Crystal Harris went from blonde, to brunette, to somewhere in the middle. The wife of Playboy mogul Hugh Hefner posted an Instagram pic of her new 'do, writing: "Added highlights to my new ombre hair. Also put in some fun clip-in extensions courtesy of @bellamihair. I've never had hair extensions that have felt this natural before, Love them. Thank you @bellamihair and thank you to my very talented friend @guy_tang for my hair transformation!"
