Ali Larter at InStyle Hair Launch Party from stylist Harry Josh!

Celebrities came out last night to celebrate InStyle Hair, a new special issue on sale May 8, at a star-studded event hosted by John Frieda Root Awakening and Marchesa at the Hotel Gansevoort Penthouse.

Harry Josh, John Frieda International Creative Consultant, created a stunning red carpet look for Ali Larter.

Explains Josh: “The look I created for Ali emphasizes how naturally healthy and vibrant her hair is. I started by spritzing hair with Root Awakening Detangling Spray, then blow dried in sections using a natural bristle brush to maintain her hair’s own health and shine. I finished the look with a styling crème to add polish to her naturally sleek, full hair.”

Other celebrities in attendance included Olivia Palermo, Jennifer Esposito, Marchesa designers Georgina Chapman and Keren Craig and Shannen Doherty. With a fabulous view of Manhattan from the Gansevoort Penthouse, guests enjoyed an exclusive showcase of Marchesa gowns complemented by John Frieda hair looks. In addition, partygoers were treated to stylish pampering at John Frieda touchup stations.
