The Alterna Haircare Caviar Anti-Ageing Sheer Dry Shampoo Powder Spray ($25) is a lightweight mist that can refresh styles between washes as sheer, talc-free powder absorbs unwanted oil, moisture, and other impurities, and leaves hair looking and feeling fresh. It's well-regarded by other Sephora shoppers and several note that there's also no white cast on brown hair with this product either.
