Whenever we spot Olivia Palermo — whether it's front row at a fashion show or strutting the streets of NYC — we always get a major case of hair envy. Not only does Olivia have some seriously shiny strands going on, but she also manages to have a healthy dose of movement and body running throughout her style, ensuring that her hair always looks healthy and lustrous. We know that she keeps her style in place with cult classic L'Oreal Paris Elnett Hairspray but the secret to her bounce is prep work. Use a volumising root lift spray or mousse, massaging that into hair before flipping your hair upside down and blast drying the roots. Then blow-dry the rest of your hair with a round barrel brush. Next, swish and sure off the full-bodied style.
