The Best Gym-Bag Beauty Hacks of All Time

The hack: The lightweight, hydrating formula works great to help you detangle hair fast. But you can also use it to give yourself a conditioning treatment while you work out. Your typical hair mask would be too goopy and obvious to leave on your hair while you sweat, but a leave-in spray is invisible and also super hydrating. Plus the heat you generate opens your hair's cuticles so they can absorb the formula better. Afterward: rub shampoo into roots if you need it, then rinse and go. Target.com
