But Bynes isn't the first one to shave half her head. Lately a lot of celebrities have been trying out the look, including Avril Lavigne and Rihanna.
Still, a handful of other female stars have taken their hairstyles a step further, shaving their heads completely. Take Jessie J, for instance: She buzzed off all her hair for charity in March, honoring the U.K.'s "Red Nose Day."
Charlize Theron also got rid of her long blond locks, razoring them off for her role in "Mad Max: Fury Road."
