For last night's New York City premiere of Arthur, actress Greta Gerwig shined in an elegant, draped Narciso Rodriguez gown, and her bold orange lip color — Nars Heat Wave lipstick ($24) — along with her loose, wavy "undo" provided the perfect complements. The man behind the undo, Seiji for Sebastian Professional, crafted the look to work for the red carpet, as well as the afterparty. Find out how to copy Greta's casually glamorous hairstyle (using products from the Sebastian brand) when you keep reading.
- First, Seiji washed Greta's hair with Color Ignite Shampoo and Color Ignite Conditioner. Then, to add volume, he applied Mousse Forte to the roots of her damp hair. (Find a list of salons that carry Sebastian products here.)
- Next, he flipped the hair upside down and blew it about 90 percent dry. He flipped Greta's hair back to finish, making sure to dry in the reverse direction. Then, he set the top section of hair with mesh rollers.
- Seiji sprayed Shaper Zero Gravity directly onto the rollers and, once dry, removed them and brushed through Greta's hair. Then, he used a medium-sized curling iron to add some soft waves. He added texture to the look by finishing up with Volupt Spray.
