The DryBar Detox Dry Shampoo scored top marks across the board. It was the best at absorbing oil, aptly removed sweat and dirt and had the most pleasing scent, leaving our panelistsâ hair feeling cleaner and smelling better than any other dry shampoo we tried. Lululemonâs No-Show Dry Shampoo is made specifically âfor workout warriors,â and after a month of testing, our editors found it to be the only dry shampoo that, no matter how tough or intense the workout, genuinely absorbed all traces of sweat â though it did leave more traces of oil than DryBar. Dove Beauty Refresh + Careâs lightweight formula and adequate absorption of oil and dirt make it a great pick for those who simply cannot fathom spending a lot of money on a hair product, or for those who might just be looking for a little extra time between washes.
