The Big Bang Theory star - who plays Penny in the show - was previously rocking a shoulder-length style, but has now decided to lop off her tresses into an even shorter 'do.
Taking to Instagram yesterday (23 April), Kaley posted a mirror selfie of herself sitting in the hairdresser's chair with her hand covering her face.
In her snap, her hairdresser Christine Symonds was prepping her barnet with a comb in the mega-swanky Andy Lecompte Salon in LA.
A little white later, Kaley posted another picture of her cut along with the caption: "We did it @clsymonds ! Now let's get some colour shall we ? @andylecomptesalon"
And in her next photos we finally got a glimpse of her finished look, with a beach blonde hue adorning the lengths and ends of her fresh 'do.
She kept her roots dark to create a subtle dip-dye effect and opted for a sleek and straight blow-dry.
Clearly pretty chuffed with her fab new locks, Kaley wrote: "Thanks to this little gem for giving me this killer haircut !!! @clsymonds"
Looking good, Kaley!
