The Contender: Supercharged Root Booster

Big Sexy Hair Full Bloom 72 HR Thickening & Refreshing Spray, $20; ulta.com

Time Claim: 72 Hours

How It Works: Applied pre-blow-dry, amino acids in the spray penetrate strands and hold moisture, preventing humidity from inflating or deflating hairs once they're dry. Strong-hold polymers help lock in volume.

Our Tests Revealed: Several limp-haired staffers loaded up on the floral-scented mist and reported noticeable lift. "I didn't want to wash my hair after three days," says one. Another reports, "My roots flattened a bit on Day 2, but my hair was much fuller for 72 hours."
