Short hair, long hair, or anything in-between, the actress has nailed it, again!
Kaley cut off her long, blonde locks in 2014 and has been nailing her choppy crop/shoulder-length bob ever since.
But it was back to her long locks this week when she took to the salon chair for some sexy new hair extensions.
"It's very important for me to change my look after wrapping each season," Kaley Instagrammed on Wednesday (27 April).
"I love playing Penny, but it's good for me to bring it back to Kaley. Last year I chopped it all off, this year I'm doing the opposite... Stay tuned! (Can't wait to read all the negative comments lol)," she added, alongside a selfie stick snap while having her extensions fitted.
We're not sure what she meant by negative comments, because we trawled through a lot of them on her Instagram feed and found none.
Understandable when we FINALLY saw the results some hours later...
"Epic colour," Kaley posted, along with this profile photo (above) of her finished do, created by top celebrity hairdresser Faye Woods – who's known for her work with all the gang on the CBS hit comedy, The Big Bang Theory.
Epic indeed, we LOVE it.
Even though Kaley's extensions looked super-long while she was having them fitted, she opted for a much more natural final length, working her extensions into gorgeous, sexy waves which hit just below her shoulders.
She also kept her roots dark, working her colour blonder and blonder towards the ends.
Very rock 'n roll. And definitely one to file along with Kaley's other hair hits.
