It’s down to the top 10 contestants on The Voice, and while Coach Christina Aguilera unfortunately lost one of her team members, Josh Logan, she didn’t miss a beat when it came to her hair and styling choices. "This week it was all about a sleek, clean look," Aguilera's hairstylist David Babaii told InStyle.com of her straightened strands, which were a noted change from the previous week’s curls. "Last week was about show," he continued. "Her hair had a Marilyn Monroe-inspired feel, but this week it was just about keeping it classic." To achieve her simple style, Babaii parted her hair and blew it dry using his T3 blow dryer. He then straightened her locks with a T3 iron. “It didn’t need a lot of product!” Instead, he just used hairspray to tame the flyaways. "Christina likes hairspray, so I sprayed it all over to set the look."
