When you've skipped a shampoo (or two), these fine powders refresh your style in seconds; use them on clean, dry hair, when you just want extra volume. We recommend spray versions (like Klorane's ECO-friendly Gentle Dry Shampoo, $18; Sephora.com
): Hold the can six inches above your head and direct it along your part, section by section. When you're done, shake hair gently at the roots with your finger tips, wait several minutes for the powder to absorb excess oil, then brush through.
