To get maximum shine, wash and condition your hair, then blast it with a cold-water rinse for about three seconds. "This helps seal in conditioner, making hair easier to style and adds a ton of shine," says Labrecque.
Blow-dry while brushing with a natural boar-bristle paddle brush. Apply a bit of light finishing serum to frizzy areas (like ends). Finish with shine-enhancing hairspray.
