The actress appears to have undergone another hair transformation after unveiling blonder locks on Instagram.
Posting a selfie, the Mad Men star looked sensational with her sweeping fringe and hair curled, sporting much lighter locks than her usual red hue.

Christina's porcelain skin looked flawless against a subtle smokey eye and she rocked a plunging black dress and a cute, pink bow in her hair.
The actress's new look could just be for Good Girls though, as Christina appeared to be in character as Beth Boland, captioning the shot: "Beth’s feeling herself. #goodgirls @nbcgoodgirls."
Regardless, her fans went wild for the photo, with one commenting: "I love this look on you!" A second wrote: "This is gonna take me 3-5 business days to recover YOU DON’T UNDERSTAND."

A third added: "OMG I’m deceased. This picture just took me out." And a fourth said: "I don't even know what to say, my pressure has dropped."
Back in January, Christina showed off a super-chic new hairdo having chopped several inches off her gorgeous red hair.
Revealing her new look on Instagram, Christina's mane sat a few inches above her shoulders, but still framed her face beautifully.

Her followers were again quick to compliment the actress, with one commenting: "Your hair is stunning. I love it!" - to which Christina replied: "I was thinking the same!" Another wrote: "Love your hair!"
One fan even compared Christina to The Queen's Gambit star Anya Taylor-Joy. "Your hair and look is giving me The Queen’s Gambit vibes and you’re totally rocking it!!"
