Lately, it feels like Oprah Winfrey waved her magic wand and shouted, "You get blond hair, you get blond hair, and you get blond hair!" Several actors, including Michael Seater, Colton Haynes, and Zac Efron have switched to lighter locks (though Haynes is now back to his brunette look).

Seater and Haynes dyed their hair because they felt like it, while Efron did it in preparation for "additional photography" for Baywatch, he told Jimmy Kimmel on Thursday (June 30) while promoting his new film with Adam DeVine, Mike and Dave Need Wedding Dates.

Too bad that photography won't happen "for probably a year," according to Baywatch's producers, who wondered — like the rest of the world — WTF Efron was even doing.
