Kaley Cuoco Attempts To Go Full Method With 'Big Bang Theory' Haircut

For some actors, the only way to own a role is to undergo a total physical, mental and emotional transformation. Leonardo DiCaprio ate raw liver and slept in animal carcasses for “The Revenant.” Jared Leto watched hours of violent crime footage and sent his co-stars grotesque gifts to channel The Joker in “Suicide Squad.”

For Kaley Cuoco, chopping off a few inches of her hair and dying it a slightly darker shade of blond is enough to become her “Big Bang Theory” character, Penny. The actress, who recently began filming Season 10 with the rest of the cast, posted a photo of her “transformation” on Instagram.

“Sending mad 💗 and props to @faye.woods for bringing my cut and colour back to its ‘Penny’ roots,” Cuoco said.

See if you notice any differences between her “new look” and the look she was sporting three days prior:

Are we supposed to spot something? Because we’re stuck.

Though a few inches might not seem like that big of a difference to us ― for Cuoco, the tiny, tiny change is just enough to help her figure out if she’s Penny or Kaley.

“It’s very important for me to change my look after wrapping each season :),” Cuoco said in an Instagram post in April. “I love playing Penny, but it’s good for me to bring it back to Kaley. 🙋🏼”
