Kaley Cuoco is rocking the bob no more.

"The Big Bang Theory" star took to Instagram on Wednesday to unveil her new longer locks, courtesy of some pretty impressively applied extensions, writing, "It's very important for me to change my look after wrapping each season."

"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," the 30-year-old actress added. With the extension master @faye.woods .... Stay tuned! (Can't wait to read all the negative comments lol)."

But the haters might be hard to find, judging by her gorgeous "end result." "Baby's got her hair back,” the actress wrote.
