1. Spritz Nexxus Root Exxtend Volumizing Root Lifter ($12) on damp hair, directing the nozzle toward your roots. 

2. Let your hair air-dry, then smooth it with a flatiron like Paul Mitchell Express Ion Style 1.0 ($225). Start straightening hair about half an inch from the scalp (flattening your roots completely will leave your hair too limp). 

3. To add shine and prevent frizz, rub a pea-size drop of Matrix Sleek.Look Sealing Serum ($15) between your palms, then run hands from midlength to ends.
