It's pretty common for the lighter haired to opt for darker, richer tones come winter. Actress Rachel Bilson was after such a look for the Golden Globes, and haircolorist Cassondra Kaeding, Redken brand ambassador, delivered. “Rachel wanted to step away from being an ashy blonde so we created a soft brunette color with some subtle golden highlights and a dimensional, beachy vibe," Kaeding said. "Glossing with Redken Shades EQ Gloss is my favorite way to help my clients achieve their ideal color and give their hair gorgeous shine and luster that’s perfect for the red carpet.”
