Bumble and bumble Pret-a-Powder Post Workout Dry Shampoo Mist. A fan (and fitness-enthusiast) favorite for that post-gym, mid-heat-wave, or whenever sweaty hair. This quick-drying, dual-stage liquid mist made to specifically to clean and refresh sweaty strands. Plus, it helps absorb oils and helps to eliminate odor. We love a good multi-tasker. Absorbs oil and cleans hair. Eliminates odor. No white cast or residue.
