Hair today, gone tomorrow.
Shawn Mendes said goodbye to his signature wavy locks in favor of a buzzcut, a look that had his fans in, uh, Stitches.

Plus, Bella Hadid entered her Marilyn Monroe era with platinum blonde locks and Kyle Richards lightened things up with fresh highlights.
Finally, Kim Kardashian shocked TikTok when she tested out the latest viral makeup trend after losing a bet to her daughter, North West, and Robert Downey Jr. was unrecognizable on the set of his latest project.
