Celebrity hairstylist Patrick Melville (who gave intern Christina a makeover in June)styled Mischa Barton’s hair last night for the “Une Journee A Paris” event hosted by Van Cleef & Arpels.

To get the look, Patrick blow dried Mischa’s hair with a Mason Pearson brush, used a one-inch barrel curling iron throughout to create texture, teased the roots to rough up the look and pinned it into an updo.

For products he used Kerastase volumizer (Spray Volumactive), Peter Hantz styling glaze and L’oreal Elnett hairspray to seal it all in.
