoo ($25).

What it does:
This waterless spray cleans hair without water—absorbing oil and eliminating odor while adding instant lift and volume. Available in three color tones: blonde, brunette, and auburn, Refresh blends in seamlessly with natural hair color without the powdery residue and is totally healthy for hair with its Vitamin B6 formulation. The perfected aerosol design allows a precise and even application without the mess.
