While Angelina Jolie isn’t known for constantly changing her appearance on the big screen, she has undergone several notable transformations throughout her career. In “Lara Croft: Tomb Raider,” she bulked up with massive muscles, and in “Gone in 60 Seconds,” she dyed her locks blonde for the role. 
However, early in her career, she took her commitment to authenticity even further by sacrificing her crown of hair.
In 1998, Jolie took on the role of the troubled model Gia Carangi in the biographical drama “Gia.” Portraying a character grappling with various challenges, including drug addiction and a tumultuous personal life, Jolie made the daring decision to shave her head for the role. 
This bold move not only showcased her dedication to her craft but also added a layer of authenticity to her portrayal of the iconic figure. Jolie’s willingness to undergo such a drastic physical transformation further solidified her reputation as a committed and versatile actress willing to push boundaries in pursuit of her art.
