McDreamy is a blonde: Patrick Dempsey debuts shocking platinum hair

Until the actor (and his coif) left the show in 2015, Patrick Dempsey's hair could have been considered a supporting character on Grey's Anatomy. His thick waves were a big part of what made Derek Shepherd, a.k.a. McDreamy, so, well… dreamy. His iconic dark locks, turned peppered silver with age, have now been traded in for a shocking bleached platinum look.

Fans, at the D23 Expo on Sept. 9, were left shocked when the actor turned up at the D23 Expo on Sept. 9 rocking a platinum dye job.

Speaking to Variety about his new look, the actor revealed, ""I love it, it's great. It's fun to do something different, and unfortunately or fortunately, I'm known for my hair. So this has jacked up a lot of people, they don't really know how to embrace it. Either they love it or they hate it."
